Horog-hegy section (Triassic of Hungary)

Where: Veszprem, Hungary (46.9° N, 17.6° E: paleocoordinates 1.4° N, 29.1° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Felsörs Formation, Anisian (247.2 - 242.0 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: basinal (); limestone

• Mainly composed of limestone deposited in deeper sublitoral, basinal environments

Size class: macrofossils

Collection methods: Most of the bivalve remains are internal molds with remians of shell. Internal features could be studied only in a very few cases. The unfavorable state of preservation allowed usually tentative identifications. The material has been kept at the Department of Geology and Palaeontology of the Hungarian Natural History Museum (HNHM)
