Where: New York (43.2° N, 78.8° W: paleocoordinates 23.5° S, 48.6° W)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Hickory Corners Member (Reynales Limestone Formation), Aeronian (440.8 - 438.5 Ma)

• member-level stratigraphic resolution

Environment/lithology: offshore ramp; lime mudstone and mudstone

• For community as a whole: shells disarticulated and sorted; normal turbulence and oxygen inferred; BA 2
