Pterodactyl, Serious Sam Wiki

The Pterodactyl is a flying enemy that appears in Serious Sam: Double D and Serious Sam: Double D: XXL. The Pterodactyl leisurely flies around in a set pattern. When it hits the end of its patrol, it will switch and fly in the opposite direction until it hits the end of that patrol, then will go back in the original direction it was moving, and so on. They cannot be harmed by any weapons. Pterodactyls first appear in Flying Reptiles, and only remain in the Jurassic era levels. In Dino Switcheroo
