The primary species, Arginbaatar dmitrievae, was also named by Trofimov. The fossil remains date to the Aptian or Albian (Lower Cretaceous) Dzunbain Formation of Mongolia.

This genus is the only known member of its family, which is thus monotypic. Some characteristics are "Plagiaulacida"-like, while others are more akin to the further derived suborder of Cimolodonta. Exactly where it fits in is unclear. "This family shows a mixture of 'plagiaulacidan' and cimolodontan characters" (Kielan-Jaworowska & Hurum, 2001, p. 415).
