  1. 1. ANTONIO SAORÍN 1ºB Ardipithecus
  2. 2. ARDIPITHECUS  Ardipithecus is a fossil genus of primate hominid found in Ethiopia that is considered descendants of Orrorin tugenensis and direct ancestors of the australopithecines
  3. 3. SPECIES  There are two species of Ardipithecus described: a. ramidus, and a. kadabba,
  4. 4. SKULL  they moved in a bipedal manner. The size of its brain was similar to the great apes current

  7. 7. HABITAT The recent works on Ardipithecus ramidus, a 4.4 million years old hominin found at Middle Awash, Ethiopia, provided critical information about the early part of human evolution. However, habitat characterization of this basal hominin has been highly contested. Here we present new sedimentological and stable isotopic (carbon and oxygen) data from Aramis, where the in situ, partial skeleton of Ar. ramidus (nicknamed 'Ardi') was excavated. These data are interpreted to indicate the presence of major rivers and associated mixed vegetations (grasses and trees) in adjacent floodplains. Our finding suggests that, in contrast to a woodland habitat far from a river, Ar. ramidus lived in a river-margin forest in an otherwise savanna (wooded grassland) landscape at Aramis, Ethiopia. Correct interpretation of habitat of Ar. ramidus is crucial for proper assessment of causes and mechanisms of early hominin evolution,
