Many thanks to Vahe Demirjian for bringing the publication from
earlier this year to my attention. Unfortunately, is it not yet posted
in electronic form that I can find. I don't have a table of contents.
However, here is what information I have found:


David R. Schwimmer, Albert E. Sanders, Bruce R. Erickson & Robert E.

A Late Cretaceous Dinosaur and Reptile Assemblage from South Carolina, USA.

ABSTRACT

A new assemblage of Late Cretaceous dinosaur and reptile remains from
Campanian and Maastrichtian deposits of eastern South Carolina is
described. Six of the fourteen localities include new occurrences of
theropod and hadrosaur dinosaurs, substantially increasing the known
localities in the eastern United States that have produced dinosaur
remains. Dinosaur remains were associated with abundant bones and
skull fragments of the marine pleurodire (side-necked) turtle
Bothremys, as well as marine and freshwater cryptodire turtles,
including species of Adocus, Osteopygis, and Trionychidae, and, among
the chelonioids, Toxochelys, Peritresius, Euclastes, and a new species
of the dermochelyid Corsochelys described herein. Other reptilian
remains in these localities are three identifiable crocodilian genera
(Deinosuchus, Bottosaurus, and Borealosuchus) and an indeterminate
longirostrine, mosasaurs, plesiosaurs, and a teiid lizard. This
assemblage overall consists of fragmented bones and isolated teeth,
characteristic of lag deposits, containing admixed marine and
non-marine taxa, dominated by turtles and crocodilians. Taphonomic and
paleoecological aspects of the fauna are discussed, including
coprolites and bite marks on bones.

PREFACE

This volume describes a new assemblage of Late Cretaceous dinosaur and
reptile remains from Campanian and Maastrichtian deposits of eastern
South Carolina. Six of the fourteen localities include new occurrences
of theropod and hadrosaur dinosaurs, substantially increasing the
known localities in the eastern United States that have produced
dinosaur remains. Dinosaur remains were associated with abundant bones
and skull fragments of the marine pleurodire (sidenecked) turtle
Bothremys, as well as marine and freshwater cryptodire turtles,
including species of Adocus, Osteopygis, and Trionychidae, and, among
the chelonioids, Toxochelys, Peritresius, Euclastes, and a new species
of the dermochelyid Corsochelys described herein. Other reptilian
remains in these localities are three identifiable crocodilian genera
(Deinosuchus, Bottosaurus, and Borealosuchus) and an indeterminate
longirostrine, mosasaurs, plesiosaurs, and a teiid lizard. This
assemblage overall consists of fragmented bones and isolated teeth,
characteristic of lag deposits, containing admixed marine and
nonmarine taxa, dominated by turtles and crocodilians. Taphonomic and
paleoecological aspects of the fauna are discussed, including
coprolites and bite marks on bones.

The important but seldom-mentioned role that South Carolina played in
the early history of studies of North American Cretaceous deposits and
faunas is outlined, and the stratigraphic settings of fourteen
localities are analyzed. Of the six localities where dinosaur bones
were found, two principal sites yielded the majority: one at Stokes
Quarry, Darlington County, in the mid-Campanian Coachman Formation;
the other at Kings tree, Williamsburg County, from the late Campanian
Donoho Creek Formation.
