1 Massive Authentic / Real / Extinct /Fossilized Mysticeti Rib Bone, NOT MODERN
1 Massive Authentic/ Real / Extinct /Fossilized heavy Mysticeti Rib Bone with Yorktown sediment Matrix stuck to the bone, beautiful iron/black/brown coloration, NOT MODERN, Found firsthand diving an inland River in North Carolina, these fossils were literal Megalodon food, I can't say the exact type of animal it's from on Etsy because they think it's from a modern animal, but it's the largest animal ever in the ocean still to this day. This rib bone is from a "Mysticeti", if you google it it will come up right away.
