Spinosaurus
Meet the star of Jurassic Park 3:Spinosaurus! Seriously, though, he was nothing like he was in the movie. Or at least that's what my brother says. He says it only ate fish and Giganotosaurus was bigger. He's right about the fish part, but not the Gignotosaurus part. He just can't accept fact that Spinosaurus was really the biggest theropod discoverd. It could grow to a length of 50 feet long, be 18 feet high, and weigh 3 tons.
