Archaeoceratops was a small, primitive ceratopsian dinosaur that lived during the Early Cretaceous period in what is now north-central China. Despite its name meaning 'ancient horned face', this early member of the ceratopsian group actually lacked the impressive horns that would later characterise its famous relatives like Triceratops.
This diminutive dinosaur measured just 0.9 metres in length and weighed approximately 10 kilograms, making it one of the smaller ceratopsians known to science. Unlike its later four-legged cousins, Archaeoceratops walked on two legs and possessed a comparatively large head for its body size. The most distinctive feature was a small bony frill projecting from the back of its skull, representing an early stage in the evolution of the elaborate frills seen in later ceratopsians.
As a herbivore, Archaeoceratops would have fed on the ferns, cycads, and early flowering plants that grew in the warm, humid forests of Early Cretaceous China. Its beak-like mouth was well-suited for cropping vegetation, whilst rows of small teeth helped process plant material. The discovery of Archaeoceratops has provided valuable insights into the early evolution of ceratopsian dinosaurs, showing how this group developed from small, bipedal ancestors into the large, quadrupedal giants of the Late Cretaceous.
Archaeoceratops had a distinctive small bony frill at the back of its skull, despite lacking the horns typical of later ceratopsians. Its proportionally large head and bipedal stance set it apart from its four-legged descendants.
Archaeoceratops likely lived in small groups, foraging for low-growing vegetation in the forests of Early Cretaceous China. Its bipedal locomotion would have allowed it to move quickly through dense undergrowth when escaping from predators.

Archaeoceratops was first described by You Hailu and Dong Zhiming in 2002. The original fossils were discovered at Mazongshan Formation, Gansu Province, China.
