This ‘fossil’ was found on a river gravel bar in Southern Minnesota. Sedimentary layers in the area include Wisconsin lobe glacial till and cretaceous mudstone/sandstone.

I am totally stumped. eems to be rock. I am totally stumped.

This vertebra was found at an estate sale in a box of rocks in Minnesota. It is partially mineralized, but I don't believe it is mineralized enough to be much older than Pleistocene. I realize it is fairly damaged but does anybody have reasonable guess as to what it might be from?

Also the m3 here looks two-lobed. Can someone clarify?

Found on river gravel bar in Sothern Minnesota. I know its a partial bovid skull - any ideas on species? I'm thinking young male bison.

These are two fossils of the same species collected at the Long Pond Road Site along the Erie Canal in Greece, New York. They are from the middle Silurian Rochester shale. These were collected last winter, and I have since been unable to identify them. Both are no greater than 3cm in length. Some interesting fine detail is visible on the first specimen. The American dime is 1.8cm in diameter.

This is a fossil I collected at the Long Pond Road Site along the Erie Canal in Greece, New York. It is from the middle Silurian Rochester shale. Some interesting perpendicular lines can be seen along the edge of it. I have looked for other fossils similar to this one and have found nothing. The American dime is 1.8cm in diameter.
