Leiodon

Naam beteken: “smooth tooth”1

Het geëet: VleisMosasourusseLaat KrytTegnies nie 'n dinosourus nie

Leiodon was a giant marine lizard that swam in the warm seas of the Late Cretaceous. It had smooth, curved teeth perfect for grabbing slippery fish and other sea creatures.1

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

Leiodon was first named by the famous scientist Richard Owen in 1841, based on just two tooth fragments and a bit of jawbone.1

The name Leiodon means 'smooth tooth' because the fossil teeth had a smooth and polished surface.1

Leiodon lived between about 100 and 66 million years ago, during the Late Cretaceous period.3

Leiodon fossils have been found all over the world, including in Antarctica, Europe, Africa, and South America.3

Some scientists think Leiodon might not be a valid genus because its main fossil teeth are now lost, making it a 'nomen dubium' or doubtful name.1

Leiodon was one of the original genera used to define the family Mosasauridae in 1853.1

KI-prent van Leiodon — 'n KI-prent van hoe Leiodon 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.

Mite-breker

Mite: Leiodon was a dinosaur.

Waarheid: Leiodon was not a dinosaur. It was a mosasaur, a type of giant marine lizard that lived in the ocean.1

Vir dino-kenners

Wetenskaplike naam: Leiodon
Benoem deur: Owen 18423
Groep: Mosasourusse
Familie / klade: Mosasauridae3
Klassifikasie: Mosasauroidea3
Ouderdom van die rotse: 100 tot 66 miljoen jaar (Cenomanian / Maastrichtian)3
Rotsformasies: López de Bertodano, Gramame, Opoka3
Lande: Sirië, Antarktika, Brasilië, Swede, Pole, Duitsland3
Fossielrekords: 18 in The Paleobiology Database3
Ontdekking: Richard Owen named Leiodon in 1841 from two tooth fragments and a small jaw piece found in Essex, England.1
Steeds omstrede: Scientists are not sure if Leiodon is a valid genus because the original tooth fossils are missing, so it might be a 'nomen dubium' (doubtful name).1
