"Clisospira" reinwaldti type section (Ordovician of Estonia)

Where: Estonia (59.4° N, 24.8° E: paleocoordinates 35.1° S, 2.2° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Pygodus anserinus conodont zone, Pärtliorg Member (Kõrgekallas Formation), Uhaku (459.7 - 458.0 Ma)

• "late Middle Ordovician Pärtlioru Member of the Kõrgekallas Formation (Darriwilian; Uhaku regional stage)." "Except for its lowermost part, the formation falls within the P. [Pygodus] anserinus conodont Zone and the Conochitina tuberculata chitinozoan Biozone (Hints, 1997; Nõlvak et al., 2006; Viira, 2008)."

• group of beds-level stratigraphic resolution

Environment/lithology: shallow subtidal; lithified, argillaceous limestone

• shelf carbonates
• "The Kõrgekallas Formation is a thin-bedded argillaceous limestone unit in the upper part of the Uhaku Stage. It is only ∼ 2 m thick in the northwestern outcrop area and ∼ 18 m thick in the northeastern part (Hints, 1997). Within the Baltic Oil Shale Basin, the upper beds (Pärtlioru Member) contain the oldest kukersite in Estonia."

Size class: macrofossils

Preservation: mold/impression
