Illinois fossil mammal find.

Looks like a toe/nail or tooth of a large mammal?

An unexpected fossil bone.

Just out walking the dog in a wooded area we frequent. Took a path through the woods have never taken before. Just came across this while walking out of the woods and into a clearing. Was lightly embedded in the soil.

Fossil Collector: Kevinr

Location: Channahon, Illinois

Found in a wooded area about two hundred yards away from the I and M Canal in Channahon, Illinois. There is quite a bit of rock on either side of the canal which was dug out in the process of digging the canal over 100 years ago. This part of Illinois has primarily sedimentary rock. Not sure of the geologic period.

[In response to the editor's question regard the very straight-looking break line on the bone.]

As far as looking like a butcher cut, that was what I was thinking when I first picked it up. But this is most definitely rock. I did push at it with both an awl and knife, and there is no flexibility in that area (or any other) whatsoever. And, the large light looking piece, is sandstone. I think the point that looks like the butcher cut may be just a fracture from where it broke off of the rest of it. Wouldn’t it have taken a long time to fossilize, ruling out any kind of a butcher cut?

What you do you think? Please leave a response and help us identify this find.

    It is not a fossil; just a vagary of the weathering process.
