Opoka and chalk were widespread facies in the epicontinental Late Cretaceous European Basin. In a commentary to Machalski and Malchyk, 2019, Zorina, 2020 postulates that ‘camouflaged’ pyroclastic material, if present in the chalk or opoka, should

Abstract Ammonoids are extinct cephalopods with external shells which predominated in many late Paleozoic and Mesozoic marine ecosystems. Stable isotope data from ammonoid shells constitute primary tools for understanding their palaeohabitats. Howeve

Opoka is a distinctive, highly fossiliferous marine spiculitic limestone typical of the Upper Cretaceous epicontinental successions of Poland, western Ukraine and some other parts of Europe. Several recent works have suggested that opoka was deposite

The fossil record of Nautilida in carbonate facies is skewed towards moulds (steinkerns) in various states of preservation, which complicates assessment of the original shell ornament of many taxa. As a remarkable exception, moulds of Epicymatoceras

The atypical Late Cretaceous nautilid Epicymatoceras vaelsense (Binkhorst van den Binkhorst, 1862) is described and illustrated on the basis of three specimens from the Maastrichtian white chalk of Denmark. One of these is probably from the lower/upp
