Eotephradactylus
Eotephradactylus was a seagull-sized flying reptile that lived about 209 million years ago in what is now Arizona, USA. It had a long jaw full of teeth and probably ate fish with tough, armor-like scales.12

Datu dibertigarriak
Eotephradactylus is one of the oldest pterosaurs ever found in North America.2
Its jawbone was discovered inside a block of rock that was being prepared in a lab, not in the field.1
The tips of its teeth were worn down, which suggests it chewed on hard fish scales or shells.1
It lived in a hot, drying part of the supercontinent Pangaea, near the equator.1
The same bonebed where Eotephradactylus was found also contained one of the world's oldest turtle fossils.2
Its name comes from Greek words meaning 'dawn', 'ash', and 'wing', because it was found in volcanic ash.1
