for those who seek them, although hitherto the seekers have been few and 
long between. We hope our contribution will stimulate further delving 
into this fallow field.

LOCALITIES 
Figure 1 shows the sites from which dinosaurian (or supposedly 
dinosaurian) bones have been recovered. 
(1) Marl pits of James King, Sampson County. According to Kerr 
(1875: 198-199) King’s farm lay “some 10 miles from the depot [Faison’s 
Depot], southwest .... This locality is on the waters of Six Runs Creek.” 
The heterogeneous collection of bones upon which Cope based Hypsibema 
crassicauda was found in the “blue marl,” now the Black Creek Formation. 
(2) ,Marl pit of W. J. Thompson, Sampson County, “about ten miles 
distant from the marl pit in which the Hypsibema was found” (Cope 
1875: 40). This appears to be the locality mentioned in passing by Kerr 
(1875: 198) : “ [Blue marl sample] No. 35 is from the farm of J. C. Pass, a 
mile and a half west of Faison’s Depot .... Another well known outcrop 
in the same neighborhood is at Dr. Thompson’s. ...” 
Stephenson’s (1923) map shows an extensive area of Duplin Marl 
(Miocene or Pliocene) extending southward from Faison. In the same 
region Stuckey’s (1958) map indicates only an insignificant, mile-wide 
patch of Duplin (Yorktown) lying west of Six Runs Creek. The dis- 
crepancy between these maps is probably less a matter of fact than of 
emphasis, the later cartographer choosing to ignore the patchy, surficial 
remnants of a once-extensive Cenozoic cover. Under the circumstances it 
is easy to see why Cope assumed the type specimen of Hadrosaurus tripos to 
be a dinosaur vertebra from the Cretaceous “blue marl,” overlooking the 
possibility (now confirmed) that it is a whale vertebra derived from the 
Duplin Marl. 
(3) Milepost (or Mile Board) 49 near Donahue Landing, south bank of 
the Cape Fear River about 15 air miles (24 km) southeast of 
Elizabethtown, Bladen County. A hadrosaurine humerus encrusted with 
bryozoa and Exogyra spat was found at the base of the Peedee Formation, 
evidently reworked from the underlying Black Creek Formation. Detailed
