Vastatosaurus rex is a large, unique tyrannosaurine tyrannosaurid from Skull Island, descended from Tyrannosaurus. It measures 40-50 feet long.
The biggest terrestrial predator on Skull Island is the V. rex. Like their prehistoric fellow tyrannosaurs, Skull Island V. rexes have little competition for their spot as top predators. In spite of their size, they can turn on a surprising burst of speed for short periods, clocking up to 25 mph for limited stretches in pursuit of prey.
