The Frankstown locality (Demopolis Formation) of Northern Mississippi was discovered during road construction in
the early 1990's. It was a sandy lag deposit rich in vertebrate remains dating from the late Cretaceous. Sharks were
the most abundant part of the fauna but fish, marine reptile and even dinosaur fossils were found in abundance,
making it one of the most important vertebrate sites ever found in Mississippi. The site was extensively studied and
collected for one year before being buried by highway construction. Small outcrops still remain in creek beds but the
main collecting area is long gone.
