Eternauta was a fast-swimming marine reptile that lived in the ocean during the Late Jurassic. It had a long snout and big eyes to hunt small, slippery prey like fish and squid.1 5

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

Iinyani ezimnandi

Eternauta is named after a character from an Argentine science fiction comic called The Eternaut, which means 'the eternal traveler'.1

Its skull shows it had a special jaw that could open and close very fast, perfect for catching quick prey.1

Eternauta had a large scleral ring in its eye, which helped it see in dark, deep water.1

This ichthyosaur lived in the same sea as other marine reptiles like Caypullisaurus, but it ate different food to avoid competition.1

The only known fossil of Eternauta includes a nearly complete skull, a rib, and a front flipper.1

Eternauta belongs to a group of ichthyosaurs called ophthalmosaurids, which had very large eyes.1 2

Umfanekiso owenziwe yi-AI: Eternauta — Umfanekiso owenziwe yi-AI obonisa indlela Eternauta 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: Eternauta
Inikwe igama ngu:: Campos et al. 20255
Iqela: Ii-ichthyosauri
Usapho / iclade: Ophthalmosauridae5
Ukuhlelwa: Ichthyosauria > Ichthyosauromorpha5
Ubudala bamatye: 145 ukuya ku-143 izigidi zeminyaka (Tithonian)5
Izakhiwo zamatye: Vaca Muerta5
Amazwe: i-Argentina5
Iirekhodi zeefosili: 1 kwi-Paleobiology Database5
Ukufunyanwa: The fossil was first found in the Vaca Muerta Formation in Argentina and was originally thought to be a different ichthyosaur. In 2025, scientists Lisandro Campos and colleagues named it Eternauta patagonica.1
Kusaxoxwa ngayo: Scientists are still debating exactly how Eternauta is related to other ichthyosaurs, because different computer analyses give different family trees.1
