The document summarizes a study on replicating cupules found at the Daraki-Chattan cave site in India to understand how they were created. Over 500 cupules of varying shapes and sizes were discovered on the cave's hard quartzite walls. Through excavations led by the Early Indian Petroglyphs project, exfoliated cupules and hammerstones used to make the cupules were found stratified in the cave's sediments, demonstrating the cupules were Lower Paleolithic in age. The authors classified the cupule shapes and initiated a replication project using an experimental rock panel, continuing from 2002-2012. Their goal was to understand how the cupules were made and what technology was used given the hardness of
The prospecting and mining of base metal in India
dates back to 3000 B.C. All the base metal deposit of India has
surface manifestations in various forms. From 19th century to the
middle of the present century, certain European companies
started a modern phase of base metal exploration and
development. Earlier, the search for base metal was confined to
the close study of surface features. In 1940 ground geophysical
survey work has been introduced in order to search the mineral
deposits. The total world production of lead and zinc metals are
about 3.9 and 11.4 million tonnes respectively in 2009. The
leading producing countries for lead is China (41% of world
production), followed by Australia (15%), USA (10%), Peru (8%)
and Mexico (4%). The Indian production of lead and zinc ore is
7.10 million tonnes in the year 2009-10, it includes 136095 tonnes
of lead concentrate and 1224077 tonnes zinc concentrate. In
India, the Western Indian Craton (Rajasthan) is the main
provider of base metal to the country. It contributes nearly 85%
of the estimated lead and zinc. In Western India Craton, the main
metallotect of lead and zinc from an elongated NE – SW trending
polygon, this covers an area of about 20000 sq. km. It comprises
three metalliferous belts mainly, the Pur-Banera belt, the
Rajpura-Dariba- Bethumni belt, and the Sawar belt and two
metalliferous enclaves namely; the Agucha and the Kayar
enclave.

This document discusses National Publishing Company's fortnightly children's magazine called Titli. It has short stories, cartoons, puzzles and more, targeting children ages 5-14. Customers are segmented by age into active promotion (ages 3-5), passive approval (6-8), and active control (9-10). While Titli has a 47% market share, the magazine market is declining. Threats include substitution from TV, English magazines, and science journals. Suggestions include better positioning through content changes for the largest group, releasing an English version, and school outreach shows. Market penetration could increase through informative content and institutional sales through schools. Anticipating trends, diversification into cart

The Middle Stone Age was a period of human development in Africa between 280,000-50,000 years ago where particular stone tools originated. It was once thought to be equivalent to Europe's Middle Paleolithic but evidence of art and symbols in the MSA has challenged this view. The Neolithic period began around 10,200 BC in the Middle East and later elsewhere, ending between 4,500-2,000 BC. It followed the Epipaleolithic and saw the beginning of farming in the Neolithic Revolution. During this time, wild crops and domesticated animals came into use.
Drawing from findings of a survey conducted by Dr. Leanna Wolfe and funded by Avid Media, the owner of the Ashley Madison website, recent trends towards increased openness about anal sex are dissected. Ultimately an interest in anal play among married heterosexuals is not a significant motivator towards cheating. Non-kink identified respondents engaged in anal pleasuring on average a couple of times a year.
The document summarizes and discusses the two main theories for the origin of Homo sapiens: Out of Africa and multiregional. The Out of Africa theory proposes that Homo erectus migrated from Africa and evolved separately in different regions, with Homo sapiens emerging only in Africa and later migrating to replace other populations. The multiregional theory suggests that Homo erectus populations evolved into Homo sapiens across different regions simultaneously through interbreeding. While both theories are discussed, the document expresses a personal support for the Out of Africa theory based on perceived stronger evidence.
Cultural Transmission from an Archaeological PerspectiveFSCONS
Human beings have been copying and reusing culture and technology for approximately 2.6 million years. Access to new cultural advancements have been crucial for all human societies during all of prehistory.
With this presentation I want to give an archaeological perspective on today's issues of free software, free culture, patents and copyright. I am going to give examples on how humans have copied and reused culture and technology through out all of prehistory with concrete archaeological examples, mainly from the stone age. I am also going to show examples of how people have been trying to limit access to ideas and technology for others.
The presentation will focus on these questions:
What does the possibility to copy culture and technology mean for human societies and how does people profit from limiting the access to these cultural traits and technologies for others?
Does culture have an intrinsic wish to be copied? Does culture in fact want to be free?
Keywords: Stone Age, Memes, Cultural transmission.
The document discusses the Precambrian-Cambrian boundary, which saw major biotic changes like the emergence and extinction of soft-bodied Ediacaran fauna and the emergence of organisms with hard parts. Trace fossils from this period provide important stratigraphic information. In India, sections in Kashmir and Spiti Valley contain microbiota and trace fossils that help delineate the boundary. The Precambrian-Cambrian transition witnessed an evolutionary explosion of life and the emergence of many new animal phyla. Detailed study of sections in the Himalayas continues to provide insights into this important period in Earth's history.

