Dimorphodon (“two-form tooth”) is a pterosaur believed to belong to the family Rhamphorhynchoidea from the Early Jurassic Period of southern England. The species is unique among pterosaurs because it has two types of teeth like that of a mammal.
Dimorphodon is one of the smallest species of pterosaur, with a wingspan of 1.5 metres. Like other pterosaurs, it is housed exclusively in an Aviary.
