Document Summary
17 fossil fragments that were different enough to warrant creating a new genus type. 1994- 90 fragments found representing 45% of a skeleton. Foramen magnum is more forward than in apes/bipeds. Most apelike hominid ancestor known (to date) Root of teeth is vertical as in later hominids, but enamel is thicker than apes of ardipithecus. Leg bones of those of a biped. Toe bone shows angle at the joint indicating a toe-off stride (biped) Fairly complete though distorted cranium and mandible. Flat face, tall, vertically oriented cheek area, no depression behind brow ridges. More evidence is needed with the same set of features. Features of the head/ of the femur are said to be bipedal. This would be 2 million years earlier that the earliest existing evidence for bipedalism. Other authorities disagree and question if the form is a hominid. Toumai hope of life in local goran language. Small canines of hominid size, shape, and wear pattern.
