A. calvoi Bonaparte, 1991 (type)
It was named by paleontologist Jose Bonaparte in 1991. It walked on two legs, had a long tail, and its leg structure suggests that it was a fast runner. It may have eaten insects. It was more basal than other, better-known, members of its family, such as Mononykus and Shuvuuia.
