Bone? ID?

[Further]

My friend and I found this by Lake Somerville in SE Texas. My untrained eye thinks it looks like bone, definitely mineralized, but we have petrified wood in this area as well, which I  am used to looking like everything under the sun.

 

Bone? Any guesses what from if so?

 

Thanks in advance,

Brian

Bone, I think. Looks modern to me.

Thanks, feels heavy for it's size, but I measured the hardness and it is somewhere between Mohs 3.5 and 5.5, so probably bone(5), but i appreciate the confirmation.
