Cleoniceras, belonging to the Ammonitina suborder, are one of the best known and most studied ammonites in the fossil record. Their shell is compact and rolled, with characteristic ribs that develop in a regular manner. These fossils represent a point of reference for the dating of Cretaceous sedimentary rocks and contribute to the understanding of marine biodiversity of that era.
