Pterosaurs

Name means: Winged lizard
Ranges is size from a sparrow to an airplane

Pterosaurs are a group of flying reptiles that evolved in the Late Triassic and went extinct at the end of the Cretaceous. They were the first vertebrates to fly, sharing the sky with the early birds. The Pterosaurs were very diverse in size ranging from sparrow-sized to that of small airplane (30 foot wing span). Their wings were like no other flying vertebrate -- supported by an elongated fourth finger on the hand. Membranes connected the end of the wing to the body.

Some Pterosaurs had very large heads with crests and beaks. Others had many teeth. New specimens from the Early Cretaceous of China show that some Pterosaurs were covered in small hair-like structures.
