Wojkowice, Cellular Limestones unit (Triassic of Poland)

Where: Poland (50.4° N, 19.0° E: paleocoordinates 18.6° N, 24.6° E)

When: Gogolin Formation, Aegean (247.2 - 242.0 Ma)

• Cellular Limestone unit is the uppermost unit of the Lower Gogolin Beds. Two ophiuroid beds are separated by about 80 cm stratigraphic thickness.

• group of beds-level stratigraphic resolution

Environment/lithology: peritidal; lithified, dolomitic, yellow limestone and lithified, dolomitic marl

• The Cellular Limestones Unit has no evidence of marine intercalations and was presumably deposited in sabkha environment with a dominant sedimentation of lime mud. Analogical cellular structures (cells) in cellular limestone in Silesian Roetian (Zellenkalk 1) are interpreted as voids after dissolved and removed gypsum and halite crystals.

Size class: macrofossils
