Hi TFF,
I've posted about this Pliocene baleen whale jaw section from Florida before, and its the gift that keeps on giving! Within the fossil there are 2 significant crystalized structures which I would love further clarity on. Are they the remanence of soft bodied organisms burrowing in the bone? Or are these structures mineral deposits similar to those found in shelled cephalopod fossils when water gets into the specimen? Or something completely different? The first specimen is 1.7/2cm in length.
I would love to know your thoughts
