Perisphinctes Ammonite

Ammonites are among the most recognized fossils, known for their distinctive ribbed, spiral shells shown above. These marine animals inhabited oceans from roughly 240 to 65 million years ago, becoming extinct alongside the dinosaurs. The term 'ammonite' (usually lowercase) originates from the Greek Ram-horned deity named Ammon. They belong to a group of predators called cephalopods, which also includes their modern counterparts—octopus, squid, cuttlefish, and nautilus.
