酷東西

趣味知識

Yuanyanglong is the first Early Cretaceous oviraptorosaur named from the Gobi Desert region, while other Gobi relatives come from later rocks.1

The name Yuanyanglong comes from the Mandarin word for lovebirds, because the two fossil skeletons were found together on the same block.1

The species name bainian means 'a hundred years' in Chinese, celebrating 100 years since the first oviraptorosaurs were named in 1924.1

Scientists found two partial skeletons, one with a poorly preserved skull and the other with parts of the hips, legs, and arms.1

Yuanyanglong is a basal oviraptorosaur, meaning it branched off early in the group's family tree, before many other oviraptorosaurs.1

關於 Yuanyanglong 最常被問的問題

?How big was Yuanyanglong?

It was a relatively small dinosaur, though its exact size is not given in the sources. It is described as a 'smaller' oviraptorosaur based on the two partial skeletons found.3

?What did Yuanyanglong eat?

It was an omnivore, meaning it ate both plants and small animals. Scientists found gastroliths (stomach stones) in its body cavity, which helped it grind up food.4 3

?Could Yuanyanglong run fast?

It had long legs and narrow feet, which usually help with running, but its hip bone had a very short area for leg muscles to attach. Scientists think it was probably not a fast runner and may have been better at wading in water like a modern wading bird.3

?Why was it called Yuanyanglong?

The name means 'lovebird dragon' in Chinese, because the two fossil skeletons were found lying together on the same rock block, like a pair of lovebirds.1
