Cerova-Lieskove section (sample 21) [Laksarska Nova Ves Fm] (Miocene of Slovakia)

Where: Slovakia (48.6° N, 17.4° E: paleocoordinates 47.7° N, 16.9° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Laksarska Nova Ves Formation, Burdigalian (20.4 - 16.0 Ma)

• 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.

• bed-level stratigraphic resolution

Environment/lithology: offshore; poorly lithified, calcareous claystone

• ENVIRONMENT: Not stated in text.
• SPECIFIC LITHOLOGY: Calcareous clay and clayey silt. LITHIFICATION: Poorly lithified.

Size classes: macrofossils, mesofossils

Collection methods: bulk, sieve,

• 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.
