Utuntu dushimishije
Colymbosaurus lived from about 168 to 113 million years ago, during the Jurassic and Cretaceous periods.5
It belonged to a group called Cryptoclididae, which were plesiosaurs with long necks and small heads.1
There were at least two valid species: Colymbosaurus megadeirus and Colymbosaurus svalbardensis.1
Colymbosaurus trochanterius is not considered a valid species, but some fossils are still referred to Colymbosaurus.1
Fossils have been found in the Kimmeridge Clay Formation in the UK, which was a shallow sea at the time.1
Colymbosaurus was actively mobile and lived in the water, likely swimming near the surface.5
