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

1

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

2

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

3

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

4

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

5

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

Mafunso ofunsidwa kwambiri okhudza 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.12

?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

Kupezeka
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
Akukambiranabe
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
