Prettige feite

Equijubus is one of the earliest known duck-billed dinosaurs, or hadrosauroids.1 2

Its name means 'horse mane' in Latin, because it was found near Mazong Mountain, which means 'horse mane mountain' in Chinese.1

The only known fossil of Equijubus includes a complete skull and parts of the backbone and hips.1

Grass microfossils found on an Equijubus specimen are among the oldest known grass fossils, and may be the oldest evidence of a dinosaur eating grass.1

Equijubus lived about 113 to 110 million years ago, during the Early Cretaceous period.3

Unlike many later duck-billed dinosaurs, Equijubus lacked a bony ridge over its eyes called a palpebral bone.1

Vir dino-kenners

Wetenskaplike naam: Equijubus
Benoem deur: You et al. 20033
Groep: Plantvreters met snawels
Familie / klade: Hadrosauroidea3
Klassifikasie: Ornithischia > Ornithopoda > Iguanodontia3
Ouderdom van die rotse: 113 tot 110 miljoen jaar (Albian)3
Rotsformasies: Zhonggou3
Lande: China3
Fossielrekords: 1 in The Paleobiology Database3
Ontdekking: Equijubus was named in 2003 by You Hailu and colleagues. The only fossil was found in the summer of 2000 by a Chinese-American expedition in the Gobi Desert of northwest China.1 2
Steeds omstrede: Scientists are not sure if Equijubus was a true hadrosauroid or a more primitive iguanodont. Some studies place it as the earliest hadrosauroid, but others think it might be outside that group.1
