Prolibytherium magnieri : Female

by Miniature Museum

Prolibytherium would have superficially resembled an okapi or a deer. Unlike these, however, Prolibytherium displayed dramatic sexual dimorphism, in that the male had a set of large, leaf-shaped ossicones with a width of 35 centimetres , while the female had a set of slender, horn-like ossicones.