The document discusses the K-T boundary problem, which marks the end of the Cretaceous period and the mass extinction event that wiped out the non-avian dinosaurs. The boundary is associated with the Chicxulub impact crater formed by an asteroid strike around 66 million years ago. Evidence suggests this impact triggered widespread environmental changes through effects like sulfur aerosols that blocked sunlight, causing a global climate shift and 75% of species to go extinct. Debate continues around other potential contributing factors like the Deccan Traps volcanic eruptions. The document provides details on the lithology, fossils, and occurrences of the K-T boundary in different regions including India.
Development of copper technology in ancient indiaPrachya Adhyayan
1) Copper was widely used in ancient India from as early as the 5th millennium BC based on evidence from sites like Mehrgarh and Nal.
2) During the Indus civilization between 2600-1900 BC, copper, bronze, and other metals like lead, silver, and gold were commonly used to make vessels, tools, weapons, and ornaments as seen at major sites.
3) After the Indus civilization, copper use continued and spread to other parts of India as seen in artifacts from late Harappan sites as well as Neolithic and Chalcolithic sites across the subcontinent.
This document summarizes research on the lack of chert artifacts found at archaeological sites in the northern Maya lowlands region, known as the "Chert-Free Zone". Excavations in the Yalahau region of Quintana Roo yielded extremely small amounts of chert tools and debris compared to ceramic sherds. The document hypothesizes that a Chert-Free Zone can be defined based on the local geology, which lacks chert inclusions in the surface limestone deposits. Three hypotheses are presented to explain how the ancient Maya may have coped without access to local chert for tool-making.

This document provides a review and geological classification of ruby deposits. It discusses how rubies form in various geological environments, including metamorphic belts and alkaline basaltic volcanism. Ruby deposits are classified as either primary, containing rubies in the rocks where they crystallized, or secondary, containing rubies eroded from primary deposits. Primary deposits are further divided into two types - magmatic-related deposits containing ruby xenocrysts in igneous rocks, and metamorphic-related deposits formed in metamorphic environments. Secondary ruby deposits are sedimentary placers formed by erosion of primary deposits. The value of rubies depends on factors like origin, treatments, and size rather than just weight.

1. Archaeologists have discovered a complex of megalithic structures and stone circles dating to around 6,000-7,000 years ago at Nabta Playa in southern Egypt.
2. The structures include five alignments of standing stones that radiate outward from a central megalithic structure, as well as a small stone circle that may have been used to track the summer solstice.
3. Radiocarbon dating indicates the ceremonial complex was built during a period of increased rainfall and lake formation in the region between around 7,000-6,700 years ago, before the area again became too dry to support human habitation around 4,800 years ago.

