The Chesapeake Group has at least 16 different species of otoliths (from bony fish) that fossilized. I still have at least a thousand otoliths left to sort. So far I only have five different species (I think). I have already searched over a thousand otoliths in material brought back in just four trips to this middle Miocene (Calvert formation) site. Here are pictures of the five. If I find any additional species I will post them. 1. Micromesistius cognatus (a genus of cods) 2. Trisopterus sculptus (a genus of cods) 3. Genyonemus sp. (a croaker) 4. Pogonias sp. (a black drum fish) 5. Sciaenops sp. (a red drum fish)
