Carinodens

Igama lithetha: “keel teeth”1

Yayitya: InyamaIimosasauriiCretaceous yamvaNgokwenene ayisiyo dayinaso

Carinodens was a small mosasaur, a marine lizard that lived in the late Cretaceous seas. It had round, blunt teeth like a set of nutcrackers for crushing hard-shelled animals. At only about 2 to 2.6 metres long, it was one of the tiniest mosasaurs ever.1

izinto ezimnandi

Iinyani ezimnandi

Carinodens was first thought to be a crocodile! A fossil jaw was originally named Bottosaurus belgicus and considered a crocodilian before being recognized as a mosasaur.1

Its teeth were very different from each other. The front teeth were round and curved, while the back teeth were flat and blade-like with a keel on each side.1

Scientists can tell what Carinodens ate by looking at tiny scratches on its teeth. The wear patterns show it munched on hard-shelled animals that lived on the seafloor.1

Carinodens is closely related to Globidens, another mosasaur with crushing teeth. Together they belong to a group called Globidensini.1

The name Carinodens means 'keel teeth' because its teeth have a ridge like the keel of a boat. It replaced the older name Compressidens, which was already used for a different animal.1

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

ubuzile

Eyona mibuzo ibuzwa kakhulu: Carinodens

?What did Carinodens eat?

Carinodens ate hard-shelled animals like clams, oysters, and sea urchins. Its blunt teeth were perfect for crushing them, and scratches on the teeth show it munched on creatures that lived on the seafloor.1 2

?How big was Carinodens?

Carinodens was about 2 to 2.6 metres (6.6 to 8.5 feet) long. That makes it one of the smallest mosasaurs ever.1

?Where did Carinodens live?

Carinodens lived in the late Cretaceous seas, and its fossils have been found in Europe, North America, South America, and North Africa. Most skull fossils come from the Netherlands and Belgium.1

?Is Carinodens a dinosaur?

No, Carinodens is not a dinosaur. It is a marine lizard called a mosasaur that lived in the sea during the time of the dinosaurs.1

Kwiingcali zeedayinaso

Igama lenzululwazi: Carinodens
Inikwe igama ngu:: Thurmond 19693
Iqela: Iimosasauri
Usapho / iclade: Mosasauridae3
Ukuhlelwa: Mosasauroidea3
Ubudala bamatye: 72 ukuya ku-66 izigidi zeminyaka (Maastrichtian)3
Izakhiwo zamatye: Maastricht, Gramame, Bereza Beds3
Amazwe: iNetherlands, iMorocco, iBrazil, iUkraine, iRashiya, iBhelgiyam3
Iirekhodi zeefosili: 16 kwi-Paleobiology Database3
Ukufunyanwa: The first fossils were found in Belgium and described by Louis Dollo in 1913 as Globidens fraasi. In 1969, J.T. Thurmond gave it the new name Carinodens because the old name was already taken.1
Kusaxoxwa ngayo: Scientists are not sure how many species of Carinodens existed. Some think C. belgicus and C. fraasi might be the same species, while others believe they are different based on tooth shape.1
