Gorosaurus

Gorosaurus is a giant theropod dinosaur. He stands 35 meters tall and weighs 8000 tons in his first appearance and later 50 feet tall and weighed 20000 tons. This would suggest that Gorosaurus was still yung in his first appearance.

King Kong Escapes
Gorosaurus was living on Mondo Island. He saw Susan Watson and tried to devour her. Fortunately, King Kong appeared and fought Gorosaurus. He was knocked to the ground and each time he tried to stand Gorosaurus kicked him to the ground again. Finally Kong grabbed Gorosaurus' jaws and pried them open, breaking it and defeating the dinosaur.
