Can anyone identify this 1ish inch shell that is agatized that dates back 23-24 million years ago found in Tampa Bay Florida?
Does anyone know a paper that references these?
I use muriatic acid to clean limestone chunks of agatized coral stick. Many times I come across other items like this. Corals and shells.
Just trying to get a better idea of some of the items I found. This was left for me by mother nature on a storm Christmas eve 2020.
