 The goniatite is an extinct cephalopod mollusk, a cousin of the ammonites. It lived in the seas approximately 400 to 250 million years ago, from the Devonian to the Permian periods. Its name comes from the Greek "gonia," meaning "angle," referring to the zigzag sutures of its shell.
 Varying in size, generally between 5 and 15 cm, the goniatite had a planispiral shell rolled up on a single plane. This shell was composed of chambers separated by partitions, the last of which housed the animal. The empty chambers served as a float, allowing it to move through the water.
 Goniatites were carnivorous predators, feeding on small marine animals. They were an important part of the marine food chain of their time.
 Today, goniatites are fascinating fossils found in sedimentary rocks, providing insights into the evolution of marine life and past environments.
