Bone Fossil?

[vonfatman]

Found this while chasing rocks.
I threw it in the bucket and brought it home.

Any thoughts as to :
-if it is a bone fossil?
-what might it have been from?

Thank you.

I’m probably wrong, but it has the look of bone to me. Id guess fossilized bone. 50/50

Hmmm....it looks like it may stay a mystery.

Interesting. With all of those parallel structures radiating to a surface covered in tiny pores (see detail from one of your pictures below), I would be sure it's not bone.

That kind of structure would be consistent with a fossil sponge in the territory of stromatoporoids. This is Labechia carbonaria, for comparison only rather than as an ID match:

That looks pretty similar. I was thinking coral, not bone, but couldn't find any that looked quite like that.

It is a unique to me rock, It was easy to pick out and pick up but not easy to i.d.

That fossil sponge looks to me to be very very close... in fact, I would go with that over bone.

I appreciate the pics!
