Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the of the Laksarska Nova Ves Formation, for which lithostratigraphic relationships are not discussed. AGE: late Karpatian (= late Burdigalian) (Hyzny and Schlogl 2011). STRATIGRAPHIC POSITION: The deposits of the abandoned clay pit are calcareous clay and clayey silt; sample was obtained from 5.5 m above base of section.

Collection methods and comments
Collection excludes:some macrofossils
Collection methods:bulk,sieve,field collection
Minimum sieve size:0.200 Maximum sieve size:1.000
Rock censused:30 kg
Reason for describing collection:taxonomic analysis
Collection method comments: COLLECTOR: Unknown. REPOSITORY: Slovakian National Museum (SNM)). METHODS: Some 30–70 kg were taken per sample, except for sample 2, which is represented by 5 kg. Each sample was wetted in a solution of hydrogen peroxide, washed through 0.2 mm, 0.5 mm, and 1 mm meshes and dried. This process was repeated several times. Finally the residue was wetted in a solution of sodium pyrophosphate and cleaned by ultrasound. This method completely removed sediment, and each sample was reduced to 0.15–0.2% of its original weight. Shark teeth were recovered at a rate higher than two specimens per kg of sediment.
Taxonomic list comments:COVERAGE: Exhaustive for chondrichthyans; teleostsbivalves, gastropods, cephalopods, scaphopods, decapods, isopods, regular and irregular echinoids, ophiuroids, siliceous sponges, and corals are also known from this section but are not listed. NOMENCLATURE: Authoritative publication, with modern nomenclature and species-resolution identifications.