Ancient Dwarka Study based on recent underwater archaeological investigation...Karen Benoit
The document summarizes the findings of recent underwater archaeological investigations off the coast of Dwarka, India. Semicircular, rectangular, and square stone structures were discovered in water depths from the intertidal zone to 6 meters. A large number and variety of stone anchors were also found among and beyond the structures. The discoveries suggest Dwarka was an important port center in the past on India's west coast. Comparative studies of surrounding sites indicate the structures date between the historical period and late medieval period. The paper reviews earlier hypotheses about the identification and dating of the structures in light of the new evidence from the recent underwater explorations.
Karai badland topography and Geo-Heritage site, Take A Geotourism around Grav...sutikshandwivedi
The Karai Badlands national geological monument is located in the Karai area along the Karai-Kulakkalnattam road of Perambalur District, Tamil Nadu. A four km. the stretch of badlands with natural conical mounds and typical fossils of the Cretaceous age is exposed as badlands with a series of conical mounds separated by gulleys.
Badland topography, on either side of Alattur-Ariyalur road, spread within 40-70 km. radius marks the lower part of marine Cretaceous rocks that mainly consists of clay & sandstone of the Karai Formation. Like the Grand Canyon in Colorado, US, Ariyalur is considered a Cretaceous Park of South India by Geo-scientist.
The Geological Survey of India (GSI), has declared Karai Badland as a National Geological monument for its maintenance, protection, promotion, and enhancement of geo-tourism.
Stratigraphy
The Rock formation is here exposed to the Cretaceous of Trichinopoly, Which dates back to the Late Cretaceous. The Succession in the area is broadly divided into 4 Groups -Uttathur, Trichinopoly, Ariyalur, and Ninniyur, Where Uttathur is the oldest. After comparing the age and color of the rock formations here with those of the Himalayas, we have found that they are of the same age. The Karai Formation of Uttatur Group at the Karai-Kulakkalnattam section in the Perambalur district forms the lower part of the Cretaceous sedimentary succession of the Cauvery Basin.
The Karai Badlands area is the type area for Karai Formation. The Karai Formation is exposed as badlands with a series of conical mounds separated by gulleys. It is a wasteland with scanty vegetation and without any topsoil on either side of Karai-Kulakkalnattam road.
The Karai Badlands Formation consists of grey-brown, gypsiferous, glauconitic mudstone, and marl with sporadic thin interbeds of siltstone and calcareous sandstone, particularly in its upper part- sporadic calcareous, siderites and phosphatic concretions/nodules and concretionary horizons occur in some intervals. A variety of marine fossils like ammonites, nautiloids, belemnites, worm tubes, pelecypods, gastropods, and oysters occur in abundance.
The importance of this “Geoheritage Site” lies in the fact that it provides one of the best-exposed sections of Cretaceous rocks with its unique lithology and diversity of extinct marine life. The region is a magnet for cement companies because of the purity of Ariyalur’s limestone. The factories burn a mixture of powdered limestone, gypsum, coal, and other chemicals to produce cement and clinker. But unchecked mining has led to air pollution and large quantities of overburdened soil being heaped up randomly.
How Badland is a form
The Cretaceous Period (135- 65 Million Years) witnessed a series of major geological events in the history of the Earth. Of these, the most significant is the worldwide marine transgression, which has left its mark in many parts of the world including South India.

A representation of an anoa — a type of dwarf buffalo — and human hand stencils from a cave in Sulawesi, Indonesia. New dating results challenge the traditional view that western Europe was the centre of a crucial stage in the evolution of modern human intelligence and culture — based largely on the emergence of figurative or representational art in cave paintings and sculptures around 40,000 years ago. New dating data on a series of hand stencils and paintings of wild animals from caves in the Maros karst in Sulawesi, Indonesia, suggest that figurative art appeared at more or less the same time at opposite ends of the Late Pleistocene world. Or was cave painting practised by the first Homo sapiens to leave Africa tens of thousands of years earlier? Cover: Maxime Aubert.
Tell El-Hibeh Limestone: Ancient and Modern Egyptian Quarrying Technology wit...CrimsonPublishersAAOA
Limestone and its interbedded marl deposits form an economic resource that was utilized at El-Hibeh, ancient Teudjoi/Ankyrononpolis, a tell mound in middle Egypt. The archaeological site contains the small Amun temple, at least two limestone (packstone) quarries, statues, sarcophagus lids and bases, limestone (packstone) construction blocks with and without relief, and major mudbrick structures. The temple blocks are made from a local packstone-limestone that has been saturated by Nile River water and is deteriorating at a rapid pace. The limestone at El-Hibeh is a packstone. Several packstone quarries occur in the archaeological site. One appears to be of recent vintage and was mined using modern drilling and blasting techniques. Another is an ancient quarry that utilized natural sedimentary and structural features of the packstone-marl deposits to manufacture blocks for various utilitarian purposes.

Seismic Reflection Surveys in Search for Iron Oxide Copper-Gold (IOCG) Depositsiosrjce
Seismic reflection method can delineate very complex geological structures hence it might be very
effective for detecting the presence of Iron Oxide Copper-Gold (IOCG) deposits. Despite this superior
attributes, there exist a real problem for exploration beyond the immediate vicinity of a known deposit. All
previous studies have focused upon high resolution detection of mineralization and the hosting structures at
mine scale. No argument for “regional” exploration have been proposed probably because a cost benefit
analysis has never be conducted at such scale to proceed with such exploration venture. In this study, we
analyze the feasibility of such regional exploration by modelling a Vulcan IOCGU deposit scenario were a 2D
seismic survey with relatively sparse source-receiver geometry was used to detect the presence of a possible
intrusive package within 2km depth range. The modelling results demonstrates that seismic reflection method
using 10m geophones and 20m shot spacing can be used to image deposit within the depth of 2km. The
presence of reflections was visibly observed especially at the edges of intrusive packages hence it is suggested
that application of seismic reflection methods perhaps will remains the best alternative and most viable method
for exploring deep seated IOCG

