Balaenognathus was a flying reptile that lived about 150 million years ago. It had a strange, spoon-shaped snout with hundreds of tiny hooked teeth. It used its beak like a strainer to scoop up tiny shrimp from the water, just like a modern flamingo.1 2

ເລື່ອງໜ້າຮູ້ມ່ວນໆ

Balaenognathus had at least 480 teeth, more than most other pterosaurs.1

The tips of its teeth had tiny hooks, which have never been seen in any other pterosaur. These hooks helped trap shrimp so they couldn't escape.1 2

The front of its snout was shaped like a spatula and had no teeth, so water could flow in easily.1

Its upper jaw was more curved than its lower jaw, so its mouth stayed slightly open at the front even when closed.1

The fossil was found by accident in a quarry in Germany, inside a block of stone that also contained bones of a crocodile-like animal.1 2

Balaenognathus lived during the Late Jurassic period, about 152 to 149 million years ago.3

It had long legs, which helped it wade through shallow seas while feeding.2
