IT DESCRIBES BILINGUALLY MAMMAL ANCESTORS OF MESOZOIC ERA NEAR TRIASSIC JURASSIC JUNCTION FROM PROBAINOGNATHUS TO MORGANUCODON IN SEMI POETIC STYLE .

1. Transitional forms Chapter 2 .2

2. Transitionalforms
Probaingonathus
I am also a small reptile
Which roamed in ‘South America’
During Triassicperiod
And became well known for my jaw
As its joint articulation
Hintedat the directionof the
Mammalian evolution .

4. Transitionalforms
Tritylodon
We were warm blooded!
mammaliamorpha Cynodonts
which laid eggs or delivered
half developed‘babies’
were vegetarians, which lived
in underground burrows
but enjoyed semiaquaticlife.

6. Transitionalforms
Oligokyphus
Lookingmore likea mammal
Than reptile
A small guy with longishbody
and a long tail
Warm blooded, Quiteactive,
vegetarian
Lived mostlyunderground
In burrows .

8. Transitional forms
Diademodon
Quitelarge -
A sixfooter !
looking like
A calf !
Was vegetarian ?
Or omnivorous?
Uncertain
No one sure.

10. Transitionalforms
Adelobasileus
Lookingmore like
A big mouse
With moustaches
And a tail
Therapsidancestor
Of all mammals .
Livingin burrows
Eatinginsects
Roamedjungles in
Triassicperiod.

12. Transitionalforms
Morganucodon
( Morgie)
Lookinglikea shrewor mouse
with longishface, moustaches
Lot of hairsand a long tail
Small,just four incheslong
exhibitingplantigradelocomotion
Livingin jungles or near them
Eating by mammalianteeth-
preferring a dishof beetles
Hiding in burrows during day
Comingout at night for shikar
Laying eggs and raisingyoung
by lactation, likemonotremes
Perhaps the very firstto do so
Roamed earth in Mesozoicera
from lateTriassicup to
mid Jurassicperiod.
