Venatosaurus

Venatosaurus (Furious Hunter-lizard) was a species of pack-hunting bipedal dinosaurs native to Skull Island. Several venatosaurs caused a brontosaur stampede while attempting to prey upon them. During the ensuing chaos, the venatosaurs began targetting members of Jack Driscoll and Carl Denham's search party, pursuing them up the side of a cliff as they tried to escape. The predators killed several brontosaurs and at least one member of the search party, Denham's cameraman Herb.
