Sternberger Kuchen, lecker. Hier werden einführend und anschaulich Geologie und Fossilien vorgestellt.
The study of biodiversity through geological time provides important information for the understanding of diversity patterns at the present day. Hitherto, much effort has been paid to studying the mass extinctions of the Phanerozoic but the research emphasis has now changed to focus on what occurred between these spectacular catastrophic events. After the Cambrian 'explosion' of marine organisms with readily preservable skeletons, there have been two intervals when life radiated dramatically - the Ordovician Period, and the mid-Mesozoic-Cenozoic eras. These intervals saw a fundamental reoganization of biodiversity on a hierarchy of biogeographical scales. The size of these diversity increases and their probable causes are topics of intense debate, and there is an intriguing link between the dispersal of continents, changing climates and the proliferation of life.Palaeobiogeography and Biodiversity Change: the Ordovician and Mesozoic-Cenozoic Radiations illustrates many aspects of the two great episodes of biotic radiation and shows how long periods of time and plate tectonic movements have a fundamental influence on the generation and maintenance of major extant biodiversity patterns.
