The isolated position of U. primae- vus is not surprising since it is a contemporary of /. vireti (Crusafont & Kurten 1976), and its phylogenetic connection with the Indarctos-Agriotherium lineage must be indirect. The fact that this lineage is divisible into two parts on the basis of cheek tooth size (and other evidence) is significant. The first is comprised of earlier, smaller and more primitive forms ( /. vireti-I. arctoides), and the second of later, larger and more advanced forms ( /. atticus-A. africanum)..
