Re: What are the biggest highlights of modern paleontology?
Rescued from truncation:
Well, the Eunotosaurus "comeback" is highly questionable to some (if
> you mean as a turtle ancestor).
I know all molecular phylogenies continue to be against it (though the
latest study I've seen is surprisingly inconclusive on this topic* and
on Lissamphibia). But has the anatomy of *Eunotosaurus* been questioned?
The trunk ribs are pointed (indicating loss of the sternum), have the
same number as in turtles, and are fused to plates of dermal bone that
immobilize the trunk... and on the other side, there's still no trace of
a cleithrum in any crown-group diapsid.
* The reason may be that, as usual, there's no tuatara in the data matrix.
