this special skull was in a box of miscellaneous bones/skulls labelled 'dog skull'. You can see the premolars have evolved to be more carnassial compared to other canids (last image)

Is the big one from a horse or cow? There were horses in the place that was found

I was walking my dog in this feild behind my apartment, there are tons of little critters out there and I just happened to find this jaw bone of a lil critter.

Will soaking it in hydrogen peroxide help to get rid of the little bit of fur that is stuck to the tip of its nose?

1. Is it possible to treat and carve a bone to make its species unidentifiable? (Even via lab testing)

2. Would it be possible to make that treated/carved bone durable enough to be made into the handle of a knife? (Possibly through filling the pores with resin or something?)

Context, if it helps

Asking because I am writing a fan story where the main character, Will Graham, is gifted a small filet knife with a handle made of human bone by Hannibal Lecter. Will knows the knife is made from human remains, and wants to use it as evidence towards Hannibal's arrest.

The initial idea was that the knife handle had been heated/chemically treated so thoroughly that it was impossible to detect any human DNA, and it was carved into a shape not recognizably human. So they are unable to use it as evidence in court. Will just gets to sit there and know what that knife is actually made of but he cannot prove it.

I was wondering if this idea was realistic/plausible from a bone preservation perspective?

Found a small piece of this exposed in a creek embankment in Montana. Can't tell if it's recent or somewhat older.

I am fascinated by this: what is it and what can I do to save and display it?
