Pterodactylus (151-149 mya)

Pterodactyl is one of the most famous representatives of the ancient flying reptiles, or pterosaurs. These reptiles lived during the Jurassic Period and became the first vertebrates to conquer the sky long before the appearance of birds. Pterosaurs are divided into two major groups: rhamphorhynchoids and pterodactyloids. Pterodactyl belonged to the latter. It lived about 155–145 million years ago in what is now Germany, which at that time was covered by a warm shallow sea.

Pterodactyl had a light and graceful body adapted for flight. Its head was relatively small, but its elongated jaws gave it a distinctive profile. Its brain was not especially large, but the cerebellum—the region responsible for coordinating movements—was well developed, helping it maneuver in the air. The bones of its skeleton were hollow, like those of modern birds, keeping the animal lightweight and capable of sustained flight.

The forelimbs of Pterodactyl had four digits. Three short ones were used for walking on land or climbing rocks and branches, while the fourth—long and composed of several phalanges—supported the wing. The flight membrane consisted of three parts: the main section stretched from the elongated finger to the hind limbs, a smaller section connected the elbow to the shoulder, and another linked the hind limbs with the tail. This structure made flight both stable and flexible.

Pterodactyls were relatively small, with a wingspan of only about one meter. They lived in colonies along marine coastlines, where food was abundant. Their diet consisted mainly of fish and large insects, which they skillfully caught in the air or near the water’s surface.
