The outcrop of the Bataszek brickyard in southeastern Transdanubia of Hungary exposes clayey silt in a 20 to 30 m thickness, containing several thin, sandy, often limonitic, poorly sorted coquina layers. We interpret the silt as sublittoral deposit of the Late Miocene Lake Pannon. The sandy intercalations are probably storm deposits or sediment gravity flows from a nearby littoral environment. The mollusk fauna of the silt is largely autochthonous, and dominated by Congeria rhomboidea and Lymnocardium hungaricum. The partly reworked faunas of the sandy intercalations have a different composition. The entire fauna is very similar to the classic faunas of Okrugljak and Szekszard, and to the fauna of Jazovnik (faciostratotype of the Portaferrian Substage). All of these deposits belong to the Congeria rhomboidea Zone. Other fossils from the outcrop include ostracods, fishes, algae, spores, and pollen. The dinoflagellates indicate that the Bataszek deposits are in a slightly higher stratigraphic position than the top of the Spiniferites validus Zone.
