Key Differences
Pterodactyls lived during various periods, including the Jurassic and possibly earlier, whereas Pteranodons existed specifically during the Late Cretaceous period. This difference in geological timeframes means that they would not have coexisted. Additionally, Pteranodons were typically larger than what people generally think of as Pterodactyls.

Linguistically, the term "Pterodactyl" is derived from the Greek words for "wing" and "finger," describing their wing structure. Pteranodon comes from Greek words meaning "wing" and "toothless," highlighting its lack of teeth. Both terms are nouns in the English language, and they often appear in scientific and popular discussions about prehistoric life.

In terms of physical features, Pterodactyls generally lacked the large crests that are a hallmark of Pteranodons. The Pteranodon is notable for its large, backward-pointing crest, which is believed to have been used for stabilization during flight. Pterodactyls, being a broad category, exhibited a wider range of physical traits.

Pterodactyl is a colloquial term often applied to various types of pterosaurs, flying reptiles that lived during the time of the dinosaurs. Pteranodon, on the other hand, is a specific genus of pterosaur that existed during the Late Cretaceous period. The term "Pterodactyl" is often used inaccurately to describe all pterosaurs, while "Pteranodon" refers to a particular species with well-defined characteristics.
