Where: Ohio (39.0° N, 84.0° W)

• Paleocoordinates: 25.5° S, 112.0° W (Wright 2013)

• basin-level geographic resolution

When: Liberty Formation, Richmondian to Richmondian (449.6 - 443.7 Ma)

• formation-level stratigraphic resolution

Environment/lithology: deep subtidal ramp; lithified, shelly/skeletal packstone and mudstone

• "BA3 (S. Holland, pers. comm.) Additional Geographic, Stratigraphic, and Geologic Information added by S.M. Holland, 23 September 1999, as well as the complete species-level lists of Dalve, 1948.
• interbedded limestone and mudstone, in roughly equal proportions. mudstone thin bedded and poorly fossiliferous. limestone consists of thin to medium bedded skeltal packstones and grainstones, and calcisiltite. skeletal grainstones commonly cross-bedded and megarippled. calcisiltites commonly with planar lamination, hummocky cross-lamination, tool marks, and trace fossils.

Size class: macrofossils

Preservation: original calcite, replaced with phosphate
