Sorry about the doubt I have not to be about dinosaurs, but just occurred to me... the head of _Dsungaripterus_ (a pterosaur) has some strange features, like the small crest over its head and a small spike pointed backward on the back of the head. But what really bothered me was his 'beak' (if it can be called so...) some teeth on the back half of the jaws, and on the front half, just a strange 'beak' curved upside... So, what may have been the function of this 'beak' and his diet?
And, by the way, what is the difference between _Huayangosaurus_ and _Kentrosaurus_, because I think they're in someway simillar to each other, or its just a 'dream' of mine? And are there any simillarities between _Liliensternus_ and _Dilophosaurus_?
Thanks for any help,
