Pterosaur Timeline
| Upper Cretaceous | This time has the biggest pterosaurs like Pteranodon and Quetzalcoatlus. There are very few small pterosaurs and birds are becoming more common. | |
| Cretaceous | ||
| Lower Cretaceous | Large numbers of short tailed pterosaurs dominate the skies. Dsungaripterus, Ornithocheirus and Tapejara are characteristic of this age. | |
| Upper Jurassic | During this period,
Pterodactylus and Rhamphorhynchus are the dominant species.
The long tailed and short tailed pterosaurs are living side by side. |
|
| Jurassic | Middle Jurassic | Rhamphorhynchus and
Rhamphocephalus are long tailed species. they appear to be quite
rare at this time. Pterosaur remains are seldom preserved. |
| Lias | Many new species of long tailed
pterosaur are evolving. Dimorphodon and Dorygnathus show
development in the jaws and wings of pterosaurs. |
|
| Triassic | Upper Triassic | Primitive long tailed pterosaurs like Eudimorphodon are rare. They have teeth with three cusps and strong skeletons. |
