The Bull was a Tyrannosaurus rex that lived on Isla Sorna in 2001. He briefly encountered the rescue party led by Alan Grant before coming face-to-face with the Spinosaurus, where he was ultimately killed in the ensuing fight.
The Bull was born sometime before 2001 on Isla Sorna. The exact origin of this individual is unknown. The rescue party stumbled upon him feasting on a dead Parasaurolophus, after which he chased them away. While chasing the humans, he met the Spinosaurus, a fight between the two ending with his death when the Spinosaurus snapped his neck with its jaws.
This Tyrannosaurus was similar in appearance to the Tyrannosaur Buck from The Lost World: Jurassic Park, although this individual had brighter green coloration, especially when it came to the CGI model. According to ILM's Jurassic Park III Comparative Size Chart, the Bull reached a length of 11.3 meters (37 feet), a height of 4.4 meters (14.5 feet), and Glen McIntosh stated his weight was 8 tons (16,000 pounds).
- The animatronic for this T. rex was the same model used for the Tyrannosaur Buck. It was reskinned and slightly updated by Stan Winston Studio.
- A common fan theory persists that this T. rex was Junior from The Lost World: Jurassic Park, however, Matt Winston shot this theory down during the 2015 Jurassic Party.
- The maquette for the Bull shows a key difference between him and the second film's male T. rex. The Bull had stripes going down his arms, whereas the Buck did not.
- Despite being commonly passed off as fact in discussions, the Bull being a "sub-adult" or "juvenile" is unsupported by any official material from the franchise, and in fact is contradicted by both the third film's script where he is described as "fully grown" and the ILM size chart as he is not noted to be anything other than an adult animal (compared to the juvenile Pteranodon on the same chart).
