Where: Malopolskie, Poland (50.1° N, 19.6° E: paleocoordinates 3.4° S, 20.8° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Gnathodus girtyi collinsoni conodont zone, Orlej Limestone Formation, Brigantian (336.0 - 326.4 Ma)
• Gromczakiewicz-Lomnicka: "The area of Orlej was transitional between the zone of the Carboniferous Limestone and the zone of Culm"; "150 m of Carboniferous beds"
•Olempka: “The age of these beds was determined on brachiopod evidence as Late Visean by Czarniecki (1955, 1956). Conodonts from the limestone intercalations indicate the Gnathodus girtyi collinsoni Zone, which corresponds in age to the Visean/Namurian boundary (Belka 1982).”
•Probably P2 (late Brigantian) given Olempska's description
• group of beds-level stratigraphic resolution
Environment/lithology: shallow subtidal; pyritic, black, muddy shale and dolomitic limestone
•From Olempska 1993: "The Orlej section represents a relatively thick, over 100 m in thickness, sequence of dark grey and black clay and sandy shales with only two intercalations of limestone beds. It is exposed out in the Orlej Quarry in the vicinity of Zalas, in the southern Cracow Upland (Fig. 1). This is the only argillaceous sequence of the Visean, with a paleontologically documented age, on the eastern fringe of the Upper Silesian Coal Basin (Belka 1982)."
Size classes: macrofossils, mesofossils
Preservation: mold/impression, permineralized, replaced with pyrite
Collected by Stanislaw Czarniecki in 1954, 1955
• Specimens at Institute of Paleobiology of the Polish Academy of Sciences, Warsaw (ZPAL).
