Oksoko was a small, feathered dinosaur that lived in what is now Mongolia. It had only two fingers on each hand, which is very unusual for a meat-eating dinosaur. Oksoko probably used its beak to eat plants and small animals.2 5

Utuntu dushimishije

Oksoko had only two functional fingers on each hand, a rare feature among theropod dinosaurs.2

Fossils of at least six Oksoko individuals have been found, some preserved together in a resting pose with their heads tucked under their arms.2

Oksoko lived about 72 to 66 million years ago, during the Late Cretaceous period.5

The name Oksoko comes from a three-headed eagle in Altaic mythology, because the main fossil block contains three skulls.1 2

Oksoko was a type of oviraptorid, a group of feathered dinosaurs that were close relatives of birds.2

The specific name avarsan means 'rescued' in Mongolian, because the fossils were confiscated from poachers.1 2

Ishusho ya Oksoko yakozwe na AI — Ishusho yakozwe na AI yerekana uko Oksoko 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.

Biracyagibwaho impaka: Scientists are still debating why Oksoko's arms became so reduced, and whether it used its two-fingered hands for foraging, nesting, or display.2
