Rock talk, second edition: Fossils!
1) Trilobite mold: north Georgia, ~500 million years old
2 & 3) Interpreted storm deposit of several marine invertebrates (2 photos: the original and an annotated one). Annotations: brachiopod shells (S), ostracods (O, look like beans), and bryozoans (B): I think i found these in north Georgia or Tennessee. Likely ~350 million years old.
