Taxonomy
Dipriodon robustus was named by Marsh (1889) [genotype]. Its type specimen is YPM 11234, a tooth (right M2), and it is a 3D body fossil. Its type locality is Mammal Quarry No. 2 (UCMP V-5815), which is in a Lancian terrestrial sandstone in the Lance Formation of Wyoming.

It was recombined as Meniscoessus robustus by Osborn (1893), Hay (1902), Simpson (1929), Simpson (1936), Wood and Ormsbee (1954), Clemens (1964), Clemens and Kielan-Jaworowska (1979), Archibald (1982), Storer (1991), Lofgren (1995), Hunter (1997), Kielan-Jaworowska et al. (2004), Wilson et al. (2010) and Donohue et al. (2013).
