Medobory region (Ternopil-Kamyanets-Podilskyy), serpulid-microbialite buildups (Miocene of Ukraine)

Also known as Reef 825

Where: Ukraine (49.0° N, 26.4° E: paleocoordinates 49.4° N, 25.3° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Serravallian (13.8 - 11.6 Ma)

• Lower Sarmatian

• group of beds-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; lithified reef rocks

• brackish environment
• The buildups are composed mainly of calcite precipitates. Skeletal organisms represented by serpulid tubes and bryozoans are of minor importance and comprise merely a few percent of the rock volume. They are overgrown with micritic peloidal microbialites that are the major reef component.

Size classes: macrofossils, mesofossils
