Paperback. Condizione: New. Print on Demand. This book's subject is the examination of vertebrate microfaunas recovered by the Yale Peabody Museum's six-season paleontological project in Fayum Province, Egypt. Before the project, only a few specimens of smaller mammals were found in Fayum Province, and scientists previously assumed smaller mammals weren't preserved there. However, the Yale Peabody Museum team recovered abundant vertebrate fossils of microfaunal size by using a combination of screening unconsolidated sands, quarrying clay-rich channel sands, and collecting wind-eroding unconsolidated sands. Their excavations greatly enlarged the known Fayum Oligocene microvertebrate faunas. The volume describes the specimens, discusses their significance in the broader context of mammalian evolution, and presents new understandings of the environment and history of the North African Middle Tertiary, as well as the possible relationships between the Oligocene forms and modern genera. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.
