Stelladens

Igama lithetha: “star tooth”1

Yayitya: InyamaIimosasauriiCretaceous yamvaNgokwenene ayisiyo dayinaso

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

Inyani emnandi: esi sirhubuluzi saselwandle sasiqubha ngelixa iidayinaso zazihamba emhlabeni. Wonke umntu uzibiza ngokuba ziidayinaso, kodwa zazilisebe elahlukileyo lezirhubuluzi.

izinto ezimnandi

Iinyani ezimnandi

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

Umfanekiso owenziwe yi-AI: Stelladens — Umfanekiso owenziwe yi-AI obonisa indlela Stelladens esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

Igama lenzululwazi: Stelladens
Inikwe igama ngu:: Longrich et al. 20234
Iqela: Iimosasauri
Usapho / iclade: Mosasauridae4
Ukuhlelwa: Mosasauroidea4
Ubudala bamatye: 72 ukuya ku-66 izigidi zeminyaka (Maastrichtian)4
Izakhiwo zamatye: Couche III4
Amazwe: iMorocco4
Iirekhodi zeefosili: 1 kwi-Paleobiology Database4
Ukufunyanwa: Stelladens was named by Nick Longrich and his team in 2024. The fossils were found in a phosphate mine in Morocco.1 3
Kusaxoxwa ngayo: Scientists are not sure what Stelladens ate. Its star-shaped teeth are unlike anything seen before, so its diet remains a mystery.2
