Fossil Identification Request (Might not even be a fossil, I can't find much on it.)

Hello All, 


This is my first post on Fossil Forum and I have a question on the find during my second ever fossil hunt. The location is a quarry in Northeastern Wisconsin, on the western edge of the Niagara Escarpment I believe. 


I'm not sure, but I think these are fossils? I had to do a double take when I first saw it, as I though they could be from drilling into the quarry wall or something, but I found 4 or 5 of various sizes with the biggest one that was exposed to the face of the quarry being about 2 inches in diameter. I also was wondering if 2 of the photos (6 and 7) were a stromatolite? I found all these in about 3 hours, along with a big coral. So I will be going back this weekend :D

Welcome to the Forum. :)


The first few images look like the imprints of Orthocone nautiloid cephalopods.

Some of your other images may be corals, but with nothing for scale in the images, it is difficult to be certain.

I think that one of the middle pictures looks like a possible stromatolite.  Please number your pictures so we can all talk about the same piece at the same time.
