Description
The first group of vertebrates to take to the air as a way of life were the pterosaurs. These flying reptiles flew on wings made of skin, which were attached along the length of the greatly elongated, fourth fingers of each hand and rejoined the body at thigh level.
These flying reptiles evolved in Late Triassic times, some 70 million years before the first known bird, Archaeopteryx, appeared. They thrived throughout the Jurassic and early part of the Cretaceous, diversifying into many forms, among them the largest flying creatures of all time. Then the group began to decline, its last members becoming extinct at the end of the Mesozoic Era. Pterosaur remains have been found all over the world, except in Antarctica, mostly in marine deposits.
There are two sub orders of pterosaur. The earliest and most primitive types are the rhamphorhynchs; the later types include the more familiar flying reptiles - the pterodactyls.
The earliest known pterosaurs were already advanced flyers by the Late Triassic Period, 190 million years ago. They flourished worldwide until their extinction at the end of the Jurassic.
The pterodactyls are the most familiar of the flying reptiles. They were already established in Late Jurassic times, when their relatives, the rhamphorhynchs, became extinct. The pterodactyls continued through the Cretaceous, although only a few types survived to the end of that period.
These pterosaurs had the same general structure at the earlier rhamphorhynchs, but the tail was shorter, the neck longer and the skull more elongated.
The sub order Pterodactyloidea ranged from some of the smallest known pterosaurs to some of the largest flying vertebrates that ever lived.
