Grabina section, Set A (Devonian of Poland)

Also known as Kowalotrochus sanctacrucensis association

Where: Wojewodztwo Swietokrzyskie, Poland (50.8° N, 20.7° E: paleocoordinates 20.4° S, 33.6° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Upper Sitkówka Beds Member (Kowala Formation), Middle Frasnian (382.4 - 379.5 Ma)

• STRATIGRAPHIC RELATIONS: THICKNESS: From upper Sitkowka beds of the Kowala Formation, slightly higher in regional section than the Kadzielnia Mbr. AGE: Middle Frasnian according to Fig. 2 of Krawczynski (2002). STRATIGRAPHIC POSITION: From near top of set A, lower part of Grabina section.

• group of beds-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; lithified, shelly/skeletal reef rocks

• ENVIRONMENT: Reef gastropod association, in otherwise bank to reef facies, adjoining detrital and coral-rich buildups. TECTONIC SETTING: No tectonic data reported. SEQUENCE STRATIGRAPHY: From base of F-1 T-R cycle of Racki (1997), presumed from interpretation to be the transgressive portion.
• GENERAL LITHOLOGY: Biolithites and organodetrital limestones. Detailed lithological data reported by Racki (1993). LITHIFICATION: lithified, based on observatio of figured specimens.

Size class: macrofossils

Preservation: cast, mold/impression
