Protarchaeopteryx was a turkey-sized dinosaur covered in feathers, but it could not fly. It lived in China about 124 million years ago and was probably a fast runner.1

izinto ezimnandi

Iinyani ezimnandi

Protarchaeopteryx had long, vaned feathers on its tail, but because the feathers were symmetrical, scientists think it could not fly.1

Its bones were hollow like a bird's, and it had a wishbone.1

It had three fingers with sharp, curved claws on each hand.1

Some scientists think it might have climbed trees and used its feathered arms to parachute down.1

Its name means 'before Archaeopteryx', but it actually lived later than Archaeopteryx, in the Cretaceous period.1

The only known skeleton is a partial one, kept at the Geological Museum of China.1

Umfanekiso owenziwe yi-AI: Protarchaeopteryx — Umfanekiso owenziwe yi-AI obonisa indlela Protarchaeopteryx esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

ubuzile

Eyona mibuzo ibuzwa kakhulu: Protarchaeopteryx

?How big was Protarchaeopteryx?

It was about 1 metre (3.3 ft) long, or possibly as small as 0.7 metres (2.3 ft), and weighed around 1.6 kilograms (3.5 lb). That's about the size of a turkey.1

?Could Protarchaeopteryx fly?

No, it could not fly. Its tail feathers were symmetrical, like those of modern flightless birds, and its skeleton could not support flapping flight.1 3

?What did Protarchaeopteryx eat?

It was probably a herbivore or omnivore, though its hands looked like those of small meat-eating dinosaurs.1

?Did Protarchaeopteryx have feathers?

Yes, it had well-developed, vaned feathers on its body, arms, and a fan on its tail. The feathers were symmetrical, which is why it couldn't fly.1 3

Inyaniso ngeentsomi

Intsomi: Because it had feathers, some people think Protarchaeopteryx could fly like a bird.

Inyaniso: Its feathers were symmetrical and its body was too heavy for flapping flight, so scientists believe it was flightless.1

Kusaxoxwa ngayo: Scientists are not sure exactly where Protarchaeopteryx fits in the dinosaur family tree. Some think it is an early oviraptorosaur, while others think it is closer to birds.1
