Rover Posted July 15, 2010 Share Posted July 15, 2010 I recently went fossil-hunting at Green Mill Run, as some of you may know, and, while I have heard a lot about the fossil-rich shell-bearing layer of sediment there, I've never heard anyone say how old it is, so I was wondering if someone here might know.

I guess they are from plio-pleistocene (James City or Waccamaw formations).

tracer Posted July 15, 2010 Share Posted July 15, 2010 i've never been there but people have posted pics of exogyra oysters from there, so there's an upper cretaceous element there also. like so many waterways, i think you have a mix of older and younger stuff that's been eroded out and scrambled together.

It is the Rushmere Member of the Yorktown formation, Middle Pliocene.

PaleoRon Posted July 15, 2010 Share Posted July 15, 2010 The shell bed in GMR that sits on top of the Cretaceous is a lag/reworked deposit that contains complete shells from at least two formations. I have found a decent Yorktown formation Ecphora sitting right beside a James City formation Pterorhytis. It appears that the layer formed as the James City sea "stirred up" the earlier Yorktown formation. Link to comment Share on other sites More sharing options...
Rover Posted July 15, 2010 Author Share Posted July 15, 2010 Alright, thanks. That means I'll have to wait until I can post pictures of my finds to know the ages of individual specimens, and as I always have to borrow a camera from someone, it might be a couple of days, but at least I have a general estimate.
