Utuntu dushimishije

Elbretornis is known from only one partial skeleton, including a left humerus and parts of the wing and leg.1

It lived during the Maastrichtian age, the very end of the Cretaceous Period, just before the dinosaurs went extinct.1 2

The name Elbretornis honors the El Brete fossil site in Argentina, where many ancient birds have been found.1

Elbretornis was a ground-dwelling bird, and scientists think it was a good runner.2

It was about the size of a modern pigeon, measuring 33 cm (13 in) long and weighing around 570 g (20 oz).1

Some scientists wonder if Elbretornis might actually be the same as another bird from the same site, like Lectavis or Yungavolucris, but Elbretornis was smaller.1

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