AB The petrographic analysis of the inoceramid shells allows to identify some microstructures, which suggesttheir early modification, previously and during the first burial stages. In this sense, it is important to emphasizethe borings produced by epibionts and the formation of an early ferrous-manganese coating in the outersurface of the shell. The desegregation of the prismatic framework and its dispersion in the sediment areother processes that took place during the early stages of burial. The study of the post-mortem modificationof the shells brings forward some evidences about the marine bottom oxygenation in the Basque-CantabrianBasin, just before the inoceramid extinction near the lower-upper Maastrichtian boundary (~69,3 m.a.)
