Utuntu dushimishije
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
