Stelladens

Naam beteken: “star tooth”1

Het geëet: VleisMosasourusseLaat KrytTegnies nie 'n dinosourus nie

Stelladens was a marine lizard that lived in the sea during the time of the dinosaurs. Its teeth were shaped like stars, with sharp ridges that no other sea reptile had. Scientists are still trying to figure out what it ate!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

Stelladens lived about 72 to 66 million years ago, at the very end of the Age of Dinosaurs.3

Its teeth had 2 to 4 sharp, serrated ridges on the inside, like little star blades. No other animal, alive or extinct, has teeth like this.2

Stelladens was about 5 metres (16 feet) long, as big as a small boat.1

The only fossils found so far are a piece of jaw and two teeth. That is enough to know it was a new kind of mosasaur.2 1

Stelladens belonged to a group called Mosasaurinae, which includes some of the biggest sea lizards ever.3 2

Its teeth were short and strong, good for crushing, not just stabbing like other fish-eaters.2

KI-prent van Stelladens — 'n KI-prent van hoe Stelladens 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: Stelladens
Benoem deur: Longrich et al. 20234
Groep: Mosasourusse
Familie / klade: Mosasauridae4
Klassifikasie: Mosasauroidea4
Ouderdom van die rotse: 72 tot 66 miljoen jaar (Maastrichtian)4
Rotsformasies: Couche III4
Lande: Marokko4
Fossielrekords: 1 in The Paleobiology Database4
Ontdekking: Stelladens was named by Nick Longrich and his team in 2024. The fossils were found in a phosphate mine in Morocco.1 3
Steeds omstrede: Scientists are not sure what Stelladens ate. Its star-shaped teeth are unlike anything seen before, so its diet remains a mystery.2
