Where: Plymouth County, Massachusetts (42.1° N, 70.7° W)
• Paleocoordinates: 43.3° N, 63.6° W (Wright 2013)
• coordinate stated in text
• hand sample-level geographic resolution
When: Miocene (23.0 - 5.3 Ma)
• From 14.5-15 ft (4.4-4.6 m) below surface. Woodworth and Wigglesworth (1934, p. 21) listed the few taxa of fossils found in the greensand near Marshfield, and, on the basis of both fossils and lithology, they considered this bed probably to be the same unit as the greensand at Gay Head (Collection number 231784).
