Abstract: | Early Jurassic pterosaurs are rare and display low diversity with only three well known genera for a period of ∼21 million years duration. The Hettangian-Pliensbachian Dimorphodon reached a wingspan estimated at only 1.3 m, while the Lower Toarcian forms Dorygnathus and Campylognathoides reached wings spans of 1.8 m. Here we describe a new specimen of Toarcian pterosaur from the north east coast of England that may have achieved an estimated wingspan between 1.6 and 3.2 m. |
