E-Bar-3.5 - Keeler's Eskimo Bar ice cream stand (Cambrian of the United States)

Where: Columbia County, New York (42.2° N, 73.7° W: paleocoordinates 34.1° S, 88.3° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Elliptocephala asaphoides trilobite zone, Browns Pond Formation, Dyeran (516.0 - 513.0 Ma)

• LITHOSTRATIGRAPHY: Initially entered as "Middle Granville Fm". From Anse Maranda Fm, which overlies the Lauzon Fm. Equivalent to the upper Browns Pond, Middle Granville, and lower Hatch Hill Fm of New York. AGE: Stage designation not stated in publication, initailly entered as "Dyeran"; from middle Olenellus zone. STRATIGRAPHIC POSITION: From near base of section, at 4.0 m.

• bed-level stratigraphic resolution

Environment/lithology: slope; lithified, dolomitic, gray siltstone

• ENVIRONMENT: The limestone-bearing part of the E-Bar locality represents one of the most proximal, dark siltstone facies in the Lower Cambrian slope facies of the Taconic allochthon.
• LITHOLOGY: Dark grey debris flow, siltstone granule- to pebble-dominated with dolomitic matrix, with pebbles to boulders of echinoderm-intraclast granule pack- to grainstone (large ellipse) and calcareous siltstone (small ellipse). LITHIFICATION: Lithified, on the basis of figured specimens, facies descriptions, and sample preparation.

Size class: macrofossils

Preservation: cast, replaced with phosphate

Collected by Landing & Bartwoski; reposited in the NYSM

Collection methods: bulk, acetic

• COLLECTORS: Not stated in text, but presumably E. Landing and K. Bartowski. REPOSITORY: New York State Museum.
