Available in PDF, EPUB and Kindle. Book excerpt: "Eighteen rodent species are recognized from the Fitterer Ranch fauna of North Dakota on the basis of more than a thousand collected specimens. Of the species recognized, four are new: the prosciurine aplodontiids Prosciurus hogansoni and Altasciurus leonardi, the heliscomyid Heliscomys borealis, and the cricetid Eumys lammersi. A previously described castorid from this fauna, Oligotheriomys primus Korth, 1998, is considered a synonym of "Eutypomys" magnus Wood, 1937, on the basis of the recovery of lower dentitions but is retained in the genus Oligotheriomys. A single specimen is questionably referred to Microparamys, a genus elsewhere limited to the Eocene (Clarkforkian-Chadronian land mammal ages). The rodent fauna appears to be a combination of predominantly Orellan and Whitneyan species (early Oligocene), suggesting that the section might transcend the Orellan-Whitneyan boundary. However, the rodent fauna does not alter significantly from the lowest to the highest horizons."--Provided by publisher.

This book was released on 2013-11-21 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nearly half of the known species of mammals alive today (more than 1600) are rodents or "gnawing mammals" (Nowak and Paradiso, 1983). The diversity of rodents is greater than that of any other order of mammals. Thus, it is not surprising that the fossil record of this order is extensive and fossil material of rodents from the Tertiary is known from all continents except Antarctica and Australia. The purpose of this book is to compile the published knowledge on fossil rodents from North America and present it in a way that is accessible to paleontologists and mammalogists interested in evolutionary studies of ro dents. The literature on fossil rodents is widely scattered between journals on paleontology and mammalogy and in-house publications of museums and universities. Currently, there is no single source that offers ready access to the literature on a specific family of rodents and its fossil history. This work is presented as a reference text that can be useful to specialists in rodents (fossil or recent) as weIl as mammalian paleontologists working on whole faunas. Because the diversity of rodents in the world is essentially limitless, any monograph that included all fossil rodents would similarly be limitless. Hence, this book is limited to the re cord of Tertiary rodents of North America. The several species of South American (caviomorph) rodents that invaded North America near the end of the Tertiary are also not included in this text.
