Fossiliferous Pebbles in "Pensauken Gravel" at Princeton, New Jersey

Abstract

Identification of fossils preserved in chert pebbles in the "Pensauken gravel" at Princeton, New Jersey, demonstrates that these pebbles came from Paleozoic rocks of northwestern New Jersey and adjacent parts of New York. They were presumably transported to Princeton by the Delaware River when it flowed, as postulated by Campbell and Bascom, across northwestern New Jersey on its way to Trenton. The fossils do not, however, support Campbell and Bascom's assumption that the Hudson River once joined the Delaware River somewhere in central New Jersey.
