Upper Triassic Pterosaurs

The Triassic Period represents the start of the Mesozoic Era and started about 225 million years ago, continuing until about 190 million years ago.  In the United Kingdom this Period is divided into three sub divisions.

Rhaetic

Keuper

Bunter

Langport Beds, White Lias. (Upper)
Cotham Beds. (Upper)
Westbury Beds, Contorta Shales and Bone Beds. (Lower)

Sully Beds, Grey Marls, Tea Green Marls,
Red Marls, Sandstones.

Upper Mottled Sandstone.
Pebble Beds
Lower Mottled Sandstone.

Triassic Pterosaur remains are very rare in the United Kingdom.  There are a few fragmentary remains from the Rhaetic Bone Beds consisting of individual or partial bones.  These fossils are of uncertain classification and no real attempts have been made to associate them with known species.  All of the known remains are of rhamphorhynchoid species.  A few remains show similarities with later Dimorphodontid bones.

World wide, the best Triassic remains come from the Zorzino Limestone of Cene, near Bergamo in Italy and from the Preon Valley.  There are also fragmentary remains from other sites.

Eudimorphodontidae

Eudimorphodon ranzii	Two fine specimens from the Zorzino Limestone of Cene, near Bergamo in Italy.  One is kept at Bergamo and the other in Milan.  The Milan specimen is probably a juvenile animal.
Eudimorphodon rosenfeldi	Specimen from the Late Triassic (Middle Norian) of North eastern Italy.
Eudimorphodon comptonellus	Small species from Greenland.
Eudimorphodon from Texas	Upper jaw fragment with two teeth, from the Dockum Formation, West Texas, U.S.A.  Classification is uncertain.
Eudimorphodon from Luxembourg	Teeth from the Rhétien deposits of Syren, Grand Duchy of Luxembourg.
Eudimorphodon from Austria	Partial skull bones and long bones from Austria
Caviramus schesaplenensis	Lower jaw from the Northern Calcareous Alps of Switzerland

Dimorphodontidae

Peteinosaurus zambelli

Skeletal remains of two separate specimens from the Middle to Upper Norian Zorzino Limestone of Cern, near Bergamo in Italy.

Rhamphorhynchidae

Preondactylus buffarinii	Specimen from the Upper Triassic, Early to Middle Norian of Madonna Peraries in the Preon Valley of Udine, Italy.  This species is known from a skeletal specimen and a specimen within a gastric pellet from a carnivorous fish.  This represents the earliest identifiable pterosaur so far discovered (1989).
Preondactylus sp.	Upper Triassic, Middle to Upper Norian from the Zorzino Limestone, Endenna, near Bergamo, Italy.
Austriadactylus cristatus	Upper Triassic crested pterosaur from Austria.

Indet Species 

Raeticodactylus filisurensis

Primitive non-pterodactyloid pterosaur from Switzerland, with a distinct head crest and multi cuspate teeth.