UNDERSTANDING THE TECHNOLOGY OF THE
DARAKI-CHATTAN CUPULES:
THE CUPULE REPLICATION PROJECT
Giriraj Kumar and Ram Krishna
Abstract. The Lower Palaeolithic cupules in the small cave of Daraki-Chattan are of different
shapes and sizes. How they were made is the subject of this investigation. The hardness of the
quartzite rock of the cave adds to the complexities in understanding the production process.
The study of the more than 500 cupules on the vertical walls of the cave is a joint venture of
Indian and Australian scientists, the EIP Project. The senior author commenced a program of
replicating the cupules, in an effort to understand the circumstances of their creation, on an
experimental rock panel close to Daraki-Chattan in 2002. The project of replicating different
kinds of cupules encountered in Daraki-Chattan has been continued since then and was joined
by the second author in 2004. This paper presents the gist of the replication project from 2002
to 2012.
Introduction
Daraki-Chattan is a small, narrow and deep cave in
quartzite buttresses of Indragarh Hill near Bhanpura,
district Mandsaur in Madhya Pradesh, India (Fig. 1). It
was discovered by our friend Ramesh Kumar Pancholi
in 1993 (Pancholi 1994). The cave is slightly more than
4.0 m wide at the dripline, and 1.4 m at its mouth. From
here it continuously narrows down in width, to 34 cm
at a depth of 7.4 m, it then becomes slightly wider, up
to 40 cm, finally closing at the depth of 8.4 m from its
mouth. The cave is maximal 7.4 m in height. It bears
more than five hundred cupules on both of its vertical
walls.A cupule is a petroglyph of hemispherical shape
or its variation, created by percussion technique on a
horizontal, inclined or vertical rock surface.
The cave overlooks the valley of the river Rewa
which opens in front of it into nearly 3-km-wide
agricultural fields. The area was a dense forest with
rich fauna including tigers even just 50 years back, in
the 1960s. The hills and their foothills on both sides
of the river were also a rich source of quartzite for
manufacturing of stone artefacts by hominins in the
Lower Palaeolithic, as indicated by extensive surface
occurrences of artefact scatters as well as in stratified
exposures. We discovered early Acheulian factory
sites with finished artefacts, big flakes and cores from
nearby, especially from the foothill on the opposite hill
on the right bank of the river and on the Chanchalamata
HillnearDaraki-Chattan.WealsodiscoveredAcheulian
artefacts on the plateau of Indragarh Hill above the
cave, as well as artefacts representing the transitional
phase from Lower to Middle Palaeolithic industries
from inside the cave. No other artefacts of later cultural

