Daurlong was a bird-like dinosaur that hunted fish, mammals and other dinosaurs. It lived about 120 million years ago in what is now Inner Mongolia, China. Scientists found a fossil with a blue stain in its belly, which is one of the few preserved intestines ever found in a non-bird dinosaur.1 2

Daurlong had a large blue stain in its abdomen from preserved intestines, one of only a few such finds in non-avian dinosaurs.1 2

It was a mid-sized dromaeosaurid, bigger than microraptors but smaller than some other raptors.1

Daurlong had short arms compared to many other dromaeosaurids, similar to Tianyuraptor and Zhenyuanlong.1 2

Its fossil was found in the Jehol Biota, a famous fossil site in China that preserved many feathered dinosaurs.1 2

Daurlong lived during the Aptian age of the Early Cretaceous, about 121 to 120 million years ago.4

The species name wangi honors Mr. Wang Junyou, director of the Inner Mongolia Museum of Natural History.1

Daurlong had longer and more robust teeth in its upper jaw than its relative Tianyuraptor.1

Scuverta: Daurlong was named in 2022 by Wang and colleagues based on a nearly complete skeleton found at Pigeon Hill in Inner Mongolia, China. The fossil includes preserved intestines, which is very rare.1 4
Anc discutà: Scientists are not sure if Daurlong was more closely related to microraptorines or to eudromaeosaurs, because it has a mix of features from both groups.1 2
