Nemegtonykus (meaning "Nemegt claw" after the Nemegt Formation where it was found) is a genus of alvarezsaurid dinosaur from the Nemegt Formation in Mongolia. The type and only species is Nemegtonykus citus. It is only the second alvarezsaur known from the Nemegt Formation, the other being Mononykus.[1]
Discovery
In 2008, the Korea-Mongolia International Dinosaur Expedition at the Altan Uul III site in the Gobi Desert excavated a dense concentration of theropod skeletons. Some of these were of Gobiraptor as well as a yet undescribed 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]

Pelvis and axial skeleton
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. The generic name combines a reference to the Nemegt with a Greek ὄνυξ, onyx, "claw", analogous to Mononykus. The scientific name means "the fast one" in Latin.[1]
