near the village Kalinove, Avilovka Suite (Carboniferous of Ukraine)
Where: Ukraine (48.5° N, 38.5° E: paleocoordinates 9.9° N, 36.3° E)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Gzhelian (303.7 - 298.9 Ma)
• Uppermost Moscovian;
•Lomovatkian Regional Stage
Environment/lithology: reef, buildup or bioherm; limestone
• Outcrop a bioherm has a lenticular shape with a maximum thickness of 5.2 m that decreases along the strike to 0.7-1.0 m. this buildup is an algal-sponge bioherm. It is composed primarily of phylloid algae (Pl. 3H). Primitive forms of Tubiphytes and perhaps cyanobacteria were identified. Some parts of the bioherm also consist of aggregates of spicules of siliceous sponges. Spicules are in some cases scattered in the dark mass of primitive Tubiphytes, probably trapped in the growth process. Often there are also bryozoans, and foraminifera. Sponge spicules dominant limestone is similar to those described from the Late Viséan of NE Morocco
• limestones N2 and N3; algal-sponge bioherm
Size classes: macrofossils, mesofossils
