ammonites
Roztocze Hills, serpulid-microbialite reefs, Lublin Upland (Miocene of Poland)

Also known as Reef 676

Where: Poland (50.8° N, 22.2° E: paleocoordinates 51.1° N, 21.0° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Serravallian (13.7 - 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
