The Evolution of North American RhinocerosesCambridge University Press, 7.3.2005 - 218 sivua Rhinoceroses have a long and amazing history in North America. First appearing about 40 million years ago, they diversified into an incredible array of taxa, with a variety of ecologies that don't resemble any of the five living species. They ranged from delicate long-legged dog-sized forms, to huge hippo-like forms that apparently lived in rivers and lakes. This book summarizes the tremendous increase in our knowledge of North American rhinos. It includes a full systematic review, and discussions of biogeography, evolution and paleoecology, forming the most complete reference available. |
