R1183C (Cretaceous of the United States)

Where: Sayreville County, New Jersey (40.5° N, 74.3° W: paleocoordinates 34.0° N, 38.5° W)

• coordinate estimated from map

• hand sample-level geographic resolution

When: Complexiopollis-Atlantopollis pollen zone, Woodbridge Clay Member (Raritan Formation), Cenomanian (100.5 - 93.9 Ma)

• The pollen zone is dated as middle to possibly late Cenomanian in age.

Environment/lithology: fluvial; argillaceous, silty sandstone

• The Raritan Formation is presently considered to represent subaerial deltaic plain and/or fluvial environments of deposition. The lithology of the member is characteristic of overbank deposits of natural levees and unimpeded floodplains.
• Chiefly interstratified light-colored sands and dark clays and silts which vary in thickness, composition, and texture over short distances.

•The upper part of the Woodbridge Clay Member consists of horizontally stratified interbedded sequences of thin, dark silts and light sands.

Size class: microfossils

Preservation: original sporopollenin

Reposited in the USGS

Collection methods: bulk, chemical, hydrochloric, hydroflouric

• Samples were prepared for palynological examination by standard chemical maceration techniques, followed by heavy liquid separation in zinc bromide. Sample residues were mounted in glycerine jelly on slides, and the slides are stored in the palynology laboratory, U.S. Geological Survey, Reston Virginia.
