Where: Effingham County County, Illinois (39.2° N, 88.6° W: paleocoordinates 4.5° S, 22.7° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Shumway Limestone Member (Mattoon Formation), Virgilian (303.4 - 298.9 Ma)

• Mattoon Fm. is part of the Shumway Cyclothem; all fossils collected from the lower bed of the Shumway Limestone Member

Environment/lithology: lithified, fine-grained, gray lime mudstone and argillaceous limestone

• Depositional environment was shallow, quiet water
• Lower bed: "...almost lithographic micritic limestone that when fresh is very hard....blue-grey to grey, fine grained, impure limestone that weathers reddish to buff in color"

•Upper bed: "...much more argillacoues and is very slightly bedded."

Size class: macrofossils

Reposited in the FMNH

Collection methods: quarrying,

• Mostly nautiloids reposited at FMNH, the rest are in author's private collection
