Dianmeisaurus
Dianmeisaurus was a tiny, slender marine reptile that swam in warm seas during the Middle Triassic, about 245 million years ago. It had a long body and a small head with big eyes, and it probably hunted small fish and shrimp in the water.23

Datos curiosos
Dianmeisaurus was very small, with a total body length of less than 50 centimetres (about 20 inches).3
It had 41 vertebrae in its neck and back before the hips, which is a lot for such a small reptile.3
Its eyes were very large compared to the openings behind them on the skull, helping it see in dim water.3
The space between its eyes was extremely narrow, a feature that helps scientists tell it apart from similar reptiles.21
Dianmeisaurus lived alongside two other small marine reptiles in the same ancient sea: Diandongosaurus and Dianopachysaurus.3
The second species, Dianmeisaurus mutaensis, was named in 2024 and its skeleton probably came from a young animal.1
Its front leg bones (the ulna) were wider at the top than at the bottom, which is unusual.3

- The first species, Dianmeisaurus gracilis, was named by Shang Qinghua and Li Chun in 2015 based on a nearly complete skeleton from Luoping, Yunnan, China. A second species, D. mutaensis, was added in 2024 by Hu, Li and Liu.213
- Aínda en debate
- Scientists are still debating whether Dianmeisaurus is more closely related to European pachypleurosaurs or to the nothosauroid group of marine reptiles.3
