Biostratigraphy and sedimentology of the Pelsonian (Middle Anisian) carbonate Jelovica Fm sequence have been documented in detail in the Spomen Dom section (Jelovica–Visočka Ržana region of the Stara Planina Mts, Eastern Serbia). Abundant ammonoids and foraminifers, together with rare brachiopods, nautiloids, bivalves and crinoids characterize faunal associations of the ammonoid Balatonites balatonicus Zone and the foraminiferal Pilammina densa Zone. This is the first report based on ammonoid and foraminiferal faunas, which allowed initial biostratigraphic subdivision of the Middle Anisian strata from the whole Eastern Serbia region.
