    Beschreibung / Inhaltsverzeichnis: The first textbook devoted to the late Cenozoic (Neogene) mammalian biostratigraphy and geochronology of Asia, this volume deploys cutting edge biostratigraphical and geochemical dating methods to map the emergence of mammals across the continent. Written by specialists working in a variety of Asian regions, it uses data from many basins with spectacular fossil records to establish a groundbreaking geochronologic framework for land mammal evolution. Asia's violent tectonic history has resulted in some of the world's most varied topography, and its high mountain ranges and intense monsoon climates have spawned widely diverse environments over time. These geologic conditions profoundly influenced the evolution of Asian mammals and their migration into Europe, Africa, and North America. Focusing on amazing new fossil finds that have redefined Asia's role in mammal evolution, this textbook synthesizes information from a range of field studies on Asian mammals and biostratigraphy, helping to trace the histories and movements of extinct and extant mammals from various major groups and all northern continents, and providing geologists from all disciplines with a richer understanding of a variety of Asia's terrains.

    Beschreibung: Cases of convergent evolution, particularly within ecomorphological contexts, are instructive in identifying universally adaptive morphological features across clades. Tracing of evolutionary pathways by which ecomorphological convergence takes place can further reveal mechanisms of adaptation, which may be strongly influenced by phylogeny. Ecomorphologies of carnivorous mammals represent some of the most outstanding cases of convergent evolution in the Cenozoic radiation of mammals. This study examined patterns of cranial shape change in the dog (Canidae) and hyena (Hyaenidae) families, in order to compare the evolutionary pathways that led to the independent specialization of bone-cracking hypercarnivores within each clade. Geometric morphometrics analyses of cranial shape in fossil hyaenids and borophagine canids provided evidence for deep-time convergence in morphological pathways toward the independent evolution of derived bone-crackers. Both clades contained stem members with plesiomorphic generalist/omnivore cranial shapes, which evolved into doglike species along parallel pathways of shape change. The evolution of specialized bone-crackers from these doglike forms, however, continued under the constraint of a full cheek dentition and restriction on rostrum length reduction in canids, but not hyaenids. Functionally, phylogenetic constraint may have limited borophagine canids to crack bones principally with their carnassial instead of the third premolar as in hyaenids, but other cranial shape changes associated with durophagy nevertheless evolved in parallel in the two lineages. Size allometry was not a major factor in cranial shape evolution in either lineage, supporting the interpretation of functional demands as drivers for the observed convergence. The comparison between borophagines and hyaenids showed that differential effects of alternative functional "solutions" that arise during morphological evolution may be multiplied with processes of the "macroevolutionary ratchet" already in place to further limit the evolutionary pathways available to specialized lineages.
