Robinson Locality, Brown County (Carboniferous of the United States)

Also known as Bern Limestone

Where: Brown County, Kansas (39.8° N, 95.4° W: paleocoordinates 1.3° S, 27.0° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Soldier Creek Shale Member (Bern Limestone Formation), Virgilian (303.7 - 298.9 Ma)

• Bern Limestone

• group of beds-level stratigraphic resolution

Environment/lithology: lagoonal; shale

• Although it has been suggested that shallow marine conditions existed at the site during time of deposition, it has also been argued that the cyanobacteria of the stromatolites grew in an environment of mixed fresh and marine water, either a lagoon or a bay (Foreman and Martin, 1988)
• The fossiliferous horizon is composed almost entirely of densely packed stromatolites that lie between two shales.

Size class: macrofossils
