Mazon Creek, USNM Lacoe Collection (Carboniferous of the United States)

Also known as ETE Locality 802

Where: Illinois (41.3° N, 88.4° W: paleocoordinates 4.6° S, 23.4° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Francis Creek Shale Member (Carbondale Formation), Westphalian D (311.4 - 306.9 Ma)

Environment/lithology: interdistributary bay; lithified, concretionary, sideritic mudstone

• Illinois basin

Size class: macrofossils

Preservation: mold/impression

Collected by R.D. Lacoe, Mr. Daniels in 1865-1892; reposited in the USNM

• Mr. Lacoe of Pittston, Pennsylvania, paid local collectors, including Mr. Daniels, to collect specimens from Mazon Creek area. In the plant-bearing- beds of the anthracite and bituminous regions Mr. Lacoe occasionally secured a single insect wing, and when the finds became sufficient to warrant digging for them he would specially detail a collector to examine the shales of a given locality.
