Peedee Formation

(Redirected from Pee Dee Formation)

The Peedee Formation is a geologic formation in North and South Carolina. A marine deposit, named for exposures along the Great Peedee River, it preserves belemnites and foraminifera fossils dating to the Late Cretaceous (Maastrichtian).[1] The formation is notable for its occurrence of Belemnitella americana, known as the Pee Dee Belemnite (PDB), a long-standing standard in stable carbon isotope research. A single pterosaur femur, possibly an Azhdarchid, from the Peedee formation is one of the few pterosaur body fossils found in Eastern North America.[2]
