Prehistoric crocodile, no. But besides size, modern-day crocodilians (crocodiles and alligators) are almost the same.
300 feet long

Dienonychus was a raptor, similar in appearance to the Velociraptor. It is unlikely that any are alive today.
A prehistoric marine reptile, the largest of the Pliosaurs and they were like a 60 foot crocodile with flippers.
Its a draw between 2 species, Deinosushus and Sarcosushus where both equal in size:the Deinosushus was the prehistoric alligator, it grew 40 ft long and weight 9 tonthe Sarcosushus (supercroc) was the prehistoric crocodile, it grew 42 ft and 10 tonon average the supercroc seems a bit larger though
No, there are no more prehistoric animals alive on earth. All animals alive today are decendents of prehistoric animals.
The boar crocodile was a large prehistoric crocodile that was like a boar in aggression and built. It had large tusks on the center of its jaw used for fighting other boar crocodiles. The boar crocodile rises itself and opens its deadly jaw when it sees dinosaurs comming to its territory. Scientists said that the boar crocodile had really large teeth, measuring lengths of 6 inches long. The boar crocodile lived in wetlands and clear swamps of the Mississippi and Tennessee.

Most animals alive today, except for some domestic breeds, existed in prehistoric times so, that makes most animals prehistoric. Pandas have been around since before humans learned to write. A close relative is the raccoon, which also has been around since before humans learned to write.
Sebek had the head of a crocodile, and was actually the representation of the crocodile himself (not the other way around).
I'm not sure what you mean by prehistoric mammal. Prehistoric usually means 'before recorded history' which means before writing. Writing has only been around for about 5000 years, which is much less than the time mammals have been around. They first appeared more than 200 million years ago. Even fairly late developments like the emergence of modern humans from earlier hominids happened around 200 000 years ago. So really all mammals are prehistoric.
There are 170,000 in the world today ..............
