Cryopterygius
Extinct genus of reptiles / From Wikipedia, the free encyclopedia
Cryopterygius (meaning 'frozen fin' in Greek) is an extinct genus of ophthalmosaurid ichthyosaur known from the uppermost Jurassic of Central Spitsbergen, Norway. The type species, Cryopterygius kristiansenae , is known from a single, but largely complete specimen from the Slottsmøya Member of the Agardhfjellet Formation (middle Volgian/late Tithonian, Late Jurassic). With a total length of 5–5.5 metres (16–18 ft), it is a large ichthyosaur.[1] A second species, C. kielanae, was found in the Kcynia Formation from the Late Jurassic of Poland. It is smaller than the type species, with a length of 3.5–4 metres (11–13 ft).[2]
It has been suggested that this article be merged into Undorosaurus. (Discuss) Proposed since December 2023. |
