Kuru (after Kurukullā, a Tibetan Buddhist deity) is a genus of dromaeosaurid theropod from the Late Cretaceous Barun Goyot Formation of Mongolia. The genus contains a single species, Kuru kulla, known from a fragmentary skeleton including a partial skull.[1]

Discovery and naming

The holotype of Kuru kulla, IGM 100/981, was discovered by an American-Mongolian expedition at Khulsan in the Gobi Desert, Mongolia, on 5 July 1991, only hours before the discovery of Shri devi. The following year, it was reported as a distinct dromaeosaurid taxon at an SVP conference in Toronto. In their paper describing the dromaeosaurid Achillobator, Perle et al. (1999) listed a bibliographic entry titled "Morphology Dromaeosaurian dinosaur-Airakoraptor from the upper cretaceous of Mongolia".[2][3]

However, this bibliographic entry is clearly in error as no since paper existed and is definitely a reference to the SVP 1992 abstract, in which case "Airakoraptor" is a nomen nudum for IGM 100/981. Napoli et al. presumes the name "Airakoraptor" means "Kumis thief", after kumis, also known as airag or airak, a mare- or donkey-milk product made in Central Asia. In 1997 and 1999, the specimen was identified under the correct accession number in the scientific literature.[4][5]

In 2006, its surangular bone was described when Tsaagan was named.[6] Nevertheless, still in 2007 it was confused with the so-called Zos Wash specimen found in 1998, which in fact has the accession number IGM 100/3503.[7] The specimen IGM 100/981 was finally described in 2021 as the new genus and species Kuru kulla by James G. Napoli, Alexander Altieri Ruebenstahl, Bhart-Aanjan Singh Bhullar, Alan Hamilton Turner and Mark Allen Norell.[1]
