New Scotland Fm. Brachiopods, Green Pond Outlier, SE New York and NE New Jersey (Devonian of the United States)

Where: New York (42.3° N, 74.2° W)

• Paleocoordinates: 32.6° S, 46.7° W (Wright 2013)

• coordinate estimated from map

• local area-level geographic resolution

When: New Scotland Formation, Helderbergian (419.2 - 393.3 Ma)

• formation-level stratigraphic resolution

Environment/lithology: deep subtidal ramp; lithified, black, gray, calcareous mudstone and lithified lime mudstone

• Grades into Kalkberg Limestone below.

•

•2003:05:03 SEP environmental call based on given description and also Laporte (1969). In, Depositional environments in carbonate rocks--A symposium. Special Publication - Society of Economic Paleontologists and Mineralogists. Pages 98-119. Note that this may be better classified as a lime mudstone

• "light-gray-weathering dark-gray to black strongly calcareous shale. No laminations are evident...; stratification displayed only be presence of richly fossiliferous lenses and layers a few cm thick. The unit becomes fine grained and less calcareous upward."

•

•2003:05:03 changed lithology from "shale" to mudstone. This unit is really a dirty lime mudstone and may be better classified as a lime mustone. I have therefore added this a second lithology.
