Fun facts
Kryptodrakon is the oldest known pterodactyloid pterosaur, meaning it had a long wing finger that made it a better flyer than earlier pterosaurs.2
Its name means 'hidden dragon' because it was discovered in a remote part of China and its fossils were hidden in rocks.1
Kryptodrakon lived in a river environment, which is unusual because many pterosaurs lived near the sea. This suggests it was adapted to life on land.2
The wing metacarpal bone of Kryptodrakon shows a mix of old and new features, with a primitive top part and a more advanced bottom part.2
Scientists think Kryptodrakon was an adult when it died because its shoulder and wrist bones were fused together.2
