count-your-change: "I think all th eArdi parts were found at one spot."

As I read it, there were two different species of Ardipithecus -- ramadus (4.4 million years) and kadabba (5.6 million years) -- discovered in at least three different locations, and including at least eleven individuals.

Here (on left) are some of the ramadus bones and (on right) kadabba:

Thanks for the clarification. As I look at that partial skeleton I wonder how anyone could draw conclusions about how it moved even if it were one individual. No knee joints, no hip joints, a crushed pelvis that was assembled and reassembled until it was “just right”, no ribs or spine....yet somehow out of this hodge podge an Ardi hobbles forth.
