Austriadactylus

A colored line drawing of the extinct early pterosaur Austriadactylus. It has a pointed snout with a bony crest along the top, toothy jaws, a fuzzy body, membranous wings with three small fingers at the wrist, short legs with the fifth toe supporting a small rear membrane, and a long thin tail ending in a vertical diamond-shaped rudder. It's depicted colored dark brown-black with white stripe markings, with a yellow crest and a yellow spot on its tail rudder.

Austriadactylus cristatus was an early pterosaur that lived during the Late Triassic, about 215 million years ago, in what is now Austria and Italy.

It’s one of the most basal (“primitive”) pterosaurs currently known, with its long tail lacking the stiffening bony rods seen in other early “rhamphorhynchoid-grade” forms.

It had a wingspan of around 1.2m (~2′), and a bony crest on its snout that grew taller towards the front. Its jaws contained a mix of two different tooth types – a few long pointed teeth and numerous smaller three-pointed teeth – with wear patterns that suggest its diet primarily consisted of hard-shelled invertebrates.
