    Collection site on the Great PeeDee River.  Described by early authors as Duplin Formation but is more likely Raysor based upon description of the formation in

    Fabulous! Is this upper Goose Creek Limestone?

    Hi Don--It is either Upper Goose Creek or Raysor.  Very limey mostly unconsolidated and found with calcitic mollusks.  The sediment is very similar to the Raysor from Cross.  In the referenced paper the authors state about Pliocene sites on the PeeDee "equivocal percentage favors Duplin, DICE favors Raysor, but the commonality with the Goose Creek Limestone and the Miocene [Pliocene] rather strongly favor Raysor."

    Thanks Mike. I have the Tulane paper and guess the different between the Raysor and Goose Creek is gradational. Probably an environmental difference as there is Raysor at Elizabethtown in the borrow pit (as well as the regular "Etown beds") but it's the thick pecten bed of the UGCLS just down the road south of Etown.
