Over the years we've offered many hundreds of glyptodon scutes, a small handful of glyptodon claws, and one glyptodon toe bone - and ZERO limb bones. Outside of scutes the number of glyptodon post cranial elements we've ever offered could easily be held in one hand, that's how rare glyptodon bones are!! This is the distal end of a humerus. Yes, it's just a broken end of a bone, but when it comes to glyptodon bones you take what you can get. It is so well mineralized it is literally like a rock. Great representation of an incredibly rare fossil. Great price for the rarity.
