In 1971, a Polish-Mongolian expedition discovered at the Altan Ula IV site, in the Nemegt Basin of Ömnögovĭ province, the remains of a small theropod. The find was in 1982 reported by Halszka Osmólska and considered by her a possible specimen of Saurornithoides.[1] Later she concluded it represented a species new to science. Borogovia was by Osmólska assigned to the Troodontidae in 1987.
