Compressidens

Naam beteken: “compressed teeth”1

Het geëet: VleisMosasourusseLaat KrytTegnies nie 'n dinosourus nie

Compressidens was a small mosasaur, a marine lizard that lived in the sea during the time of the dinosaurs. It had special flat teeth for crushing hard-shelled animals like clams and sea urchins.1 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

Compressidens is now called Carinodens, because the name Compressidens was already used for a different animal, a type of mollusk.1

It was one of the smallest mosasaurs, only about 2 to 2.6 metres (6.6 to 8.5 feet) long.1

Its teeth were flat and compressed from side to side, which is why it was named Compressidens, meaning 'compressed teeth'.1

Only the back five teeth were used for crushing food; the front teeth were small and pointed for grabbing prey.1

Fossils of Compressidens have been found in Europe, North America, South America, and North Africa.1

Scientists think it may have lived in deep water most of the time, only rarely coming into shallow seas.1

KI-prent van Compressidens — 'n KI-prent van hoe Compressidens 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: Compressidens
Benoem deur: Dollo 19242
Groep: Mosasourusse
Familie / klade: Mosasauridae2
Klassifikasie: Mosasauroidea2
Ouderdom van die rotse: 72 tot 66 miljoen jaar (Maastrichtian)2
Rotsformasies: Craie de Ciply2
Lande: België2
Fossielrekords: 1 in The Paleobiology Database2
Ontdekking: The name Compressidens was given by Louis Dollo in 1924, but it was later changed to Carinodens in 1969 because the name was already taken.1 2
Steeds omstrede: Scientists are not sure what the upper jaw of Compressidens looked like, because no fossils of the upper jaw have been found.1
