Foetodon

Foetodon are a lizard-species that live on the jungle floor on Skull Island. It is a huge animal.

Foetodon appeared in the film King Kong. It was the monstrous lizard eating the carcass of a dead dinosaur (possibly a Ligocristus), then a second one went for Ann. After chasing her inside a rotten log, the Foetodon fell prey to a Vastatosaurus Rex, and the first one escaped.
