Bone with Bite Mark?

[TonyC]

I'm looking for the collective experience of this group to help me determine if this is a bone fragment with a bit mark in it. Or is it just a rock.  Here's several photos of the piece in question.  Hopefully the quality is sufficient to make a determination.

Where was this found?

It doesn't look like bone to me, but bones are not my area of focus in fossils.

I'm not seeing bone either.

Looks like a piece of mica schist to Me.

Were it a piece of bitten bone (and I do not think it is, for lack of cancellous cellular structure), I would expect to see signs of crushing or splintering at the site of the bite.

looks like a metamorphic rock to me

Okay, looks like the consensus is not bone.  Oh well.  Thanks to all for sharing.  Took it out of Big Brook, NJ.

There are often concretions in the NJ streams that can resemble bone. Most bones in NJ Cretaceous streams are from turtles and often are black and look like cheese due to their porous nature. Some bones are from dinosaurs and they somewhat resemble petrified wood and have cellular structure. I think in your case it is a concretions, but hopefully you can find some actual bone soon.
