“…In these two sections, Maastrichtian strata end at a major unconformity (Maastrichtian/Eocene in both cases); the highest interval may not occur in these two sections because or erosion or nondeposition. In the Bay of Biscay sections the level above which prisms no longer occur is in member III, assignable to the lower part of the A. mayaroensis Zone at Sopelana I (Lamolda and others, 1983) and Zumaya (Herm, 1965); in the DSDP cores this level is also in the lower part of the A. mayaroensis Zone. member I.…”

“…However, within the limits of the resolution of published microfossil zones (Herm, 1965;Lamolda and others, 1983;Clauser, 1987), lithologie correlations for the Bay of Biscay sections may approximate time lines. If member transitions are isochronous, the G. ganserri/A.…”

Inoceramus gradually declined in abundance over a narrow stratigraphie interval of the Maastrichtian Stage and apparently went extinct synchronously across a wide range of depths and facies near the Globotruncana ganserrilAbathomphalus mayaroensis planktonic foram zonal boundary, well before the K/T boundary. This conclusion is based largely on the observed numeric density of prismatic shell fragments of Inoceramus through eight stratigraphie sections. If care is taken to minimize the possibility of contamination through physical and biological reworking, prism density seems to follow Inoceramus density and could be a powerful new biostratigraphic tool.

“…Another step was that of establishing detailed specific zonations of these faunal sequences. Amongst these, the hemipelagic sequence in the coastal cliffs at Zumaya, on the north coast of Spain, became a classical one, by the work of Dietrich Herm (1965) of the University of Munich, for the Cretaceous, and of Axel von Hillebrandt (1965) of the same institution for the Palaeogene. An investigation of the nannoflora in this section (Fischer & Arthur, 1977) led these authors to formulate the concept of ‘disaster species’– the mass occurrence, in the basal Palaeocene, of two species – Thoracosphaera saxea and Braarudosphaera bigelowi which, whilst known from the Cretaceous, generally are rare but now appeared temporarily in rock‐forming numbers – and are now known to have done so round the world.…”

The Mediterranean region, source of so much knowledge in the world, is the site of major advances in sedimentary geology. In addition to its economic and cultural richness, the geological and geographic diversity of the region, plus its active geological processes, have long stimulated indigenous scholars, along with attracting talented outsiders such as Steno, Lyell, Walther, Kuenen and Bagnold. Since classical Hellenic times, debates about the origin of fossils and the changing positions of sea-level served as catalysts for studies of sediments, sedimentary rocks and ancient life. The presence of geologically young and easily interpreted marine shell beds in many Mediterranean coastal areas adjacent to their modern analogues was a particular stimulus for progress in sedimentary geology, for example, the very advanced stratigraphic ideas of Leonardo da Vinci, expressed solely in his unpublished notebooks. Impeding progress was the geological complexity of facies, faunas and structure in the circum-Mediterranean Alpine belts. Once the secrets of these were unlocked, however, the Mediterranean region became the source of major discoveries about syn-sedimentary tectonics, carbonate platforms, pelagic and anoxic sediments, turbidites, evaporites, aeolian processes, cyclostratigraphy, magnetic stratigraphy and impact events. In many of these Mediterranean discoveries, the critical element is the occurrence of extensive Mesozoic-Cenozoic pelagic successions whose precise age dating was made possible by pioneering biostratgraphic studies using microfossils.
