North Carolina Bivalves and a few other things

[sixgill pete]

The Sunday of the weekend before Hurricane Mathew came a calling, a friend and I decided to spend the day fishing on the Neuse River in eastern North Carolina. WE had a pretty good day fishing, caught lots of small puppy drum and stripers. No keepers but fun to catch. About halfway through the day we left the creek  we were in and headed back into the main river. Heading from the Cherry Point area heading over towards New Bern. A mile or so up we saw fish busting all over the surface on the Flanners Beach side of the river but not quite that far. We motored towards them and for an hour or so caught stripers on almost every cast. As we were leaving we noticed there was a small cliff eroding out and decided to check it out. We beached and found small gravel on the beach in a strip about 40 or so yards in front of the eroding cliff face. Now, I have been on this river my whole life, but have never noticed this area before. We started finding bivalves almost immediately. We also found some small worn shark teeth, a nice burfish mouth plate and some possible small bone material. 

I am trying to pinpoint down the age of this exposure. There is Pleistocene Flanner Beach Formation and James City Formation nearby. James City is earlier. There are also Pliocene deposits. Possibly Yorktown, Chowan River or Duplin. The reason I am adding all of these is because of the bivalve ID's if I have them right. So any help is much appreciated. 

 

Please correct any incorrect ID I have as I am still learning how to properly ID Molluscs.

 

The first is a bivalve that according to my reference is known from the Pliocene Duplin Formation; Glycymeris subovata

 

 

Next an oyster Myrakeena sculpturata, from the Chowan River Formation (Pliocene) by my reference.

next up, Anadara transversa from the Pleistocene Flanners Beach Formation

 

 

then, Rangia clathrondonta from the Duplin Formation.

Myrakeena lawrencei, James City Formation.

 

 

Next up is a small piece of what I think is Chesapecten septenarius. It is Pliocene.  I know it from the Yorktown. I am not sure if it is known from the Chowan River or the Duplin.

next is two I could not ID.
Help!!! about 7/8 inch

 

 

and next about 3/4 inch

 

 

a cool tooth in matrix, even if it is really worn. Probably some type of sand tiger, but to worn to ID past that.

I am trying to see if I have my ID's correct and also trying to figure the age of this deposit. Thanks for looking.
