Found these in Girard. Names for the fossils would be welcomed.

Joe, thanks for the link. I'm familiar with that site as I was an anthropology major in my off and on 30 years of attending college. Anthropology is for people who love science but can't do math.

I did some of that chert googling and saw stuff sorta like what I've found but no exact matches. I reckon the geography may have something to do with it.

When I was four we left Texas for Washington as dad got a job at Boeing. We lived in an apartment in Renton, and Mt. Ranier was in my bedroom window, every morning it wasn't raining it was lit in golden sunlight and I thought it was the most beautiful thing ever.

My kindergarten teacher told us Ranier was a volcano. So for a while I thought every mountain was a volcano. Then I learned they weren't, but nobody could tell me why some were and some were not. When I was eight I got a book for xmas that was all about biomes and the animal and plant life that lived in each and the second half of the book was geology. I discovered continental drift and tectonics which explained why were some mountains were volcanic and some were not.

I also discovered I had a hidden learning disability that limited by math ability, including having dyscalculia, the number version of dyslexia. Science subjects like physics and chemistry I just cannot solve, so I opted for anthropology as its relatively math free. Unfortunately the core curriculum has chemistry as a subject I had to take, and I could never pass it so I never got the degree. Then at age 52 I learned why with the LD diagnosis. I have no idea why I just barfed all that up.

Well I am very glad to hear that!
It is a fascinating environment to explore and you are making great progress! There are definitely some major hurdles to get over as far as a positive identification,(ID), goes for your upcoming E-book publication, , but none that should be insurmountable and the research ought to be interesting enough to keep you on the track.

At some point you will probably have to pester some of the professionals in the field in your area for exact species names, but these are largely fossil shapes that we are familiar with and somewhat recognize. Age and depth of the formations has already been a very interesting study to me. And we know it's the Atlantic Ocean and not the Pacific. (HA)

For instance, an initial guess, the group of 'tubular' looking shells in your first picture of the three in your post just before this one look like they ought to be one of the 750-1200 different species of "Scaphopoda, or Tusk Shell.  (In the long haul you will probably need to collect more than one specimen of each because you may have to cut some in two for positive ID's.) Age will be a big factor in species ID but, like I said, atleast we know what ocean. And I have not found anything about them growing in 'clusters' like that?
Here's a link;

And your last three pictures in this last post look like a species of a common snail shell named Buccinum. Very interesting reading on their formation. When that chert formed it was A LOT deeper than it looks today!

Always Shake Well!
