Middle Jurassic Pterosaurs
The Middle Jurassic period in the United Kingdom shows very few pterosaur remains. There are a lot of dispersed individual sediments with local names. The main sediment groups are as follows.
The Stonesfield Slate of Oxfordshire is the main pterosaur bearing sediment in this period within the United Kingdom. This sediment contains a wide variety of individual bones and fragmentary remains of several types of pterosaurs including Rhamphocephalus, Pterodactylus, Dimorphodon, and other unidentified types. Several indeterminate fossils are lumped under the name of Rhamphocephalus.

between the two maps shown.
