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)
• Stratigraphy is essentially the same as other Elmo collections except for new upper layer of non extensive limestone. The floor of the quarry where fossils taken is the "Stump layer", resting upon this floor is the white, blocky limestone from which the other collection of insects were taken. In the new quarry the blocky layer is surmounted by about two inches of soft calcareous shale, which in turn is overlain by another blocky layer of limestone. New layer can not be more than 60 feet in diameter. Above this new layer is the shaly limestone found elsewhere in the field.
• group of beds-level stratigraphic resolution
Environment/lithology: pond; lithified, lenticular limestone
Size classes: macrofossils, mesofossils
Preservation: mold/impression
