[Rockhounds] fossil ID Request

[J. R. Hodel]

Hi:

A friend at work found a nice chert in her driveway with a little vug and a (probably marine) fossil in it.  If you look at the rock with a 10x loupe you can see numerous micro-fossils in the chert.  I'm not much of a fossil guy, but I know there are several on the list.  She was thinking an archimedes of some sort, but I think the layers are too close for that, the best archimedes I've seen were about a twist each 1 or 2 cm or thereabouts, this has a layer each mm or close to it.

I have a pretty good 60mm Micro Nikkor lens, and took a reasonable picture of it, which I've reduced to a 98k file for emailing.  If anyone wants a look, let me know your email.  

Given that this driveway is in Charleston, WV, I expect the crushed stone on it came from somewhere on the Ohio River, as most of the aggregate around here is from Shamblin Stone, and they have all their rock barged in. 

Thanks in advance!
