Lower Cretaceous Pterosaurs

The Lower Cretaceous Period started about 136 million years ago when there was a dramatic change in the types of species of pterosaurs.  Very few pterosaurs made the transition from the Jurassic to the Cretaceous and a distinct new range of larger pterosaurs evolves at this time.  The main stages in the United Kingdom are as follows.

Upper Albian

Middle Albian

Lower Gault & Red Chalk

Upper Aptian

Lower Aptian

Barremian

Hauterivian

Valanginian

Berriasian (south) or
        Ryazanian (east)

Upper Gault, Upper Greensand, Cambridge Greensand, Hunstanton Red Rock

Lower Gault and Red Chalk

Gault-Greensand Junction and Upper Folkston Beds

Lower Greensand, Ferruginous Sands and Lower Folkston Beds

Lower Greensand, Atherfield Clay and Ferruginous Sands

Wealden Beds, Weald Clay and Upper Tealby Clay

Wealden Beds, Tealby Series
Upper Hastings Series and Claxby Ironstone

Wealden Beds, Lower Hastings Series and Lower Claxby Series

Upper Purbeck Beds, Durlston Beds

There are a vast number of specimens of pterosaur bone from the Cambridge Greensand, mainly of Ornithocheirid species.  Some specimens are of very large pterosaurs, but they are fragmentary.  The Cambridge Greensand is a derived sediment and it is likely that most of the pterosaur fossils come from a slightly earlier age.  The Purbeck beds have also yielded some pterosaur remains.

There are a great number of pterosaurs worldwide attributed to this time from a number of very good sites.  The Santana formation in Brazil, The sites in Xinjiang Province, China and Western Mongolia to name but three.
