The Pterodactyls are supporting antagonists in The Good Dinosaur. They are a group of nasty scavengers hailing from various species of pterosaur, all named after a storm aspect. Collectively, they are led by Thunderclap.
"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."
Coldfront (voiced by Steven Clay Hunter) is a Ludodactylus. His gray crest curves upwards and is distinguished by his pink neck.
Frostbite is a Ludodactylus. He is the brother of Coldfront. He has a purple crest that is shaped like a triangle.
Windgust is a Guidraco. He has the smallest crest, but the thickest beak and neck.
The Good Dinosaur
After an Apatosaurus named Arlo is stranded far away from his home, the Pterosaurs encounter him while looking for prey following a deadly storm. Thunderclap and the other Pterosaurs introduce themselves under the claim that they are a rescue patrol and agree to help him find his way back. However, they quickly reveal their carnivorous nature, and detect that Arlo has something accompanying him and pressure him into revealing where his acquaintance is. While Arlo tricks Downpour and Coldfront to look for it, Arlo escapes with his human Spot and runs from the Pterosaurs. The Pterosaurs are hot on their trail until they run into two young Tyrannosaurus named Nash and Ramsey, who scare the group away.
When the two return to the mountains, the Pterosaurs encircle them like sharks and attack Arlo, managing to kidnap Spot and push Arlo off a cliff while he is distracted. Spot escapes their grasp briefly and hides inside a stump at the river while the Pterosaurs try to claw him out. Arlo arrives and traps two of them under a tree and hits the others into the water, where they ride helplessly downstream. It is unknown what became of them afterwards, but it's likely that they either drown, got caught in rapids or washed ashore and don't follow the storm anymore.
