A geologist thinks this could be bone? Need help to ID this crystallized discovery.

[HaidaGwaiiBeachFinds]

Hi Everyone,

 

This is a beach-find from Haida Gwaii, Canada. I realize it’s not a fossil, but perhaps because someone has already said it’s most likely bone- I was looking for more help to narrow (or marrow!) it down. 

 

Approx 20cmx20cm

 

Thank you!! I appreciate your input.

From the pictures given, it doesn’t look like bone although I’m interested to see what’s on the bottom of the last picture. 
 

Mineral maybe?

Those look like maybe Calcite crystals.

Have you attempted to drop a little bit of vinegar on it to see if it reacts ( bubbles )?

I can see a geologist having experience with bones that (sort of) preserved in this manner only with context to provide evidence of bone in that case.

It's not much but maybe it's a nudge toward plausibility.

Could also be kryptocrystalline quartz. Don't see any bone substance there in the photos though. Where does your geologist see it?

Here’s the bottom! Jury is still out on this one. I also just added more photos above, better quality thank this.

Exactly what I was thinking. It was a self proclaimed geologist online. Another front runner is Misty Agate, but for an amateur it’s too difficult to make a ruling!

No bubbles!

I'm going with Agate!

No bone imho. 

Some Stuff of mineral/Rock as described already.
