know that they come from S. Carolina somewhere, and are presumably tertiary.
  They are pale-dark orange-brown in colour and are all laminid. I would
be very greatful if anyone could give me information on where these are
likely to come from, the lithologies/palaeoenvironment and places where I
could get some more."

Your shark teeth are likely to be from:
Miocene: Pungo River Marl Formation (Helvetian).
USA: North Carolina: Beaufort County, Aurora.
The probable species is: {Carcharodon megalodon} (synonyms = {Carcharocles
megalodon}, {Procarcharodon megalodon}).  This species can be distinguished
by the number of serrations along the cutting edge >50 /inch, and the
chevron-shaped "scar" or dark-brown area between the base and the blade.
