Inversand Company marl pit, Sewell (MFL) (Cretaceous to of the United States)

Also known as KT loc. 428

Where: Gloucester County, New Jersey (39.8° N, 75.2° W: paleocoordinates 40.2° N, 51.8° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Hornerstown Formation (Rancocas Group), Late/Upper Maastrichtian to Late/Upper Maastrichtian (70.6 - 61.7 Ma)

• Mixed Maastrichtian-Danian assemblage from the main fossiliferous layer (most likely a Maastrichtian lag deposit)

•"articulated skeletons and other unworn material, including most of the birds, are more probably not reworked but part of a new phase of deposition in the earliest Paleocene (D. Parris, pers. comm.)" (Hope 2002).

•Described as the "main fossiliferous layer"

• bed-level stratigraphic resolution

Environment/lithology: shallow subtidal; poorly lithified, glauconitic sandstone

Size classes: macrofossils, mesofossils

Collection methods: salvage, quarrying,
