Thunderclap

Thunderclap is an antagonist of the upcoming film The Good Dinosaur. He is a Nyctosaurus and the leader of a ferocious gang of Pterodactyls.

Official Bio
"The Pterodactyls are a search-and-"rescue" team of five. They like to sit back and let the often-treacherous storms in this part of the world do their dirty work, then reap the benefits of the devastation. But when these flying hunter-scavengers set their sights on Spot and Arlo, they’re in for a big surprise.

Trivia

 * The other three members of Thunderclap's gang are each a different species: Caulkicephalus, Guidraco, and Ludodactylus.
 * Real Nyctosaurus do not have teeth or wing claws like Thunderclap does.
