oviraptorid but three were of Alvarezsauridae. One specimen, MPC-D 100/206, was considered cf. Mononykus sp. but the other two represented a species new to science.[1]

In 2019, the type species Nemegtonykus citus was named and described by Lee Sungjin, Park Jin-Young, Lee Yuong-Nam, Kim Su-Hwan, Lü Junchang, Rinchen Barsbold and Khishigjav Tsogtbaatar.
