Dianmeisaurus

Naam beteken: “beautiful lizard from Dian (an old name for Yunnan, China)”1

Het geëet: VleisSeereptieleMiddel-TriasTegnies nie 'n dinosourus nie

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.2 3

Prettige feit: hierdie seereptiel het geswem terwyl dinosourusse op land geloop het. Almal noem hulle dino's, maar hulle was 'n ander tak van die reptiele.

Prettige feite

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.2 1

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

KI-prent van Dianmeisaurus — 'n KI-prent van hoe Dianmeisaurus dalk gelyk het, deur 'n rekenaar gemaak uit wat wetenskaplikes weet. Dit is 'n raaiskoot: die regte dier het dalk anders gelyk, en niemand weet wat sy regte kleure was nie.

Vir dino-kenners

Wetenskaplike naam: Dianmeisaurus
Benoem deur: Shang and Li 20154
Groep: Seereptiele
Familie / klade: Pachypleurosauria4
Klassifikasie: Sauropterygia4
Ouderdom van die rotse: 247 tot 241 miljoen jaar ()4
Rotsformasies: Guanling4
Lande: China4
Fossielrekords: 2 in The Paleobiology Database4
Ontdekking: 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.2 1 3
Steeds omstrede: Scientists are still debating whether Dianmeisaurus is more closely related to European pachypleurosaurs or to the nothosauroid group of marine reptiles.3
