Vastatosaurus rex

Vastatosaurus rex is the evolutionary descendant of Tyrannosaurus rex and is the apex predator of Skull Island. Its black color helps it warm up in the sun.

Size, Speed, and Strength
The Vastatosaurus rex is 15-21 meters (50-70 ft) long, 5.63-7.88 meters (18.75-26.25 ft) tall, and weighs 7.27-18.18 tonnes (8-20 tons). It has no special powers or weaknesses, but can run up to 40.23 km/h (25 mph) and has animal-level intelligence. It can use its teeth, claws, and tail as weapons during fights. The Vastatosaurus rex possesses osteoderms on its head and back and has three fingers on its hand unlike its ancestor.

Ecology, Habitat, and Behavior
Adults of the species normally live in open areas while juveniles can be found in the dense jungle. They will eat any meat, whether it was killed by them, another Vastatosaurus rex, or something else. Vastatosaurus rexes mark their territory using urine. They are extremely territorial, and will fight any creature that enters its territory. They prefer ambushing their prey to chasing and killing it.
