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

Prettige feite

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

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

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

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

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

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

Vir dino-kenners

Wetenskaplike naam: Archaeocursor
Benoem deur: Yao et al. 20253
Groep: Plantvreters met snawels
Familie / klade: Ornithischia3
Klassifikasie: Ornithischia3
Ouderdom van die rotse: 200 tot 184 miljoen jaar (Sinemurian / Pliensbachian)3
Rotsformasies: Ziliujing3
Lande: China3
Fossielrekords: 1 in The Paleobiology Database3
Ontdekking: 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.3 1
Steeds omstrede: 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
