Diandongosaurus
Diandongosaurus was a small marine reptile that swam in the warm seas of China during the Triassic Period. It had a long body and sharp teeth for catching fish. It was only about as long as a ruler!12

Сонирхолтой баримтууд
Diandongosaurus had a snout that was not pinched, and the part of its skull in front of the eye was longer than the part behind the eye.2
Its skull had a small opening on top (the supratemporal fenestra) that was smaller than its eye socket.2
The bones that form the forehead (frontals) and the top of the skull (parietals) were fused together into single pieces.2
Its collar bone (clavicle) had a forward-pointing projection, which is unusual.2
The toe bones (ungual phalanxes) of its hind feet were extremely flattened from top to bottom, possibly helping it paddle.2
The only known complete skeleton of Diandongosaurus was found in a famous fossil site called the Guanling Formation, which preserves many Triassic sea creatures.1

Домог няцаагч

- Scientists are not sure exactly how Diandongosaurus is related to other marine reptiles. Some studies suggest it might be a close cousin of both nothosaurs and pachypleurosaurs, but its exact place in the family tree is still debated.2
