Good to know someone has worked on *Dianchungosaurus*.

Nitpicking alert!:

You are right that *Askeptosaurus* is a thalatto_saur_ -- but it's not a 
crocodile in the widest sense. You mean the thalatto_suchians_ 
(*Steneosaurus*, *Metriorhynchus*, *Geosaurus*, that sort of thing).

-is is both masculine and feminine. -e is neutral, and this is correct 
because Greek keras is neutral, too. The other species must therefore be *S. 
breve*... as in fact it is.
