Bone?

Really interested in this stuff but super new to it. Could this be bone?

One of the great fakers, an iron concretion - not a bone.

Thank goodness. I was hoping bone couldn't look like this.

@carley808 Welcome to the hobby!  You have a good eye for unusual material. I agree that it appears to be geologic in origin, but I would have picked this up for a much closer look as well.
