Big for a Baryonyx, Rudy was larger even than the Tyrannosaurus Rex, one of the biggests 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. Scar-Eye is about half as big again and thus is aproximentaly 120ft long. His large size may be due to the Dinosaur World having more oxygen that the world above.
