They likely couldn't put themselves on beaches indeed, with a marine body like that... but I still wonder about the head. Predators like crocodiles have a rather moveable neck and they CAN upright their heads when they need to. So, why not a crocodile-like animal like a tylosaurus? A moveable neck would have helped a predator like this one catching swift preys like fishies...
Tylosaurus wasn't croc-like, it was a big monitor lizard. And it probably didn't spend a lot of time'swiftly' chasing fish. At 10-15metres long, they would have been going after (somewhat) less maneuverable prey like other reptiles and much larger fish (the one we have on display here had a small mosasaur in its stomach). And no, it's neck vertebrae would not allow it to raise its head in an S, anymore than an elasmosaur could.
OK, you made your point. However, I compared tylos with crocs, not with 76-neck-vertebrated elasmosauruses!
yeah it's a shame that Papo messed up the Tylosaurus as being in Seal mode heh, yes it could move it's head around but no way in like the post of a seal could I guess. It's neck vertebrae would never allow it to do that, it's neck is also too short to allow this
Here another good photo indicating that such a pose won't even be possible for Tylosaurus and any other Mosasaur
Tylosaurus was half Monitor half serpent, it's body and looks are more Monitor like as where it's unhingable jaws make it also the forefather of the Serpents
However it's behavior may have been like that of an Estuarine Crocodile though, thanks for this cool Tylo topic, I love this! ;D ;D ;D
