Where: Poland (50.8° N, 20.7° E: paleocoordinates 18.7° S, 31.4° E)
• coordinate based on political unit
• outcrop-level geographic resolution
When: Late/Upper Frasnian (379.5 - 376.1 Ma)
• 47 samples collected from thickness of about 8.5 meters surrounding Frasnian-Famennian boundary, which is placed at base of bed 8. This collection is number PG 16 from within bed 4. [JA: the lower part of the section is said to be entirely late Frasnian]
• bed-level stratigraphic resolution
Environment/lithology: marine; peloidal, shelly/skeletal grainstone
• Overall sequence interpreted as open marine photic zone, fore shoal (beds 1 to 4; microfacies 1 to 3) to mixed algal backshore and crinoidal foreshore (beds 5 through 11; microfacies 4). Several microfacies are also recognized: 1. burrowed bioclastic wackestones and packstones. 2. burrowed bioclastic peloidal packstones (2a. fine-gr. packstones, heavily bioturbated; 2b. coarser packstones with larger bioclasts). 3. peloidal laminated bioclastic grainstones (3a. fine grainstones with same bioclasts as microfacies 2; 3b. coarser, with cross-stratification and alternation of fine and coarse bioclastic laminae); 4. coarse grained floatstones and grainstones (4a. microconglomeratic floatstones with corals; 4b. coarse grainstone-rudstone with a few oncoids and rare micritized ooids; 4c. med.. to coarse crinoidal grainstone rich in subrounded microbreccias). This collection is 3a.
