The creature reappears in Son of Kong, crying out as the island is sinking. A large two-legged lizard – This reptilian creature climbs up a vine from the crevasse to attack Jack Driscoll. It falls back into the pit when Jack cuts the vine it is climbing. Other than the two limbs, the other distinct feature of this creature is the iguana-like ridge of spikes down its back. Orville Goldner said it was loosely based on the features of the Desmatosuchus. In Peter Jackson's re-creation of the "spider pit sequence", it is among the monsters eating the sailors who survived the fall. This creature would inspire the Monsterverse's Skullcrawlers Tyrannosaurus – A great dinosaur which tries to eat Ann, but is fought and killed (or, at least, overpowered) by Kong, who breaks its jaw open. The dinosaur was modeled after Charles R. Knight's depiction of a Tyrannosaurus. However, 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 not discovered 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 cancelled 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. The 1932 King Kong screenplay refers to the dinosaur only as a "Meat Eater". Elasmosaurus – A highly stylized, serpentine aquatic reptile with a long neck and tail as well as two pairs of flippers. It inhabits the bubbling swamp area inside King Kong's cave. Goldner describes the Tanystropheus as "being designed as more slender than the ones known to science, and its swimming limbs are less prominent. It battles Kong in the style of a giant, constricting snake. It also attempts to eats Hellstrom as he attempts to flee at the end of Son of Kong. The 'snapping' version that grabbed Hellstrom was actually the revamped Brontosaurus from the original film; the same holds for the armature version seen briefly snarling in predatory glee. Pteranodon – It menaces Ann and is the first
