Unknown Bone, Hawaii

[bencoulter]

A few months ago, I encountered this peculiar, potential, bone along the shoreline of the Big Island of Hawaii. I noticed it’s porous material, but was puzzled by its overall appearance. I’m not sure if is fossilized or not; however, it is slightly larger then a standard quarter. Thanks for your time!

Welcome to the forum !

 

Such a nice example of a Burrfish ( Chilomycterus sp.) mouth plate. We find fossil examples here up and down the East Coast ... you may have found a modern version ! They still are out there swimming in the ocean today.
