Catutosaurus was a fast-swimming marine reptile that lived in the Jurassic seas. It looked a bit like a dolphin but was actually an ichthyosaur, not a dinosaur. It had a long snout and strong flippers for chasing fish.1

Inyani emnandi: esi sirhubuluzi saselwandle sasiqubha ngelixa iidayinaso zazihamba emhlabeni. Wonke umntu uzibiza ngokuba ziidayinaso, kodwa zazilisebe elahlukileyo lezirhubuluzi.

Iinyani ezimnandi

Catutosaurus lived about 149 to 143 million years ago during the Late Jurassic period.2

Its fossils were found in the Vaca Muerta formation in Argentina, which is famous for its well-preserved marine reptiles.2

Catutosaurus had a mix of features: a skull like some ophthalmosaurids and a forefin like others, showing that these traits evolved separately.1

Its forefin had tightly packed polygonal bones and a broad connection between the upper arm and forearm bones.1

The name Catutosaurus comes from the Los Catutos area in Argentina where it was discovered.2

Catutosaurus is part of a group called ophthalmosaurids, which were the last ichthyosaurs to survive, living until about 94 million years ago.1

Umfanekiso owenziwe yi-AI: Catutosaurus — Umfanekiso owenziwe yi-AI obonisa indlela Catutosaurus esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

Igama lenzululwazi: Catutosaurus
Inikwe igama ngu:: Fernández et al. 20212
Iqela: Ii-ichthyosauri
Usapho / iclade: Ophthalmosauridae2
Ukuhlelwa: Ichthyosauria > Ichthyosauromorpha2
Ubudala bamatye: 149 ukuya ku-143 izigidi zeminyaka (Tithonian)2
Izakhiwo zamatye: Vaca Muerta2
Amazwe: i-Argentina2
Iirekhodi zeefosili: 1 kwi-Paleobiology Database2
Ukufunyanwa: Catutosaurus was named in 2021 by Marta S. Fernández, Lisandro Campos, Erin E. Maxwell, and Alberto C. Garrido. The fossils were found in the Los Catutos area of Patagonia, Argentina.2 1
Kusaxoxwa ngayo: Scientists are still debating exactly how Catutosaurus is related to other ophthalmosaurids. Its mix of features makes its place on the family tree unclear.1
