Trenton Falls (Ordovician of the United States)

Also known as Trenton Gorge

Where: Oneida, Herkimer County, New York (43.3° N, 75.2° W)

• Paleocoordinates: 17.4° S, 105.1° W (Wright 2013)

• coordinate estimated from map

• small collection-level geographic resolution

When: Trenton Group, Shermanian (457.3 - 449.6 Ma)

In the section at West Canada Creek as much as 5 formations are exposed (Rathbun Mbr. of Sugar River Fm. - Upper Mbr. of Steuben Fm.). Brett & Baird (2002, Phys. Chem. Earth 27(1-3)) give the time interval that is spanned by these rocks as Shermanian.

• bed-level stratigraphic resolution

Environment/lithology: limestone

Size class: macrofossils

Reposited in the NYSM
