Tyrannosaurus rex was a dinosaur on Skull Island. It is also the dinosaur that Kong battled during Ann Darrow's experience on Skull Island in the original King Kong. Kong was out in the jungle when he heard Ann scream so he rushed over and fought the T. rex. Eventually, Kong overcame the carnivore, wrestled it to the ground and snapped its jaws killing it.


The Tyrannosaurus rex stood 3.66 metres (12 feet) tall at the hips, measered 12.3 metres (40 feet) in length, and weighed up to 10 tons. It was nearly the biggest known meat-eater, although the Giganotosaurus was the largest reaching lengths of 13.2 m. Mapusaurus and Carcharodontosaurus were both larger than T. rex.


The T. rex was modeled after Charles R. Knight's depiction of a Tyrannosaurus. There is some confusion, however, as to the name of this dinosaur as it possesses three fingers per hand, unlike Tyrannosaurus which had only two. However, the number of fingers in Tyrannosaurus was disputed at the time, as a complete manus was uncovered until the mid-1990s. In the documentary I'm King Kong! The Exploits of Merian C. Cooper, included on the 2 disk DVD release of King Kong, Cooper refers to this beast as an Allosaurus, not a Tyrannosaurus, which would help explain the number of fingers. However, the creature was originally intended to be a Tyrannosaurus designed for the canceled Willis O'Brien film Creation (1931). It may also be worth noting that the Tyrannosaurus present in Willis O'Brien's earlier project The Lost World (1925) also had a third finger. Thus, this dinosaur does indeed appear to be a T. rex.
