Сонирхолтой баримтууд
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
