Datai

名字的意思： “The name combines parts of the Chinese words 'tongda' (to understand) and 'antai' (stable), meaning something like 'understanding and stable'.”1

吃：植物甲龍類白堊紀晚期

Datai was an armored dinosaur that walked on four legs and had bony plates and spikes on its body. It had a pair of horns on its cheeks, which made it look extra tough. It lived in what is now China, about 90 million years ago.1 2

酷東西

趣味知識

Datai had a pair of horns on its cheeks, which is unusual and helped scientists identify it as a new species.2

The two Datai fossils were found lying on top of each other, likely because they were buried quickly by wind-blown sand.2

The neck bones of one Datai had curved holes about 2 cm wide, probably made by small creatures like mollusks burrowing in the sediment after the dinosaur died.2

Datai's tail had ossified tendons, which suggests it may have had a tail club for defense.1

Scientists used Datai's features to help make the family tree of ankylosaurs more stable, because before, many relationships were uncertain.1

Datai lived during the Late Cretaceous, about 96 to 90 million years ago, which is a time when many armored dinosaurs roamed.1

你們都在問

關於 Datai 最常被問的問題

?What did Datai eat?

Datai was a plant-eating dinosaur. It was a ground-dwelling herbivore, so it likely ate low-growing plants.3

?Did Datai have a tail club?

It likely did. Its tail bones were surrounded by ossified tendons, which suggests it may have had a tail club for defense.1

?How big was Datai?

Scientists don't know exactly, because the fossils are from young, not fully grown individuals. The known specimens were immature, so their adult size is uncertain.1

?When did Datai live?

Datai lived during the Late Cretaceous, about 96 to 90 million years ago, in what is now China.1

迷思破解王

迷思： Some people think all armored dinosaurs had tail clubs, but not all did.

真相： Datai likely had a tail club because of ossified tendons near its tail, but many other ankylosaurs did not have one.1

發現: The fossils were found in 2016 in Jiangxi Province, China, and later acquired by the Yingliang Stone Natural History Museum. In 2024, a team led by Xing Lida named the new species Datai yingliangis.1 2
仍有爭議: Scientists are still debating exactly where Datai fits in the ankylosaur family tree. Depending on the analysis, it appears either as a basal ankylosaurine or as a close relative of Pinacosaurus.1
