I am seeing no evidence of bone features, and think this one is a rock.

Unfortunately, this looks like a rock typical of Big Brook.

Note the lack of porous material on any of the faces that would be expected of bone, e.g.:

There are edges on the OP’s piece.

I believe they mean: "none of the edges present look like bone to me", not "there are no edges, looks like bone to me". :D

I decided to polish one end to see the end grain better.  There are pores…. Whereas there is enough of them is up to you guys to decide.  :look:

Caveat emptor:  I am not a bone guy.

 

However, this does not look like fossil bone to me.

Take that with a grain of salt or two.  ;)

 

New Jersey creek stuff is weird. :shrug:

I will also say this…. On many of the pieces you all have said they are concretions they most definitely were after polishing, showing nothing but polished mud or a matrix of tiny pebbles and mud.  But this looks much different than the others.

After polishing, with those colors and the amount of porosity, its almost started to look like metalworking slag to me. I Might be totally wrong about that but it still doesn't look much like bone, sorry.

Would bone have that much color difference?

It looks like slag or volcanic material to me, but I could be wrong.:unsure:

It looks like ironstone rock to me, which can be very tricky because it often has pores that look similar to bone at first.

 

The bright orange tint and the sort of shallow look to the pores makes me lean toward ironstone.  Also, the pores aren't as prolific or uniform as I'd expect in bone.  @IsaacTheFossilMan has provided a good example of porous bone for comparison.

Ok, guys great input from you all and the verdict is more rock. :default_faint:Thank you all for your help.  I’ll keep at it.  And one day:yay-smiley-1:Hopefully sooner than later.

I'm definitely not seeing bone either here.
