The Pterodactyl, often a synonym for Pterosaurs, refers to a group of flying reptiles that lived during the Mesozoic Era, about 228 to 66 million years ago. These prehistoric creatures were not dinosaurs, but a distinct group of reptiles closely related to them. Characterized by their winged structure, Pterodactyls had wings formed by a membrane of skin, muscle, and other tissues stretching from their elongated fourth finger to their bodies. They varied greatly in size and shape, with some having wingspans as large as airplanes.

Pterodactyls inhabited diverse environments, from coastal regions to inland areas, indicating a wide range of dietary habits and lifestyles. Their evolution showcases a significant adaptation for flight, with lightweight bones and aerodynamic bodies. Pterodactyls represent a remarkable example of the diversity of life forms in prehistoric times, particularly among reptiles adapted for flight.
