Abstract

Stable isotope analysis of marine skeletal carbonates is an important tool for palaeoenvironmental reconstructions. However, in Mesozoic sedimentary sequences, diagenetic alteration often overprints the original skeletal carbonate isotope values. Yet, even if carbonate diagenesis did occur in such sequences, the original oxygen isotope values can still be preserved in enamel or bone phosphate of vertebrate fossils. Here are analysed the isotope compositions of tooth enamel structural carbonate and phosphate of various late Maastrichtian and early Palaeocene shark and ray taxa, as well as carapace bone of a late Maastrichtian marine turtle, Allopleuron hofmanni, from the type area of the Maastrichtian Stage in the southeast Netherlands and northeast Belgium. No correlation is observed between δ
