Pterodactyls died out along with the dinosaurs and many other animal and plant species during the K-T extinction event. It is believed that an asteroid, along with other environmental changes, struck the Earth and contributed to the mass extinction. Dinosaurs, pterosaurs, and many marine reptiles were not able to cope, so they went extinct.
