Where: Scotland, United Kingdom (55.0° N, 2.0° W: paleocoordinates 11.1° S, 0.9° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Cementstone Group, Tournaisian (358.9 - 346.7 Ma)

• It is therefore of interest to be able to record a Scottish example of C. devonicus from ash beds in the transition zone at the base of the Cementstone Group and overlying typical Upper Old Red Sandstone.

Environment/lithology: gray ash

• beds of grey to purplish ash

Size class: mesofossils
