Trench Z.orb-8, Debnik Anticline, Cracow Region (Devonian of Poland)

Where: Poland (50.2° N, 19.7° E: paleocoordinates 16.9° S, 27.7° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Early/Lower Famennian (376.1 - 370.6 Ma)

• Standard Conodont Zone: may be upper Palmatolepis crepida zone; Local Brachiopod Zones & Intervals (this paper): Dmitria gibbosa interval; lowest part of Grained and Micritic Limestone unit

• group of beds-level stratigraphic resolution

Environment/lithology: open shallow subtidal; lithified, shelly/skeletal, gray wackestone

• represents a relatively deep-water, palmatolepid-polygnathid biofacies; marks more favorable environmental conditions
• gray, medium-bedded bio-micrites with crinoids, echinoids, ostracods, scolecodonts, bryozoans, algae and conodonts.

Size classes: macrofossils, mesofossils

Collection methods: bulk,
