Xunmenglong was a tiny, speedy meat-eater that lived in what is now China. It was one of the smallest dinosaurs of its group, about as long as a big chicken. It probably dashed around hunting small animals in the Early Cretaceous.12

1

Xunmenglong is the smallest known member of the compsognathid group, about the size of a sub-adult Scipionyx, another small dinosaur.1

2

Its lower legs were unusually long compared to the rest of its body, which may have made it a fast runner.2

3

The fossil was originally part of a chimera, meaning it was mixed with bones from two other animals before scientists sorted it out.1

4

Xunmenglong lived about 130.7 million years ago, during the Hauterivian age of the Early Cretaceous.1

5

It is the oldest known compsognathid from Asia, found in the Huajiying Formation which may preserve the oldest Jehol Biota fauna.2

6

One unique feature is that its fourth toe bone (pedal phalanx IV-4) is longer than the third, which helps tell it apart from other compsognathids.2

Xunmenglong was named in 2020 by Xing and colleagues from a fossil that was part of a chimera. The holotype includes a pelvis, tail base, and hindlimbs, and it was found in the Huajiying Formation in China.12
Anc discutà
Scientists debate whether Xunmenglong is truly a compsognathid or a more basal member of Tetanurae, as one 2024 study suggested.1
