Daurlong (meaning "

In 2022, Daurlong wangi was described as a new genus and species of dromaeosaurid theropod dinosaurs by Xuri Wang, Andrea Cau, Bin Guo, Feimin Ma, Gele Qing, and Yichuan Liu based on these remains. The generic name, "Daurlong", combines a reference to the Daur Nation with the Chinese "龙" ("lóng"), meaning "dragon." The specific name, "wangi", honors Wang Junyou, the director of the Inner Mongolia Museum of Natural History.^[1]

Description

Daurlong was a mid-sized dromaeosaurid, about 1.5 m (4.9 ft) long. The preserved specimen is 85% the size of the Tianyuraptor holotype, and 93% the size of the Zhenyuanlong holotype. The skull is about 94% the length of the femur, and the forelimbs are less than 60% of the length of the hindlimbs. The specimen preserves plumage along the back of the skull and neck, and the edges of the tail. The fossil does not include pennaceous remiges and rectrices, as in Zhenyuanlong. A bluish layer preserved in the Daurlong specimen ribcage matches the intestinal tract seen in the Scipionyx holotype.^[1]

Classification

In their phylogenetic analyses, Wang et al. (2022) recovered Daurlong as a member of the Dromaeosauridae, in a clade containing Tianyuraptor and Zhenyuanlong. The cladogram below displays the results of their phylogenetic analyses.^[1]
