Carentonosaurus

Naam beteken: “lizard from the Charente region of France”3 1

Het geëet: VleisMosasourusseLaat KrytTegnies nie 'n dinosourus nie

Carentonosaurus was a marine lizard that swam in warm, shallow seas during the time of the dinosaurs. It had a strange, heavy backbone that made it extra dense, like a living anchor in the water.1

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

Carentonosaurus had very thick, heavy bones in its back, a condition called pachyostosis, which helped it stay underwater without floating up.1

Its neck bones were not thickened, only the back bones were pachyostotic, which is unusual among marine lizards.1

This lizard lived about 100 to 94 million years ago, during the Cenomanian stage of the Cretaceous Period.3

Carentonosaurus fossils have been found in France, Portugal, and Spain, showing it lived in the warm Tethys Sea.2

It is part of a group called aigialosaurs, which are close relatives of the giant mosasaurs.3

The first fossils were discovered in western France, in rocks that were once a shallow, warm sea near a coast.1

KI-prent van Carentonosaurus — 'n KI-prent van hoe Carentonosaurus 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: Carentonosaurus
Benoem deur: Rage and Néraudeau 20043
Groep: Mosasourusse
Familie / klade: Aigialosauridae3
Klassifikasie: Mosasauroidea3
Ouderdom van die rotse: 100 tot 94 miljoen jaar (Cenomanian)3
Rotsformasies: La Cabaña, B3/C1, Tentúgal3
Lande: Frankryk, Spanje, Portugal3
Fossielrekords: 8 in The Paleobiology Database3
Ook bekend as: Carentonosaurus (ouer name tel nou as dieselfde dier)3
Ontdekking: Carentonosaurus was named by paleontologists Jean-Claude Rage and Didier Néraudeau in 2004, based on fossils found in the Charente region of France.3 1
Steeds omstrede: Scientists are not sure if Carentonosaurus lived only in the early part of the Late Cretaceous or if it also appeared in the early Cenomanian.1
