Also known as Remington

Where: Jasper County, Indiana (40.8° N, 87.3° W: paleocoordinates 24.6° S, 34.0° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Rockford Limestone Formation, Kinderhookian (358.9 - 352.0 Ma)

• The holothurian fauna was obtained from water washings of shales which occur as partings up to a few inches thick between thin limestone layers in the upper part of the Rockford limestone unit

• group of beds-level stratigraphic resolution

Environment/lithology: offshore; poorly lithified mudstone and limestone

• "from the shale partings between the limestone beds in the section formerly quarried"

Size classes: macrofossils, microfossils

Collection methods: quarrying, sieve,

• "collected during several years of quarry operations by Mr. Chris E. Alter... this fauna... represents the total number of specimens to come from this location and be preserved"
