     I just rechecked, and verified that the holotype of Sahelanthropus was indeed restricted to the cranium (including upper teeth).  The right mandible is specifically referred to as a paratype.  I am also now even more convinced that I was correct in removing Sahelanthropus from Hominidae and placing it in Pongidae in my recent classification posted here on August 8th of this year (see below).

     As I said then, Ardipithecus and/or Orrorin may slip back into Hominidae if bipedality is confirmed, but I now suspect Sahelanthropus may have branched off even earlier (before Pan; perhaps as a sister group to Gorilla).   Whether the paratype mandible will remain with Sahelanthropus or end up elsewhere in Pongidae, I have no idea at this point.  As always, more fossils are needed.  Before I formally move Sahelanthropus above Pan, I need to see how it compares to Gorilla (as well as Samburupithecus).
