The Unidentified crocodilian was a species of crocodilian that only appeared in a scene cut from the film Jurassic World: Fallen Kingdom.
One identification proposed by fans is Deinosuchus, as InGen did have genetic material of the animal by 2015. However, the skeleton is way too small for an adult Deinosuchus, though it could've been a juvenile. Another identification is Brachychampsa. However, the skeleton is larger than the real animal, though InGen could've manipulated its genetic code to make it larger. Another identification is Crocodylus or Alligator, due to how similar it looks in terms of size and snout width, although it could be a load of species of extant or extinct crocodilian. Alternatively, it could simply be a prop for athomosphere, a la Disneyland's Jungle Cruise or Jurassic Park River Adventure.
