Datos curiosos
Pachagnathus is known only from a piece of its lower jaw, which is 61.5 mm long and very narrow.1
Its lower jaw has a strange ridge that switches between a single line and a pair of lines between the teeth. No other pterosaur has this.1
Pachagnathus lived far from the coast, in a dry inland area. Most early pterosaurs lived near the sea.1
It was named in 2022, making it a very recently discovered pterosaur.1
