Jablonna Reef, mollusc - crinoid biofacies (Permian of Poland)

Also known as Reef 4117

Where: Poland (52.2° N, 16.2° E: paleocoordinates 17.7° N, 25.9° E)

• coordinate estimated from map

When: Wuchiapingian (259.9 - 254.2 Ma)

Environment/lithology: reef, buildup or bioherm; limestone

• Deep to moderate (decreasing); back reef. Usually the backreef is protected against storm events and the environment shows medium or low energy, but due to small reef size the back-reef zone was subject to common storms and the lagoonal zone was non-existing in practice

Size classes: macrofossils, mesofossils
