Mammalia - Perissodactyla - Brontotheriidae

Taxonomy
Limnohyus robustus was named by Marsh (1872) [genotype]. It is a 3D body fossil. Its type locality is Henry's Fork Hill (Bridger C), which is in a Bridgerian terrestrial horizon in the Bridger Formation of Wyoming.

It was synonymized subjectively with Palaeosyops major by Leidy (1873); it was synonymized subjectively with Palaeosyops paludosus by Earle (1891), Hay (1902) and Lane (1932); it was recombined as Palaeosyops robustus by Osborn (1929), Gazin (1976), Mader (1998), Gunnell and Yarborough (2000) and Mader (2010).