phases were found in Daraki-Chattan in 1994–95,
hence one of us postulated that the cupules inside the
cave may belong to the Acheulian or the following
transitional phase (Kumar 1995, 1996).
Most of the first half portion of the southern wall is
devoid of cupules on its surface (Fig. 2). It must have
beenexfoliatedandfallenbelowandbecomestratified.
This meant that the sloping sediments in front of the
cave should contain pieces of cupule-bearing slabs
and also some of the hammerstones used for their
production. Both were indeed amply found during
excavations (Kumar et al. 2005; Bednarik et al. 2005).
The EIP Project
In order to study the early cupules in India and es-
tablishingtheirantiquitytheEIPProjectwasestablished
during the Third AURA Congress at Alice Springs in
2000. Its name is an acronym of Early Indian Petroglyphs:
Scientific Investigation and Dating by International
Commission.ItisajointventurebyIndianandAustralian
scientists conducted in collaboration of RASI and
AURA under the aegis of IFRAO, with Giriraj Kumar
and Robert G. Bednarik as its Indian and Australian
directors. It has been supported and supervised by the
Archaeological Survey of India. Support was also given
by the Indian Council of Historical Research and the
Australia-India Council, Canberra.
Under the EIP Project excavations were carried out
at Daraki-Chattan for five seasons from 2002 to 2006,
under the supervision of the first author (Kumar et al.
2005; Kumar 2006), and 325-cm-thick sediments were
excavated. The preliminary results of the EIP Project
have been published in India, Australia and other
countries from time to time (Kumar et al. 2002, 2005,
2012; Kumar 2008, 2010a, 2010b, 2010c; Bednarik et al.
2005; Bednarik 2009a, 2012; Bednarik and Kumar 2012;
Krishna and Kumar 2012a, 2012b, 2012c). However,
a summary of the excavations is provided
here to define the typological-cultural deve-
lopment of lithics and correlation of the ex-
foliated cupules and hammerstones found
in different layers with them.
Summary of the excavations
The Lower Palaeolithic stone tool se-
quence in the Daraki-Chattan sediments
commences from the uppermost levels of the
floor deposit, which comprises only a very
thin layer of more recent strata. In places
an industry intermediate to Middle and
Lower Palaeolithic (MP and LP) typology
was visible at the surface before excavation
commenced. These intermediate tool types
are underlain by a substantial deposit de-
fined as Acheulian, but poor in typical
handaxes and cleavers. Six vague and fairly
arbitrary layers were distinguished in the
sediment, becoming progressively more
reddish in layer 5 (Bednarik et al. 2005: Fig.
26). The lowest sediment deposit is characterised
by its red colour, the upper part of which contains
severely weathered Mode 1 cobble tools as well as
hammerstones of the type used to produce the cupules
(Figs 3–5, 8a).
Arbitrary sediment layers 3 and 4 contain LP flake
artefacts,some made fromriver cobbles, but most made
of the local purplish quartzite. A few artefacts consist
of deeply patinated cherts. Layer 5 contains still much
the same industry, but increasing iron content has
effected a more reddish colour. Both stone tools and
clasts show increasing effects of weathering and iron
induration with greater depth, which on large clasts
may take the form of thick mineral crusts of primarily
ferromanganese composition.
The basal sediment layer features only very wea-
thered stone tools and clasts. Tool types from the lower
sedimentsinclude cobble tools, discoids, core choppers,
flake scrapers and polyhedrons similar to the so-called
Durkadian (for references for the following summary
see Bednarik 2009b; Bednarik and Kumar 2012). A
few specimens resemble what have been called core-
scrapers at Mahadeo-Piparia, another central Indian
site, whose repertoire has been called the Mahadevian.
These characteristic pieces are large blocks with a
zigzagging edge produced by chunky flakes having
been removed alternatively from each side.
Although LP and MP stone-tool traditions are
widespread in India, represented in massive quantities
and typologically accounted for, their absolute
chronology has remained largely unresolved so far.
This is due both to a paucity of excavated sites (most
known sites are surface scatters) and a pronounced
lack of well-dated sites. The cobble or chopping tools
preceding the bifaces of the Indian Acheulian have
attracted comparatively little attention.
While the Lower Acheulian remains largely un-

dated, preliminary indications suggest a late
Middle Pleistocene antiquity for the Final
Acheulian. Thorium-uranium dates from
three calcareous conglomerates containing
Acheulian artefacts (Nevasa, Yedurwadi,
Bori) suggest ages in the order of 200 ka. The
most recent date for an Indian Acheulian
deposit is currently the uranium-series
result of about 150 ka from a conglomerate
travertine at Kaldevanahalli. There remains
wide disagreement about the antiquity of the
Early Acheulian and the Mode 1 industries.
Some favour a date of 1.4 million years (Ma)
from Kukdi valley for the earliest phase of
the Acheulian; others reject it. The earliest
phase of human presence in India, of Mode
1 assemblages, remains largely undated, but
at Pabbi Hills, dates ranging from 2.2 to 1.2
Mahavebeenacquiredbypalaeomagnetism.
The few flaked quartzite cobbles from Riwat
(Pakistan) appear to be in the order of 2.5
Ma old, rather than 1.9 Ma as previously
proposed. The claims from Labli Uttarani,
ranging from 1.6 to 2.8 Ma, are viewed
sceptically. However, the earliest data from
China imply an occupation by hominins
prior to 2 Ma, which presumes human
presence in India by that time. Reliably
identified Mode 1 industries have been
excavated from secure stratigraphies in very
few cases, and they were found below Mode
2 (Acheulian) strata at the two early cupule
sites, Auditorium Cave at Bhimbetka and
Daraki-Chattan. These quartzite tools are
partially decomposed at both sites and they
were found in both cases below pisoliths and
heavy ferromanganese mineral accretions
indicating a significant climatic incursion.
Details of the typological context of the
excavated tools from Daraki-Chattan have
been published by Bednarik and Kumar
(2012: 154–55, in CD pp. 895–906).
The excavations at Daraki-Chattan have
established that the cave was a Lower Pa-
laeolithic occupation site (Figs 3 and 4).
During the excavations exfoliated cupules
and hammerstones used for the creation of
cupules (Fig. 5) were obtained from arbitrary
layer 3 down to arbitrary layer 4, 5 and from
the interface of 6/5 (Bednarik et al. 2005: Fig.
26). It means the cupules on the excavated
slabs must have been much older than their
stratigraphical antiquity, and this applies
also to the cupules on the cave walls. Thus,
the EIP Project has confirmed the evidence of
Lower Palaeolithic cupules for the first time
in the world.
It also established that with more than
five hundred cupules on both vertical walls,

