3. Order Hyracoidea 



The hyraxes or conies (Fig. 471) are animals that live in Africa and 

 neighbouring regions and have persisted throughout the Tertiary as 

 small herbivorous creatures, occupying similar niches to rabbits, which 

 they resemble superficially in some ways. Fossils are known in Africa 

 back to the Oligocene and probably the group existed before that time 

 and therefore shows us something of the appearance of smaller Eocene
