Pterosaurs A-Z

Actinofibril   The fibre found in pterosaurs’ wings. Several layers of actinofibrils stretched across the wings, stiffening them, thus making flying easier.  

Anurognathus   A small pterosaur from the Triassic Period. With a wingspan of 35 centimetres (14 inches), it was the smallest known pterosaur. It had a short tail, long skull and sharp, pointed teeth. It probably ate insects. 

Dimorphodon   A small pterosaur from the Early Jurassic Period with a long, pointed tail and wingspan of 1.4 metres (4.6 feet). Like all members of the rhamphorhynch family, it had a disproportionately large head, which was also deep and narrow like a puffin’s. For a male, the size and colouring of its head may have played a crucial role in impressing a female during courtship.
