Wumengosaurus

Naam beteken: “Wumeng lizard, named after the Wumeng Mountain area in China”1

Het geëet: VleisSeereptieleMiddel-TriasTegnies nie 'n dinosourus nie

Wumengosaurus was a small, long-bodied marine reptile that swam in the warm seas of what is now China during the Triassic Period. It had a long snout full of tiny, sharp teeth and probably hunted for small fish and shrimp. Even though it looked a bit like a dinosaur, it was actually a type of sauropterygian, a group that includes plesiosaurs.1 2

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

Wumengosaurus had a very long body with short legs, making it look a bit like a swimming lizard.2

Its jaws were long and pointed, like a pair of tweezers, and held more than 45 tiny teeth.1

Scientists think Wumengosaurus was one of the earliest and most basic members of the eosauropterygian group, which later gave rise to the huge plesiosaurs.1 2

The first fossil of Wumengosaurus was found in the Guanling Formation, a layer of rock that was once the bottom of a shallow sea.1 3

A second species, Wumengosaurus rotundicarpus, was named in 2021 based on a fossil from Panzhou District in Guizhou.1

Wumengosaurus lived about 247 to 241 million years ago, during the Middle Triassic, not long after the biggest mass extinction in Earth's history.1 3

KI-prent van Wumengosaurus — 'n KI-prent van hoe Wumengosaurus 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: Wumengosaurus
Benoem deur: Jiang et al. 20084
Groep: Seereptiele
Familie / klade: Eosauropterygia4
Klassifikasie: Sauropterygia4
Ouderdom van die rotse: 247 tot 241 miljoen jaar ()4
Rotsformasies: Guanling4
Lande: China4
Fossielrekords: 2 in The Paleobiology Database4
Ontdekking: Wumengosaurus was first described by scientists Jiang, Rieppel, Motani, and others in 2008, based on a fossil skeleton from the Guanling Formation in Guizhou, China.1 3
Steeds omstrede: Scientists are not sure exactly where Wumengosaurus fits on the family tree. Most studies place it as a basal eosauropterygian, but one study suggested it might be more closely related to ichthyosaurs.1
