The nature and distribution of trace-fossil and microbenthic assemblages in Tethyan hemipelagic carbonates and marks of the Podzamcze Formation (Bajocian, Pieniny Klippen Belt) are studied. These analyses allow the identification of (1) recurring Planolites-Chondrites, Planolites-Chondrites-Zoophycos/Teichichnus and Chondrites ichno-assemblages, and (2) poor microbenthic assemblages dominated by agglutinated foraminifers and rich microbenthic assemblages dominated by diversified calcareous foraminifers as well as ostracods. A cross correlation of trace-fossil and microbenthic assemblages with the lithology and petrography of their host sediments suggests the presence of three different paleo-oxygen levels ranging from strongly dysaerobic, moderately dysaerobic to slightly dysaerobic (or aerobic)
