izinto ezimnandi

Iinyani ezimnandi

Mei is one of the smallest known troodontid dinosaurs, about the size of a modern pigeon.1

The name Mei means 'sleeping one' in Chinese, because the fossil was found curled up with its head tucked under its arm, just like a sleeping bird.1

Mei lived during the Early Cretaceous period, about 125 to 120 million years ago.2

This dinosaur had feathers and was a close relative of birds.1

The sleeping posture of Mei shows that this behavior, common in modern birds, evolved before birds themselves appeared.1

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