Absolutely, the bones that get fossilized are the ones that somehow keep just enough integrity to survive the long march of time. It’s like each bone does a quiet negotiation with the elements—mineral-rich tissues, protective periosteum, everything that slows down decay. In the end, those robust, densely packed cortical bones end up in the record while the flimsy, porous ones fade into oblivion. It's a silent strategy, but one that really keeps the story alive.

Exactly, it's the same principle as when you stack plates. The denser, more compact bone resists both gnawing and weathering. Those strong, dense cortices keep the structure in place long enough for mineral replacement to take over. So yeah, the toughest bones are the ones that make the final record.

Exactly, each sturdy bone is a silent champion, holding the tale together, one robust section at a time.
