FIGURE 1 in Pteropoda (Mollusca, Gastropoda, Thecosomata) from the Paleocene-Eocene Thermal Maximum (United States Atlantic Coastal Plain)
FIGURE 1. Map of the northeastern coast of the USA, showing part of the northern portion of the Atlantic Coastal Plain and the location of the studied cores: BR = Bass River; C = Clayton; WL = Wilson Lake; CD = Cambridge-Dorchester; MCBR = Mattawoman Creek-Billingsley Road. The New Jersey Coastal Plain is the northern section of the Salisbury Embayment. In outcrop, the Fall Line marks the change from Precambrian and Paleozoic rocks of the Piedmont province in the west to the relatively undeformed, slightly dipping Mesozoic and Cenozoic sediments of the Coastal Plain in the east (Gibson and Bybell, 1994). For visual ease, the New Jersey Coastal Plain and the Salisbury Embayment labels are delineated offshore.