Daraki-Chattan is the richest known early Palaeolithic
cupulesiteintheworld(Fig.2)(Kumar1995,1996,2006;
Kumar et al. 2005; Bednarik et al. 2005).
Inadditiontohousingsomeoftheoldestknownrock
art, Daraki-Chattan is also an important Palaeolithicsite
because it is one of the very few Indian locations where
Mode 1 (pre-Acheulian) occupation evidence has been
excavated in a stratified context. Overlain by a typical
Acheulian with handaxes, this deposit has yielded very
simple,Oldowan-likestoneartefactsmademostlyofthe
local quartzite. This very early cupule site is therefore
of particular importance to exploring the LP industries
of southern Asia (Bednarik and Kumar 2012: 154–155,
in CD pp. 895–906).
Questions raised by Daraki-Chattan
The high concentration of cupules in a small cave
such as Daraki-Chattan requires an explanation. The
hardness of the quartzite rock of the cave adds more
complexities to its understanding. Common questions
being raised in reference to this site are:
1. How were these cupules made on such a hard
quartzite rock?
2. Were these cupules the creation of a single period
or were they made in different periods, and when
were they made?
3. DothecupulesinDaraki-Chattanshowadiachronic
development?
4. What was the purpose of creating such a large
number of cupules on such a small and narrow
cave?
5. What is the significance of the study of these
cupules?
Until c. 2001 it was impossible to answer such
questions scientifically. The study of the early pet-
roglyphs through the EIP Project has focused on being
able to answer some of these questions.
Study of the cupules
We made a preliminary study of the cupules in
Daraki-Chattan Cave while documenting them in
1994–95 (see Kumar 1996: Figs 5, 6). However, for
understandingthecreationofcupulesinDaraki-Chattan
through replication it was necessary to understand the
cupule forms more closely.
Categories of cupule forms in Daraki-Chattan
We studied and documented 496 cupules on both
walls of Daraki-Chattan Cave in 1995. Out of these,
402 cupules are circular or almost circular, 85 are
elongated (oval) and 9 are more angular in shape. Of
the circular cupules we distinguished two categories
in 1995: (1) saucer-shaped big circular cupules, and
(2) bowl-shaped big circular cupules (Kumar 1995).
However, later on we observed that circular cupules
have one more category: circular cupules with conical
section (Kumar and Prajapati 2010; Krishna and Kumar
2012a).
Almost all the cupules and the bedrock around
them bear light-brown patina. Most of them also bear
mineral encrustation and also show different stages of
weathering. Later on a few more cupules have been
observed near the roof of the cave on the southern wall,
and two on the bedrock of the cave floor. Besides, slabs
bearing 28 cupules were excavated during 2002–2006,
out of which two cupules were in situ (Kumar et al.
2012).
The archaic cupules in Daraki-Chattan Cave have
now been classified broadly into four categories with
their sub-categories as follows (Kumar and Prajapati
2010; Krishna and Kumar 2012a):
1. Big circular cupules with saucer-shaped floor or
deeply rounded floor (Fig. 6):
1a. Big circular cupules of more than 50 mm dia-
meterandsmoothsaucer-shapedfloor,ofmorethan
5 mm depth.
1b. Big and deep cupules of about 30 to 50 mm dia-
meter and 7 to 12 mm depth, smooth and rounded
floor; sometimes the depth is more than 12 mm.
2. Cupules with conical section:
2a. Circular cupules of about 30 to 40 mm diameter
and conical section of more than 5 mm depth (Fig.
7).
2b. Oval or elongate cupules with oblique and
conical section, deepest point is always below the
cupule’s centre (Fig. 8).
3. Small cupules:
3a. Small circular and shallow cupules which
appear to be unfinished.
3b. Small circular cupules with deep smooth
floor.

