Description
Pterosaurs were the first reptiles to develop powered flight. They lived for a long time, from the Late Triassic to the End of the Cretaceous (228-66 million years ago). Although they are sometimes referred to as ‘flying dinosaurs,’ this is incorrect. Although they are closely related to dinosaurs, they are technically just outside of the group, so paleontologists refer to pterosaurs ad dinosaurs as ‘sistergroups’.
- Characteristics: Unlike birds, which have wings mostly made of feathers, the wings of pterosaurs are made of skin, more like a modern bat. However, the skin membrane of the bat’s wing is supported by four really long fingers. A pterosaur wing has only one long finger supporting its leading (front) edge. So, although the pterosaur wing and bat wing are superficially similar, they are quite different under the skin. Pterosaurs lived on earth for a long time, so there are many different kinds.
- Size and Color: This model is 4 inches long and 7 inches wide. It is medium brown with a lighter colored head.
