Yayitya: IzityaloIzitya-zityalo ezinemilomoiJurassic yokuqala

Archaeocursor was a tiny, speedy plant-eater that lived in what is now China. It was one of the earliest beaked dinosaurs in Asia, and it was only about as long as a big dog!1

izinto ezimnandi

Iinyani ezimnandi

1

Archaeocursor is known from just one fossil: a nearly complete left thigh bone (femur) that is 93 millimetres long.1

2

It lived during the Early Jurassic period, about 199 to 184 million years ago, in the Sinemurian to Pliensbachian stages.3

3

Scientists think Archaeocursor was a young adult when it died, because of the growth rings in its thigh bone.1

4

This dinosaur is the oldest ornithischian (beaked plant-eater) ever found in Asia.1

5

Archaeocursor was about the same size as Eocursor, another early ornithischian from South Africa.1

6

Its name means 'ancient runner from Asia', because it was built for speed with long legs.1

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

Eyona mibuzo ibuzwa kakhulu: Archaeocursor

?How big was Archaeocursor?

About 1 metre (3.3 feet) long, which is roughly the size of a big dog.21

?What did Archaeocursor eat?

It was a plant-eater, like other ornithischian dinosaurs.2

?When did Archaeocursor live?

It lived during the Early Jurassic period, about 199 to 184 million years ago.21

?Why is it called Archaeocursor?

Its name means ancient runner because it was an ancient dinosaur built for speed.2

Ukufunyanwa
Archaeocursor was named in 2025 by a team of scientists including X. Yao, Q. Zhao, T. Ren, G. Wei, and X. Xu. The single fossil was found near a subway station in Chongqing, China.31
Kusaxoxwa ngayo
Scientists are not sure exactly how Archaeocursor is related to other early ornithischians. The family tree shows it as the earliest-diverging ornithischian in Asia, but this is not strongly supported.1
