izinto ezimnandi

Iinyani ezimnandi

Chaoyangsaurus is the earliest known ceratopsian, or horned dinosaur, that scientists have found.2

Its skull was only about 14 centimetres long, about the size of a large apple.1

It had a beak made of horn on its upper jaw, with four bumps on the cutting edge.1

Chaoyangsaurus had two pointy teeth in the front of its upper jaw, called premaxillary teeth.1

The name Chaoyangsaurus went through several spellings before it was officially published in 1999.1

Its fossils were found in the Tuchengzi Formation, which is about 150 to 145 million years old.1 2

Umfanekiso owenziwe yi-AI: Chaoyangsaurus — Umfanekiso owenziwe yi-AI obonisa indlela Chaoyangsaurus esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.
