A similarity analysis between the large-mammal faunas of France and the Italian peninsula for the Pliocene to Middle Pleistocene highlights the taxonomic and structural renewal of large-mammal assemblages that took place at the Early-Middle Pleistocene transition. This faunal renewal coincides with a period of climatic deterioration revealed by the spread of grasslands that supported more abundant ‘cold’ taxa. Nevertheless, both in France and in Italy, this passage is not marked by a real turnover (i.e. the complete or almost complete renewal of a mammal fauna), but by an extinction phase followed by a dispersal event.

Early–Middle Pleistocene Transitions: The Land–Ocean Evidence
The Early–Middle Pleistocene transition (around 1.2 to 0.5 Ma) marks a profound shift in Earth’s climate state. Low-amplitude 41 ka climate cycles, dominating the earlier part of the Pleistocene, gave way progressively to a 100 ka rhythm of increased amplitude that characterizes our present glacial—interglacial world. This volume assesses the biotic and physical response to this transition both on land and in the oceans: indeed it examines the very nature of Quaternary climate change. Milankovitch theory, palaeoceanography using isotopes and microfossils, marine organic geochemistry, tephrochronology, the record of loess and soil deposition, terrestrial vegetationa! change, and the migration and evolution of hominins as well as other large and small mammals, are all considered. These themes combine to explore the very origins of our present biota.
