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

1

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

2

Its skull had a small opening on top (the supratemporal fenestra) that was smaller than its eye socket.2

3

The bones that form the forehead (frontals) and the top of the skull (parietals) were fused together into single pieces.2

4

Its collar bone (clavicle) had a forward-pointing projection, which is unusual.2

5

The toe bones (ungual phalanxes) of its hind feet were extremely flattened from top to bottom, possibly helping it paddle.2

6

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

Wothetsa nthano zabodza

Nthano: Some people might think Diandongosaurus was a dinosaur because it lived long ago and had a long tail.

Zoona: Diandongosaurus was not a dinosaur. It was a marine reptile called an eosauropterygian, a group that includes ancestors of plesiosaurs.1

Diandongosaurus was named in 2011 by Chinese paleontologists Qing-Hua Shang, Xiao-Chun Wu, and Chun Li. They described it from a complete, articulated skeleton found in the Guanling Formation of Yunnan Province.12

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
