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.
