Eurypterids of the Kokomo Limestone at Kokomo (Silurian of the United States)

Where: Indiana (40.5° N, 86.1° W: paleocoordinates 29.6° S, 47.5° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Kokomo Formation, Pridoli (423.0 - 419.2 Ma)

• Kokomo Limestone (Salina D or higher)

• formation-level stratigraphic resolution

Environment/lithology: lagoonal or restricted shallow subtidal; argillaceous limestone

• "Possibly quiet water lagoonal environment, with anoxic bottom conditions as suggested by the 'poker chip' laminae, which intertongue wiht BA 3 Kirkidium Community beds of rough water type. Possibly supratidal-hypersaline."

•SEP environmental call based on given information and knowledge of regional geology

• "Limestone; finely laminated, argillaceous, especially in lower portion."

Size class: macrofossils
