Elmo, MCZ 1925 collection (Permian of the United States)

Where: Kansas (38.6° N, 97.2° W: paleocoordinates 3.6° N, 25.8° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Wellington Formation, Artinskian (290.1 - 279.3 Ma)

• The Elmo limestone itself is a chalky, soft, almost white deposit, about five feet thick; only the very bottom, more massive layer of this stratum contains insects.

• group of beds-level stratigraphic resolution

Environment/lithology: pond; lithified limestone

• Presence of Myalinella may suggest brackish-marine conditions, but stratigraphic position and presence of conchostracans and freshwater ostracods suggest a lacustrine/pond setting.

Size classes: macrofossils, mesofossils

Preservation: mold/impression

Collected by F.M. Carpenter, P.E. Raymond in 1925; reposited in the MCZ

Collection methods: quarrying,
