Re: Postosuchus stance
Hmmm... the proposed bipedalism of Postosuchus is too interesting...
Is there evidence that Lotosaurus, which is completely known according
to Nesbitt (2005) was bipedal?. In such a case, this may suggest
closer relations between Postosuchus and poposaurs than with other
rauisuchians, as proposed in one analysis of Nesbitt (2003).
