I think it may be Ichthyosaurus itself or Shonisaurus for a bigger and more immpressive animal. Shonisaurus had a rather minute dorsal fin, hardly the size of the one in the image. I think we should think about the marine reptiles that are about the size of an average submarine. I know, but as we all know, the raptors  are featherless, Dilophosaurus had venom, T. rex can only see movement, Spinosaurus  is a land predator, and Pteranodon  in the third movie had teeh throughout the series. They could've both make the Ichthyosaurus larger and give it a sail-like dorsal fin.
