Anserimimus

名字的意思： “goose mimic”1

Anserimimus was a fast, long-legged dinosaur that looked a bit like an ostrich. It had strong arms with flat claws, which made it different from its relatives. This dinosaur lived in what is now Mongolia during the Late Cretaceous period.2

酷東西

趣味知識

Anserimimus had flat, straight claws on its hands, unlike the curved claws of other ornithomimids.2

Its arms were more powerful than those of other ornithomimids, with large crests for strong muscles like the biceps.2

The hand bones (metacarpals) were fused together, making the hand stronger.2

Anserimimus lived about 70 million years ago, during the Maastrichtian stage of the Late Cretaceous.2

Only one complete skeleton of Anserimimus has been found, and it is missing the skull and lower jaws.2

Its closest relative might be Gallimimus, another ornithomimid from the same formation in Mongolia.2

Anserimimus lived alongside giant dinosaurs like Tarbosaurus and Deinocheirus in the Nemegt Formation.2

你們都在問

關於 Anserimimus 最常被問的問題

?How big was Anserimimus?

About 3 metres long and weighed around 50 kilograms, though some estimates suggest up to 170 kilograms.2

?What did Anserimimus eat?

Scientists think it was probably an omnivore, but since its skull is missing, its exact diet is unknown.2

?When did Anserimimus live?

It lived about 70 million years ago, during the Late Cretaceous Period.2

?Why did Anserimimus have flat claws?

Nobody knows for sure. The flat, straight claws may have been used for a different way of gathering food, but the animal's skull is missing so its diet is hard to study.2

給恐龍專家

學名: Anserimimus
命名者: Barsbold 19884
類群: 似鳥龍類
科 / 演化支: Ornithomimidae4
分類: Theropoda > Ornithomimosauria4
岩石的年代: 72 到 66 百萬年 (Maastrichtian)4
岩層: Nemegt4
國家: 蒙古4
化石紀錄: The Paleobiology Database 收錄 2 筆4
發現: Anserimimus was named by Mongolian paleontologist Rinchen Barsbold in 1988, based on a skeleton found during a Soviet-Mongolian expedition to the Gobi Desert in the late 1970s.2
仍有爭議: Scientists are not sure what Anserimimus ate, because its skull has never been found. Its strong arms and flat claws might mean it had a different diet or way of gathering food than other ornithomimids.2
