for the first time a Late Maestrichtian/Navarroan shark fauna (incom- 
plete as it is) from the state of North Carolina. 
LOCALITIES 
The sites from which the specimens in this report were recovered are all 
in southern Duplin County. Site 1, by far the most productive, is a borrow 
pit from which the county maintenance department extracts limestone for 
use as road fill. It is located on County Road 1148 approximately 3.2 km 
► 
due east of its junction with the north-south U.S. Highway 117, about 2.4 
km south of Rosehill. Its position is approximately 8.8 km diagonally 
northwest of the Angola Bay Game Preserve and the Northwest Branch of 
the Cape Fear River, at 34°52 , 30’' north latitude and 77°90 , 0” west 
longitude. Fossils were first discovered at this locality by Mr. John C. 
Golden, Jr., of North Charleston, South Carolina. 
At Site 1 the Peedee Formation is exposed at a depth of approximately 
4.5 to 6.1 m and consists of limestone with little traces of glauconite. The 
lack of invertebrate steinkerns and foramnifera and the surficial wear on 
the shark teeth strongly suggest that the fossils were reworked after 
original deposition elsewhere and redeposited at their present location. 
Unconformably underlying the Peedee is the Black Creek Formation, 
which has yielded no fauna at Site 1 simply because the borrow pit has 
not yet been dug deep enough. The overburden is a mixture of Castle 
Hayne limestone (Claibornian, Upper Middle Eocene), Trent Marl 
(Aquitanian, Early Miocene) and Duplin Marl (= Yorktown, Sahelian, 
Late Miocene or more likely Early Pliocene) (Berry 1947; Richards 1950; 
Cooke et al. 1943; Baum and Wheeler 1977). The shark faunas of the 
Castle Hayne, Trent, and Duplin Marls at this locality will be described 
in subsequent parts of this series. 
Site 2 is the spoil heap of an irrigation pond alongside the Rosehill 
Processing Plant (chicken Tenderers), approximately 2.4 km north of 
Rosehill on U. S. Highway 117. Several species of the Peedee fauna are 
quite common at this locality, although their condition is worn and 
abraded, indicating reworking and subsequent redeposition. The over- 
lying material at this site is also the Castle Hayne Limestone. 
Site 3, the Superior Stone Quarry, is situated 3.2 km west of U. S. 
Highway 117 at the Carroll intersection, approximately midway between 
the towns of Warsaw and Magnolia. The predominant material recovered 
from this now-defunct quarry is Castle Hayne Limestone with Late 
Eocene shark teeth and echinoids. The underlying formation is the 
Peedee, from which we obtained the same species as at Site 1. The ver- 
tebrate remains also have been worn and abraded by wave action.
