Hey! I found this fossil in southwestern Ohio, I don't know which period it is from but as you can tell there are quite a few shells and coral embedded around it. I don't know much about fossils but my guess is it's part of the head or rear of a trilobite? I estimate it's about 3/4 inch in length. I also noticed there's another one embedded deeper to the right of it. I honestly have no idea about this one, can any of you help me out? Thanks
