Two samples of concretions from Maastrichtian and Paleocene grey clays/claystones of the Subsilesian Unit near Frýdek-Místek two samples of concretions were studied. The sample from the Paleocene/Eocene clays of the Frýdek Formation is phosphate nodule composed of highly prevailing amount of fluorapatite, low content of quartz and small amount of chlorite, muscovite and accessories. The phosphate nodules may be in fact coprolites. The sample from the Maastrichtian Frýdek Formation is sedimentary siderite (pelosiderite) with trace content of calcite.
