Ammonites were ocean-dwelling mollusks that lived from the mid-Devonian (388 million years ago) through the Cretaceous (66 million years ago). The closest living relatives found to day are octopus, squid, and cuttlefish. These fossils are found in sedimentary rock layers of limestone, clay, or shale. The mineral composition of the shell can include iron, manganese, and aluminum, creating vibrant colors. You will receive the exact item pictured.
