Is This Fossilized Bone, Or Just A Rock?

[claire01]

I am completely unfamiliar with bone material (except fish bones) and was wondering if someone could tell me if that's what I have here or if it's just a rock. This piece is Approx. 2.5" x 1.5". Cretaceous, Eagle Ford.

Thanks, guys.

Based on pattern and texture o the area I've circled, I think it's bone:

Possibly reptile???

Oh that's exciting, thank you Auspex!

It looks like a piece of bone to me as well.

Looks good, especially the area Auspex circled. I'd search that area closely, particularly for more pieces. It doesn't look like it experienced much weathering or tumble/polish.

Thanks Richard-what's it likely to be, Mosasaur? Or is that impossible to tell? And by the way, I heard back from the Corps, no access :/

And CH4ShotCaller: I will be going over that spot with a fine tooth comb!

Thanks for your help!

Being found in the Britton as it looks like it was, I would wonder aloud if it may be a plesiosaur bone piece?

Thanks Richard:)
