The plains vizcacha (Lagostomus maximus) is a remarkable rodent of the Neotropics given several peculiar aspects of its biology, some of them quite unique among rodents or even among mammals. This book gathers specialists studying plains vizcachas from very different approaches, including palaeontology, systematics, morphology, physiology, development and conservation. It is divided in two Parts, 1) Evolutionary History, and 2) Morphology, Development and Physiology. It will surely be required reading for any researcher working with caviomorph rodents, mastozoology of the Neotropics or internal anatomy and physiology of mammals.

Luciano Luis Rasia is a PhD in Natural Sciences. He is an Assistant Researcher of CONICET (National Scientific and Technical Research Council) since 2019, working at the Vertebrate Paleontology Division of the Museo de La Plata, Argentina. He is a vertebrate palaeontologist specialising in caviomorph rodents. In his PhD dissertation, he studied the extinct chinchillids of Argentina. Now he is working mainly with extinct chinchillioids, with a focus on the evolution, palaeoecology, palaeobiogeography and biostratigraphy of the group. He has collaborated in the study of many Cenozoic faunas of Argentina. He has been teaching Compared Anatomy at the Faculty of Natural Sciences (FCNYM - UNLP) since 2011.
