酷東西

趣味知識

Zanabazar's skull was 272 mm long, making it the largest known troodontid skull.2

It lived during the Maastrichtian age, about 72 to 66 million years ago, right before the dinosaurs went extinct.2

Zanabazar was originally named Saurornithoides junior in 1974, but was given its own genus in 2009.2 1

Its brain was smaller than that of its relative Troodon, even though Zanabazar was bigger.1

Zanabazar had a special hole in its skull called a posttemporal fenestra, which helped lighten the head.2

It laid eggs, like all troodontids, and probably took care of its babies.2

Zanabazar 的 AI 繪圖 — 這是電腦根據科學家目前的知識，用 AI 畫出 Zanabazar 可能的樣子。這只是猜測：真正的動物可能長得不一樣，也沒有人知道牠真正的顏色。

迷思破解王

迷思： Some people think Zanabazar was a dromaeosaur like Velociraptor.

真相： Zanabazar is actually a troodontid, a different group of bird-like dinosaurs that were probably smarter and had bigger brains.2
