Does anyone know what this is?

This is something that Ive had for years now. It either came from Colorado, St. Thomas, or Florida. It seems to be either bone or cartilage. Does anyone have any ideas as to what exactly it is? Thanks

Its the lower left mandible of a bird species of some sort. Note the spongy texture of the bone, typical of the lightweight qualities of bird bones.
In the first photo, the topmost curved bony projection is a part of the hinge that connects to the skull.

Well its definitely bone (kind of like a bird's beak). To know for sure would probably require some testing and expert analysis.
