Fully Mineralized Extinct Baleen Whale Jaw Bone Fossil Segment- Not Modern

Massive/Heavy Fully Mineralized (Megalodon Era) Extinct Baleen Whale Rib Bone Fossil Segment- NOT FROM MODERN WHALE. Found firsthand diving an inland River in North Carolina from when half of this history rich state had succumbed to the Atlantic Ocean.

Extinct predators such as Megalodon and other extinct Shark lineages were hunting these whales 24/7. I find Shark Teeth right beside these bones along with some having Predation marks from megalodon kills! Wild, This Fossil is a nice one, I need to learn how to make Shark tooth stands for 2-3.5 inch Great Whites or Megs, would look good on top of some of these bone fossils.
