Beyond the game

The real Drepanosaurus

Drepanosaurus unguicaudatus had a specialized forelimb and a strongly curved tail tip. Its anatomy made this small reptile look unlike a conventional lizard.

The enlarged hand claw and unusual limb joints form a distinctive grasping apparatus. Together with the hooked tail, they distinguish this reptile from an ordinary lizard.
