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 10.5 m above base of section. |

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. | |||
