PBDB Collection

Elmo, YPM 1921 collection (Permian of the United States)

Also known as Insect Hill

Where: Kansas (38.6° N, 97.2° W: paleocoordinates 3.7° 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 about five feet thick; only the very bottom, more massive layer of this stratum contains insects. Overlies underlying terrestrial (swamp) shale with a sharp and irregular contact.

• group of beds-level stratigraphic resolution

Environment/lithology: pond; lithified, gray, argillaceous limestone

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

• Soft, argillaceous limestone of very light grey color and almost chalky texture, disposed in layers 0.5 to 4 inches thick.

Size classes: macrofossils, mesofossils

Preservation: mold/impression
