==Discovery and naming== The first remains were discovered in Montana in 1980 and it was informally named as the "Hell Creek alvarezsaur" by Hutchinson and Chiappe (1998). The then unnamed species was not mentioned again until it was mentioned briefly in the 2018 Society of Vertebrate Paleontology abstract book. The species and genus were scientifically described by Denver Fowler and colleagues in 2020 based on three claw phalanges from MD-I-2, including the holotype MOR 6622, the distal end of a radius and fragmentary metatarsal.
