• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Black River/Trenton Group, Mohawkian (457.3 - 451.0 Ma)

• "In this region [i.e., the area around Poland in Herkimer Co., New York State] a few feet of Lowville are overlaid by a massive limestone, weathering lighter, of Black River aspect, which are covered by beds currently correlated with the Hull or Kirkfield, which are of more typical Trenton aspect. The massive beds evidently are the source of this specimen. Whether they are Black River or Trenton is still debatable. In some respects the fauna is clearly not that of the Chaumont, and the beds may well be younger. The writer cannot agree, however, that their correlation with the Rockland necessarily follows." (Flower, 1952 p. 56).
