Liaoceratops

名字的意思： “Liaoning horned face”1

吃：植物角龍類白堊紀早期

Liaoceratops was a small, early horned dinosaur that lived in what is now China. It had a beak like a parrot and a small frill on its head, but no big horns yet. This little plant-eater helps scientists understand how later horned dinosaurs like Triceratops evolved.2 1

酷東西

趣味知識

Liaoceratops is one of the oldest and most primitive neoceratopsians, meaning it was an early relative of horned dinosaurs like Triceratops.2

Only two nearly complete skulls of Liaoceratops have been found, and one of them belonged to a juvenile.1 2

It lived about 127 to 121 million years ago during the Early Cretaceous period.1

Liaoceratops had a small frill at the back of its skull, but it did not have the large horns that later ceratopsians had.2

Its name comes from Liaoning, the province in China where its fossils were discovered.1

Scientists think Liaoceratops shows that some features of later horned dinosaurs evolved piece by piece, not all at once.2
