answer:There are federal and state laws about what kind of animal parts you can have in your posession. You must have a permit to have any part of a Bald or Golden eagle, for example. As far as I know, the only restrictions are for federally or locally protected or threatened species. Please keep in mind zoonotic diseases, though (rabies, etc). And as an aside, ant hills are great for cleaning up skeletal remains. Just drop the remains on the hill, and check back in a week or so.
