Yorktown Formation

Why is it that in North Carolina, the Yorktown formation seems to be full of Shark's teeth but in Virginia they seem to be comparitively rare. I live in Yorktown and feel a bit jipped. Drew

Re: Yorktown Formation

Hi Drew, I think its because the ocean conditions around the Aurora area were more ideal that those around the VA area. Not that they weren't good in VA (else there would be NO teeth there), they were just too good to resist for hungry sharks around current day NC. There was actually Yorktown down here in SC, too, at one point in the distant past, but with all the erosion caused by the incoming/outgoing coastlines we had (there are 5 distinct coastlines in SC since the Eocene), the Yorktown was completely eroded and its fossils redeposited. Not only that, but the inland areas REALLY got the shaft - all the miocene fossils that used to be there (experts say that they could have been as far inland as Columbia) were washed down to the low country. Isn't that a kick in the teeth for SC inlanders?? dw

Re: Yorktown Formation

I have been reading with amusement the questions and "expert" explanations on this forum for several months. The Internet is well known for it's inaccurate content and this forum is not exempt. Contrary to statements made, the Miocene Yorktown Formation does exist in several exposures in South Carolina. It's just called something different; the Duplin Marl Formation. North of the Neuse River in NC it's called the Yorktown; south of the Neuse and in SC it's called Duplin Marl. There are some great exposures in Sumter county. In addition, all the Miocene fossils have NOT been washed away to the low country. There are several undisturbed Miocene formations stretching from the coast to up near Richland County. The Edisto, Marks Head and Rudd Branch Beds along with Duplin Marl are some examples. BTW, please don't use Elmer's Glue mixed with water on any of your shark teeth. This junk contains acids that will degrade the internal structure of your tooth. It will also yellow over time and if layered on, will crack and peel away.

Re: Yorktown Formation

I don't think anyone here ever claimed to be an expert. If you see inaccuracies, please point them out. We're all here to learn. If we knew everything, then we wouldn't need to participate in this forum, would we?
