Abdarainurus barsboldi
(Barsbold's Abdarain Nuru Tail)Etymology
Abdarainurus is derived from "Abdarain Nuru" (the Russian spelling for the Abdrant Nuru locality where it was found) and the Latin "urus" (tail).

barsboldi, honours Mongolian palaeontologist Rinchen Barsbold.

Discovery
The remains of
Abdarainurus were discovered in the Alagteeg Formation at Abdrant Nuru, northern Gobi Desert, Ulan Nuur Depression, Mongolia, by A. V. Sochava in 1970 during the Joint Soviet-Mongolian Paleontological expedition which ran from 1967 to 1990. V. P. Tverdokhlebov of Saratov State University excavated the remains later the same year.
The
holotype (PIN 5669/1) consists of nine tail vertebrae (A1-A8, A10) with chevrons attached to A3 and A4, plus another chevron which is missing its corresponding vertebra. The fossils lay ignored with not so much as a passing mention in the literature, until they landed on the workbench of Andrey Podlesnov; a preperator and researcher at the Borissiak Paleontological Institute of the Russian Academy of Sciences.