4. Small cupules with angular periphery and deep
angular section. They are rare:
(1) Northern wall, on the lower side before Group
1a: 18.3 × 17.6 × 5.7 mm, with roughly triangular
periphery and angular section (it is a new cupule
observed on northern wall of the cave on 27
December 2008, hence has no number).
(2) SR 23 (Fig. 9); 27.3 ×24.6 × 8.4 mm, with roughly
triangular periphery androughly triangular section.
It is the only case of its kind and is exceptionally
difficult to produce.
(3) However, in the study of the cupules in DC in
January 2012 we observed a few more specimens
with angular periphery. Near the distal end of
the southern wall, cupule SR 174 is deep and with
roughly square periphery (Fig. 10). It could be
identified on close observation. Close to and slightly
belowit,cupuleSR200isroughlytriangularinshape

in Daraki-Chattan Cave. Category 3 forms only a small
part, while cupules of category 4 are rare. Cupules of
category 2 have been found from the excavations at
Daraki-Chattan.
Replication of cupules
In the global literature (Bednarik 1998: 23–35) on
rock art we do not have any reference for replication
work that could have helped us in understanding
the techniques used, cognition and skill required and
complexities involved in producing the cupules on
hard quartzite rock. Hence, in order to understand
the creation of cupules and their significance in
Daraki-Chattan we have been experimenting with the
replication of cupules on a selected vertical wall in a
rockshelter closely associated with and located by the
right side (south) of Daraki-Chattan (Fig. 11). It is a
continuation of the same quartzite bedrock forming
Daraki-Chattan. The rockshelter, 660 cm in breadth

at the dripline, 175 cm deep and
275 cm in height at present, faces
west. The vertical wall of the
shelter runs 210 cm from north
to south, than turns to southeast
for an additional distance of 140
cm. It is 200 cm in height from the
present floor surface.
We really need to show how
hard it is to make the described
different types of cupules and
how much deliberate effort is
required in their production. Secondly, we also need to understand and
justify the nature and types of hammerstones discovered in the excavations
at Daraki-Chattan and correlate them with the cupules in the cave (Fig. 12).
Experiment with replication of cupules was commenced by GK in 2002,
the year of beginning the excavation at Daraki-Chattan. Ram Krishna
(Prajapati) joined the replication project in 2004. It is still continuing (Kumar
and Prajapati 2010; Krishna and Kumar 2012a, 2012b, 2012c). So far we have
replicated ten cupules.
Hammerstones used for practical work
Pebbles and cobbles from a nearby site, Patasighati, with purple-red
coloured core, are very hard and are most suitable for use as hammerstones
for cupule production and also to make artefacts from. They are of greater
density than the bedrock of Daraki-Chattan. They were similarly used at
this place by hominins in the Lower Palaeolithic. We also experimented with
hammerstones on chert, chalcedony, and basalt and other igneous rocks, but
they were not found suitable because of their fragile nature.
Patasighati is located in between Indragarh Hill and Chanchalamata Hill.
It contains highly cemented thick boulder conglomerate of river deposit in a
palaeochannel. So far we could not find any stone artefact or fossil remains
fromthispalaeochanneldeposit.Itmusthavebeenformedbyaverypowerful
stream of very high kinetic intensity, as the boulders up to 50 cm diameter
have become almost round, some are flat and round, hence the local name
Patasighati (valley of boulders, cobbles and pebbles like sugar cakes).
Technique used
From the study and observation of the hardness of the bedrock and
smoothness of the archaic cupules in Daraki-Chattan, GK believed
intuitively from the very beginning that these could have been produced by
direct percussion technique; hence he used the same technique for cupule
replication unless mentioned otherwise.
Summary of the replication project,
study and observations to date
The details of our replication project on different shapes and size of
cupules (Figs 13–17) and the shape of different hammerstones after their
use (Fig. 18–21) have been reported from time to time (Kumar 2010c;
Kumar and Prajapati 2010; Krishna and Kumar 2012a, 2012b, 2012c). Hence,
instead of giving these details we are presenting here a summary and a
comparative study of the replication process in Table 1. It is followed by
our understanding of the creation of different cupule forms and overall

Comments
Our replication experiments on hard quartzite rock
by the side of DC from 2002 to 2012 have revealed some
facts about the creation of different forms of cupules in
Daraki-Chattan Cave which are as follows:
1. It is incredibly hard to replicate cupules on hard
quartzite rock. Besides, it requires immense skill
and precision.
2. Big circular cupules. In Daraki-Chattan, cupules of
category 1a, i.e. big circular cupules of more than
50 mm diameter, more than 5 mm deep and saucer
shaped, appear to be the work more of strength and
commitment and less of skill. They were produced
by using a very simple technology of direct
percussion. They appear to represent the earliest
stage of cupule production. Our cupule replication
experiment indicates that to produce cupules of
category 1a needs two to six hammerstones on
cobbles to produce such cupules, depending on
the quality of the stone used and the strength of the

A roughly triangular shape of cupules became possible
because of the further experiments in the small circular

direct percussion is a work of high precision and great
patience and commitment. It is the further advanced
stage of cupule creation after the creation of small circular
cupules with conical depth. Its creation requires proper

small circular cupules with conical depth.

