In the frontal part of the Bílé Karpaty Unit the Upper Cretaceous sediments of the Antonínek Formation were observed in excavation for pond near Kozojídky village. The strata consist of medium to thick rhythmic turbidites composed of poorly sorted silty sandstones, siltstones and calcareous clays, intercalated with rare turbidite layers of limestone mudstones. Foraminifer plankton evidenced the Maastrichtian age of strata. The new find indicates the tectonic slice of the Antonínek Formation not detected during previous geological survey
