Liaodactylus was an early pterosaur that used its long jaws like a strainer. It had more than 150 thin, comb-like teeth to catch tiny creatures in the water. This flying reptile lived about 160 million years ago in what is now China.1

Liaodactylus is the oldest known filter-feeding pterosaur, living about 160 million years ago in the Late Jurassic.1

Its skull was only 133 mm long, but it held 152 teeth in total, arranged like a comb to trap food.1

The name Liaodactylus means 'Liaoning finger', after the province in China where it was found.1

Liaodactylus belonged to a group called Ctenochasmatidae, which were all filter-feeders with long snouts and many teeth.1

This pterosaur lived alongside small dinosaurs, mammals, and salamanders in the Yanliao Biota of China.1

Liaodactylus had a large opening in its skull called a nasoantorbital fenestra, which is a feature of advanced pterosaurs.1

Atosɛm sɛefoɔ

Atosɛm: Some people think all pterosaurs ate fish or meat.

Nokorɛ: Liaodactylus was a filter-feeder, straining tiny creatures from water with its comb-like teeth, not catching fish.1
