Aurora, NC
Aurora, NC is a quiet town just south of the Pamlico River in rural North Carolina. It has
a population of well under 1000. Although this is a small rural town, there is a rich geologic
history lying beneath Aurora. This makes it the capitol of the world for many fossil
enthusiasts.
The Potash Corporation of Saskatchewan (PCS) is currently operating a large phosphate mine
in Aurora. In the process of prospecting for phosphate, the mine digs through several
fertile fossil-bearing formations. This gives paleontologists and fossil enthusiasts a
unique opportunity to collect and study this rich fossil bearing material.
Aurora has a Museum devoted to the geologic diversity found under the town. The
Aurora Fossil Museum
contains a wide array of fossil displays collected from the PCS phosphate mine.
These displays include numerous shark dentitions, including the jaws of a Giant Megatoothed
shark, to a walrus skull and a whale skull. The museum also has a room devoted to native
American artifacts from the area. Also, the PCS mine dumps piles of fossil bearing sediments
at the museum for visitors to search through.
Brief Geologic History:
Throughout the Tertiary, North Carolina was part of the Albemarle Embayment. The Albemarle
Embayment was one of the large embayments of the Atlantic Coastal Plain. The other was the
Salisbury Embayment, which presently takes the form of the Chesapeake Bay. The two embayments
are collectively called the SAE (Salisbury and Albemarle Embayment)
Similar to the Salisbury Embayment, this embayment may have acted as a calving ground for
whales. The embayment housed a large diversity of life, including reptiles, and all kinds
of fish, including sharks such as C. megalodon. It housed numerous marine mammals including
large baleen whales, porpoises, seals, and sea cows. Sea going birds also thrived in this
embayment. Also, remains of land mammals that washed out to sea can occasionally be found
including horses and camels.
Throughout the Tertiary, sediments and animal remains were deposited into formations. The
two most popular formations (fossil-wise) are the Pungo River (Miocene) and Yorktown (Pliocene).
Many other formations were also deposited ranging from the Eocene formations to Pleistocene
formations (James City Formation). The PCS Phosphate mine digs through these formations
in search of phosphate that has accumulated in this ancient embayment.
