Also known as Joachim Creek

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

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Late/Upper Pleistocene (0.1 - 0.0 Ma)

• considered to be "late Pleistocene" based on faunal composition

•the fossiliferous "clay horizon showed no sequence of faunas whatsoever" and appears to be about two feet thick in an illustrated section where it is overlain by "gravel in clay" and above that "thick layers of travertine" that sealed the fissure

• bed-level stratigraphic resolution

Environment/lithology: fissure fill; claystone

Size class: macrofossils

Preservation: midden

Collected by C. Jenni, E. C. Olson, W. Read in 1939

Collection methods: quarrying,

• University of Chicago collection

•the fissure was "excavated" by Olson and Read
