Protoceratops — the small Mongolian ceratopsian that changed what we knew about dinosaur ancestry

When and where

Protoceratops lived in what is now Mongolia and northern China during the Late Cretaceous, between 75 and 71 million years ago. Fossils come mainly from the Djadokhta Formation of the Gobi Desert, a site famous for preserving dinosaurs in their final poses.

How we know

In 1923, American Museum of Natural History expeditions led by Roy Chapman Andrews recovered the first known Protoceratops skeletons from the Flaming Cliffs of Mongolia. The type species, P. andrewsi, was named that same year. A second and larger species, P. hellenikorhinus, was described in 2001 from the Bayan Mandahu Formation in China. For decades, palaeontologists treated Protoceratops as a likely ancestor of Triceratops and the ankylosaurians. Later discoveries of more primitive protoceratopsids showed it sat further down the branch than once thought. Source: https://en.wikipedia.org/wiki/Protoceratops

What set it apart

Protoceratops was small by ceratopsian standards — roughly 1.8 metres long and perhaps 70–100 kilograms. It had a distinctive bony frill at the back of the skull and a small nose horn, though far less dramatic than the horns of its later relatives. Its beaked jaws were built for cropping tough vegetation. The well-preserved Gobi fossils include skeletons, eggs, and even nests, making it one of the most completely known dinosaurs of its size.

For collectors and classrooms

A detailed Protoceratops figurine works well for collectors who want to move beyond the famous giants. Models highlight the frill and compact build that make this animal so recognisable. Browse Protoceratops figures on Amazon
