Anurognathus was a tiny pterosaur and a cousin of the dinosaurs. Its body was very small (9 cm) compared with its extensive wings (50 cm) and it had a stubby tail. Anurognathus was a specialised insectivore and had a compact 2 cm head full of needle-like teeth. Its short, deep skull was characteristic of the primitive pterosaurs. In time they evolved longer and thinner heads.
