I recently found these fossils in a ditch of a hay field on my grandmothers marina on the shores of Lake Ontario. Any information on them would be welcomed :) thank you!

Well, the spiral one is a gastropod. The other thing looks like a trilobite, but not one that I'm familiar with. I'll try to do a little more research. What locality were these found? I don't need an exact location, but Lake Ontario has a lot of New York touching it, a better idea of where will help to narrow down the possibilities.

Thanks for the info! This was found on the shores just outside of the town of Cape Vincent, you can see Fox Island from the shore.

So I think that's the Trenton Group in that area, Rockland limestone perhaps? Which would be middle Ordovician. I didn't notice it before, but there are actually two gastropods right next to one another facing opposite directions, that's pretty cool! I have no idea what that trilobite might be, but I'm quite curious. While I continue to research on my own, I am going to call in the big gun—perhaps Scott can offer some direction on this one, @piranha. Not even 100% sure it's a trilobite. I see reasons to think it is, as well as reasons to think it's not.

You are a living encyclopedia. I don't know how you do that so quickly. I hadn't even successfully located a paper describing the trilobites from that formation yet!

Nice little trilo-bit! The Gastropods remind me of Hormotoma but take this with a grain of NaCl as I’m no snail expert.
