吃：肉肉食恐龍白堊紀晚期

Nemegtonykus was a small, speedy dinosaur that ran on long legs and used its strong claws to dig for food. It lived in what is now the Gobi Desert in Mongolia, about 72 to 66 million years ago.4 1

酷東西

趣味知識

Nemegtonykus had very short arms with one big claw on each hand, like other alvarezsaurs.1

Its name means 'swift claw' because scientists think it was a fast runner.1

Three Nemegtonykus individuals were found together with several oviraptorid skeletons in a small area less than half a square metre.1

Its leg bones were fused in a special way, which made its feet strong for running.1

Scientists think Nemegtonykus was more common in its ecosystem than previously thought, because so many fossils were found in one spot.1

關於 Nemegtonykus 最常被問的問題

?How big was Nemegtonykus?

It was a moderate-sized alvarezsaurid, but no exact length or weight is given in the sources. The holotype includes a partial skeleton without the skull, so its full size is not precisely known.3 2

?What did Nemegtonykus eat?

It was a meat-eating theropod, and like other alvarezsaurs it likely used its strong claws to dig for insects or other small prey.3 1

?Was Nemegtonykus a fast runner?

Yes, its name means Nemegt claw in Latin, and its long legs with fused foot bones suggest it was a fast runner.3 2
