Thalassomedon

Naam beteken: “sea lord”1

Het geëet: VleisPlesiosourusseLaat KrytTegnies nie 'n dinosourus nie

Thalassomedon was a huge marine reptile that swam in the seas of North America about 95 million years ago. It had an extremely long neck, over half its body length, and used its sharp teeth to catch fish and other prey.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

Thalassomedon's neck had 62 vertebrae and was about 5.9 metres (19 feet) long, more than half of its total body length.1

Its flippers were about 1.5 to 2 metres (4.9 to 6.6 feet) long, helping it steer through the water.1

Stones have been found in the stomach area of Thalassomedon, which scientists think may have helped grind food or acted as ballast for diving.1

Its skull was only 47 centimetres (19 inches) long, but its teeth were 5 centimetres (2 inches) long.1

Thalassomedon lived during the Cenomanian stage of the Late Cretaceous, about 95 million years ago.1

Its closest relative is Elasmosaurus, another long-necked plesiosaur.1

Six specimens of Thalassomedon are on display in museums across the United States.1

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