Piper,

Look HERE for some line drawings of Devonian fossils.

Here's an image of a few Devonian representatives.

You may have a gastropod (snail) or other fossil, but unless this is an unusual brach it shouldn't have spines. However note that image #11 shows one such brach.

Careful, I'll turn you into a paleontologist and we can't have that! :grin:
