Upper Cretaceous PterosaursThe Upper Cretaceous period was the last of the Mesozoic ages, terminating in a mass extinction at about 65 million years ago. This age saw the largest of the pterosaurs and some species have been found world wide. The United Kingdom main stages for this period are as follows. |
|---|
| Maastrichtian | Upper Chalk and Trimmingham Chalk (Lower Maastrichtian) |
|---|---|
| Senonian | Upper Chalk and Norwich Chalk |
| Turonian | Middle Chalk |
| Upper Cenomanian | Plenus Marls and basal Melbourne Rock |
| Middle Cenomanian | Lower Chalk and Chalk Basement Beds |
| Lower Cenomanian | Chalk Marl and various local beds |
The Upper Cretaceous Stages in the United Kingdom are essentially the Chalk of Southern England. There are a good variety of pterosaur remains of species like Ornithocheirus and Ornithostoma. Other species are known from fragmentary evidence.
World wide, the large pterosaurs like the Pteranodontids and Azhdarchids are widely found along with many other smaller species.
