Diversity and evolutionary trends of the Family Rhinocerotidae are presented herein. The sample has a temporal range from the Middle Eocene to recent, including 41 genera and 142 species from Europe, Asia, North America, and Africa. Diversity and the first and last records have been established for each area along a temporal scale. The relative body size and weight and the gracility index of the McIII have been also analysed. The results show that the highest values in diversity and first and last records are reached in Asia. Eurasia and Africa share many taxa, while North America is more independent at generic and specific levels. Very small and very slender taxa are present in Eurasia and North America, absent in Africa. They coexist with brachypodial and generally large forms in Eurasia, whereas in North America they are replaced by large, more robust forms. From the Middle Miocene onward, middle-large …