A small conical cupule with conical depth produced by
direct percussion forms the base to produce a triangular
form of cupule. If we shift the centre of the depth, the
cupule form will change to angular form. In the case of RC-
10 it was shifted downwards by 4–5 mm (Fig. 17).
Further, it needs innovative skill and reflects on the
advanced stage of the cognitive development of its author.
Size of an angular cupule is a function of time and also of
finding or making a suitably long and thin hammerstone.

3. Small circular cupules with conical section.
We successfully replicated such cupules
in December 2008 and June 2009. They
appear to be the work of modified
technologyofdirectpercussionwithsmall
hammerstones of specific shape and size.
It requires proper planning, immense skill
and great precision and patience to produce such
cupules. The person at work on cupule production
cannot afford a wrong stroke, even in a thousand, as
it increases the diameter of the cupule. Thus, these
cupules are a work of modified technology and
advancedskillandprecisionandgreatconcentration
and patience. Their creation needs comparatively
light strokes and use of multiple hammerstones. It
also reflects a tradition of long experience.

5. Roughly triangular cupules. A small cupule with
conical section produced by direct percussion forms
the base to produce a roughly triangular form of
cupule. If the centre of the depth is shifted, the
cupule form will change to a roughly triangular
form. It is the main finding of our study of the
cupules in Daraki-Chattan, their close observation
and discussion followed by replication work during
January2012.Further,itneedsindividualinnovation
and reflects on the advanced stage of the cognitive
development of its author. Its production requires
light strokes applied over longer time, compared to
small circular cupules with conical section.
6. Study and understanding of the creation of roughly
angular form of cupules may help to understand the
invention and development of geometrical forms,
especially the triangular and square forms in terms
of antiquity in the Stone Age. It will also help in
understanding the antiquity of the cognitive and
cultural development of their authors.
7. Cupule creation is definitely not a leisure work or
ludic. It is a very tough job and appears to be closely
associated with something special and deeply
significant.
8. Cupule replication is found to be an important
methodforunderstandingtheprocessandtechnique
of cupule creation, in the present case on hard
quartzite rock. It renders hypotheses testable; hence
it is an important scientific exercise.
Conclusions
1. In addition to housing some of the oldest known
rock art in the world, Daraki-Chattan is also an
important Palaeolithic occupation site because it is
one of the very few Indian locations where Mode
1 (pre-Acheulian) occupation evidence has been
excavated in a stratified context. Overlain by a
typical Acheulian with handaxes, this deposit has
yielded very simple, Oldowan-like stone artefacts
made mostly of the local quartzite. This very early
cupule site is therefore of particular importance
to exploring the Lower Palaeolithic industries of
southern Asia (Bednarik and Kumar 2012).
2. It is incredibly hard to replicate cupules on hard
quartzite rock. Besides, it requires immense skill
and precision.
3. Thereplicationofcupuleshelpedusinunderstanding
thattheircreationonhardquartziterockisaverylong,
hard and labour-consuming task, involving literally
tens of thousands of strokes with hammerstones.
The struck rock being very hard, the hammerstone
rebounds with equal force with each stroke, and
gives a powerful jerk in the shoulder of the worker,
especially in case of cupule replication of categories
1a and 2a. Hence, the person working on replication
of cupule creation must have sufficient physical
strength, commitment, stamina and patience.
4. Big circular cupules, small circular cupules with
conical depth and roughly triangular cupules
created by direct percussion method may reflect a
steady advancement in technology, skill, precision,
intelligence and cognitive development in early
human history of the Pleistocene. It appears a
phenomenon more of the social and cultural
environment and also that of opportunities and
encouragementprovidedbythesocialgroupsrather
than evolution of skill in different species of the
Homo. The same is the case even at present when
we observe the development of juveniles in rural
and urban environment in different parts of the
world. We can also recall the Industrial Revolution
and development of bicycles, motor bikes, cars,
aeroplanes etc., from their modest forms in the
beginning to the modern advanced forms of the
present. The underlying nature of the culture of
our ancestors was not significantly different in a
qualitative sense from our own. Of course in the
Stone Age the development was a slow process.
Different technologies, designs, devices and
equipment were developed according to the need
of the time to make the tasks comparatively easy
and life more comfortable. Thus, cupule creation
of different forms by early humans appears to be

the cognitive development in hominins.
