These are the last of the teeth that I have been profiling that came in a bag of mixed shark teeth labelled as "Belgrade Quarry, NC". The two teeth shown here were a bit easier to ID for me although I still needed to get confirmation from the Fossil Forum. I recognized these teeth as belonging to a Sand Tiger shark, but the Fossil Forum member "Sixgill Pete" was able to further ID them as Carcharias cuspidata which is very common in the Belgrade formation.
Specimen #1 -
The Belgrade formation is dated to the early Miocene epoch of the Paleogene period.
