2253. Rudy

Rudy is an massive Baryonyx (or possibly Suchomimus) that lived in an underground world during the Ice Ages, who appears in Ice Age: Dawn of the Dinosaurs as the main antagonist. He is also Buck's nemesis. He appears in the video game of the same name, where his role is exactly the same as in the movie.
Rudy was a giant Baryonyx that had pursed the weasel named Buck in the past, his attempts having left a lasting impression on Buck, who had since revered Rudy as a worthy opponent. Rudy, like most other dinosaurs, didn't speak the language of other animals, though had no need to, as he could easily be read by his actions and the expressions on his face. He eyed all other creatures that he encountered as prey. Vicious in nature, Rudy was constantly on the hunt and quick to attack others. Some creatures were brave enough to attack Rudy , such as Buck and Momma.
He was very big for a Baryonyx, Rudy was larger even than the Momma Tyrannosaurus Rex, one of the biggest carnivorous dinosaurs ever. It is possible that he was a Suchomimus. Rudy speaks a language that consists of either loud growls or roars as most other dinosaurs usually did. Rudy had a long snout filled with sharp teeth, though the skin on the front of his snout was cracked, as Buck had knocked out one of his teeth, and his forearms were equipped with giant, clawed three-fingered hands. Rudy is often stated to be roughly 60ft long. However when compared to Manny or Ellie (who are each about 16-20ft long), he is roughly six times there size. also, in the commentaries to Ice Age 3, the filmmakers explicitly stated that Momma is twice as large as a real T.rex, about 80ft. Rudy is about half as big again and thus is approximately 120ft long. In Buck's story when Buck climbs up a high tree over the clouds it showed that Rudy had a fin, which supports the idea that Rudy is an Spinosaurus. However, if one looks closely in the same scene of Buck's story, it's actually Rudy's neck and back. The filmmakers also confirmed that Rudy is a Baryonyx. His large size may be due to the Dinosaur World having more oxygen that the world above.
