This lot of fossil specimens was recovered from deposits in Central Florida. Three of the specimens are Miocene era marine fossils and the fourth specimen is from a Pleistocene deposit. Each of these pieces are "trace fossils" that are imprinted on the host rock. I have not identified these pieces, but three are clearly marine organisms.
Refer to the photos. The black centimeter cube is shown for scale and is not included. You are purchasing all of the specimens shown.
