Nemegtonykus (meaning "Nemegt claw" after the
alvarezsaurid dinosaur from the Nemegt Formation in Mongolia. The type and only species is Nemegtonykus citus. It is 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
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. The generic name combines a reference to the Nemegt with a Greek ὄνυξ, onyx, "claw", analogous to Mononykus. The specific name means "the fast one" in Latin.[1]
The
pubic bone, parts of other pelvic bones, the left hindlimb and the right shinbone. The left hindlimb and the tail were articulated. The other bones were associated on a small surface.[1]
