Unenlagia was a feathered, bird-like dinosaur from Argentina. It could not fly, but its arms folded like a bird's wings. This raptor was one of the closest dinosaur relatives of modern birds.1

酷東西

趣味知識

Unenlagia had very long arms for a raptor and could lift them high, like a bird flapping its wings.1

Its hip and shoulder bones were shaped almost exactly like those of early birds such as Archaeopteryx.1

Unlike many other raptors, Unenlagia did not have a large sickle claw on its foot.4

Scientists disagree on whether Unenlagia was a dromaeosaurid or belongs to its own family, Unenlagiidae.2

The only fossils found so far are from a single individual: parts of the backbone, shoulder, hips and legs.4

It lived about 90 million years ago, which is later than many other bird-like dinosaurs.2

?Was Unenlagia a dinosaur?

Yes, Unenlagia was a theropod dinosaur, a type of raptor that lived in South America during the Late Cretaceous.3

?What did Unenlagia eat?

The sources do not say exactly what Unenlagia ate, but as a raptor it likely ate meat, like other dromaeosaurs.3

?Did Unenlagia have feathers?

Yes, Unenlagia was a feathered, bird-like dinosaur, as stated on the page.3

迷思破解王

迷思： Unenlagia is often called a 'bird dinosaur' that could fly.

真相： It could not fly, but its arms were built like a bird's and it may have used them for balance while running.1
