Rinchenia was a small, bird-like dinosaur that lived in the Late Cretaceous period. It had a big, bony crest on its head like a cassowary, and it probably used its beak to eat plants, eggs, and small animals.1 2

酷東西

趣味知識

Rinchenia was first thought to be a type of Oviraptor, but later scientists decided it was different enough to be its own genus.1

Its tall, hollow crest on top of its skull is like a cassowary's helmet, and may have been used for display or making sounds.1

Rinchenia lived about 72 to 66 million years ago in what is now the Gobi Desert in Mongolia.3 2

The skull of Rinchenia is complete, but only pieces of the rest of the skeleton have been found, so scientists have to guess what it looked like based on similar dinosaurs.1 2

Rinchenia was a small dinosaur, about 1.7 to 2.5 metres long, and weighed around 25 kilograms.1 2
