吃：魚飛行爬蟲類白堊紀晚期嚴格來說不是恐龍

Saraikisaurus was a flying reptile that lived at the very end of the Age of Dinosaurs. It soared over what is now Pakistan, hunting fish with its beak-like jaws. Even though it looked like a dinosaur, it was actually a pterosaur, a cousin of the dinosaurs.1 1

趣味小知識：翼龍在恐龍頭上飛來飛去，但牠們是恐龍的親戚，不是恐龍喔。

趣味知識

Saraikisaurus lived between 72 and 66 million years ago, during the Maastrichtian stage of the Late Cretaceous.1

Its fossils were found in the Vitakri Formation in Pakistan, a rock layer that was once a river floodplain.1

The only known fossil of Saraikisaurus is a lower jaw bone (mandible), which tells scientists it was a fish-eater.1

Saraikisaurus belongs to a group of pterosaurs called Pterodactyloidea, which includes many large, short-tailed flying reptiles.1

The name Saraikisaurus honors the Saraiki people and language of central Pakistan.1

Saraikisaurus was a pterosaur, not a dinosaur. Pterosaurs were flying reptiles that lived at the same time as dinosaurs.1
