was an interesting find as it was the first rhomaleosaurid pliosaur
be discovered outside of Europe. Rhomaleosaurids like
Yuzhoupliosaurus were long necked pliosaurs that
between the plesiosaurs like Plesiosaurus,
and the shorter necked,
large skulled forms like Simolestes
Yuzhoupliosaurus itself would have likely been a
predator of fish and
possibly other small vertebrates which it could catch with the pointed
teeth in its mouth before swallowing them whole.
Yuzhoupliosaurus was named after the ancient city of Yuzhou which today is known as Chungking (also sometimes spelled Changquin). Other members of the rhomaleosuridae that Yuzhoupliosaurus is similar to are Macroplata, Maresaurus, Meyerasaurus and of course the type genus Rhomaleosaurus.
