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

Ishusho ya Eternauta yakozwe na AI — Ishusho yakozwe na AI yerekana uko Eternauta ishobora kuba yari isa, yakozwe na mudasobwa hashingiwe ku byo abahanga bazi. Ni ugukeka gusa: inyamaswa nyayo ishobora kuba yari isa ukundi, kandi nta muntu uzi amabara yayo nyayo.

Ivumburwa: 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
Biracyagibwaho impaka: Scientists are still debating exactly how Eternauta is related to other ichthyosaurs, because different computer analyses give different family trees.1
