First Fossils of 2014

I went on a hike today and found some fossils in these rocks.
Are this fossils or impressions?
I don't know much about them but I thought someone might like to see.

Thanks for looking

They appear to be chunks of encrinal limestone, or possibly chunks of chert deposited within limestone. The fossils are crinoid stems, each individual donut-shape section of stem is called a columnal. These are likely to be Mississippian in age.

Here is a generalized map of my area. You could be correct Harry. Thanks for the reply.
