Where: Jefferson County, Missouri (38.3° N, 90.4° W: paleocoordinates 25.6° S, 37.7° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Glen Park Formation, Kinderhookian (358.9 - 352.0 Ma)

• This formation was previously known as the Horton Creek member of the Hannibal Formation. Due to the existence of a paraconformity between the Devonian-Mississippian contact, the exact stratigraphic position of these beds has been corrected several times since their first description in the early 1900's. Carter contains a complete description of the history of work done on these sections.

•

•Given as 397 - Glen Park section.

•

•This is sometimes given as the Glen Park Limestone member of the Sulphur Springs Formation (e.g., Yochelson & Saunders 1967 p. 46).

• group of beds-level stratigraphic resolution

Environment/lithology: shallow subtidal; lithified, sandy limestone

Size classes: macrofossils, mesofossils

Collection methods: This collection is from the Field Museum of Natural History and the Carnegie Museum of Natural History.
