Which Autobot Dinobot transforms into a pteranodon?

Which Autobot Dinobot transforms into a pteranodon? Swoop does. He is the Dinobot whose alternate mode is based on the pteranodon, a prehistoric flying reptile rather than a dinosaur in the strict scientific sense.

Swoop belongs to the original Generation 1 Dinobot team alongside Grimlock, Slag, Sludge, and Snarl. In the animated continuity, the Dinobots were created by Wheeljack and Ratchet after research into dinosaur fossils inspired their forms. Swoop was introduced in the 1985 episode “War of the Dinobots.”

The most common mix-up is confusing Swoop with the other Dinobots’ animal modes. Grimlock transforms into a Tyrannosaurus, Slag into a Triceratops, Sludge into a Diplodocus-like sauropod, and Snarl into a Stegosaurus. Swoop’s wings, beak, and flight capability make him the clear aerial specialist.

Different Transformers continuities redesign characters, and some use slightly different prehistoric identities or names. In the classic Autobot lineup, however, Swoop and the pteranodon mode are the canonical pairing.
