I got this a few years back in Canaan valley (if memory serves) West Virginia before With a bunch of other fossils. I bought it, as this was before I had learned that you could actually legally hunt fossils yourself (if I had known, that valley would have been scoured for fossils, as its geology is apparently amazing). I assume this was from the area, although this could be incorrect. This one caught my eye because of its curvature, is this the way it was when it was alive or is it just disarticulated septa? Is it possible to get a close ID on this orthocerid?
