Keilhauia was a dolphin-like marine reptile that lived in the Early Cretaceous, about 145 million years ago. It had large eyes and a long snout, and swam in the shallow seas near what is now Norway. It was about as long as a small car!1

Ebyewuunyisa

Keilhauia is known from only one fossil, discovered in 2010 on the island of Spitsbergen.1

Its species name, nui, comes from the acronym of a Norwegian youth environmental organization called Natur og Ungdom.1

It had a wide top end of its ilium (hip bone) and a short ischiopubis compared to its thigh bone, which helps scientists tell it apart from other ichthyosaurs.1

Keilhauia is the most complete ichthyosaur known from the Berriasian age, the very beginning of the Cretaceous Period.1

Its pelvic girdle is the most complete one ever found from the Cretaceous Period.2

It lived in a shallow sea with an oxygen-poor seafloor, where cold seeps supported many invertebrates like ammonites and brachiopods.1

Kikyakubaganyizibwako ebirowoozo: Scientists are unsure exactly how Keilhauia is related to other ichthyosaurs because its skull is not well preserved, so its family tree position is uncertain.1

Buli kituufu ku lupapula luno kirina ennamba eraga ensibuko yaakyo. Bwe tuba nga tukoze ensobi, tusonyiwe, ffe tuli bawagizi ba dayinoso, so si magazini ya ssaayansi. Tubuulire ku [email protected] tujja kugitereeza.

Rex alumwa enjala! Dino Wiki pulojekiti ya taata eri mutabani we ayagala ennyo dayinoso, ya bwereere, tewali bulango era tewali bikulondoola. Abakulu basobola okuwa Rex akantu ak'okulya okuyamba okugikuuma ku mutimbagano.Liisa Rex
