Anarosaurus

Het geëet: VleisSeereptieleMiddel-TriasTegnies nie 'n dinosourus nie

Anarosaurus was a small, swimming reptile that lived in the sea during the Middle Triassic, about 247 to 241 million years ago. It was not a dinosaur, but a cousin of plesiosaurs, with flippers and a long tail.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

Anarosaurus was tiny, only about 50 to 60 cm (1.6 to 2.0 ft) long, smaller than a modern cat.1

It had two different species: Anarosaurus pumilio and Anarosaurus heterodontus, which had different tooth shapes.1

The name Anarosaurus means 'without lizard' in Greek, but scientists are not sure why it was given that name.1

Anarosaurus lived in a shallow sea that covered parts of Europe during the Triassic, and its fossils are found in rocks that were once seafloor.1

The first fossil of Anarosaurus was found in Germany, but the original specimen was lost or destroyed during World War II.1

Anarosaurus is a pachypleurosaur, a group of small, primitive sauropterygians that were ancestors of the giant plesiosaurs.1

KI-prent van Anarosaurus — 'n KI-prent van hoe Anarosaurus 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: Anarosaurus
Benoem deur: Dames 18902
Groep: Seereptiele
Familie / klade: Pachypleurosauridae2
Klassifikasie: Sauropterygia2
Ouderdom van die rotse: 247 tot 241 miljoen jaar ()2
Rotsformasies: Vossenveld, Jena2
Lande: Nederland, Duitsland2
Fossielrekords: 4 in The Paleobiology Database2
Ontdekking: Anarosaurus was named by German paleontologist Wilhelm Dames in 1890, based on fossils found in Germany. The type species is Anarosaurus pumilio.1 2
Steeds omstrede: Scientists are still debating exactly how Anarosaurus swam and what it ate, because its skeleton is incomplete and some fossils were lost.1
