Cramaucheniinae is a paraphyletic subfamily of
middle Eocene (Mustersan SALMA). The size range of the group ranged from small, basal forms to larger and more derived forms. During their evolution, the cramaucheniines undergone a trend from evolving from small basal forms such as Polymorphis into larger, more derived taxa such as Theosodon.[1][2]
