Dactylioceras Ammonite Cluster

This fossil cluster features multiple preserved ammonites of the genus Dactylioceras, an extinct group of marine cephalopods related to squid and octopus. Known for their tightly coiled shells and strong ribbing, these ammonites lived in shallow seas. Fossils like this formed when they accumulated on the seafloor and were quickly buried by sediment, allowing for their preservation. Dactylioceras is an important index fossil for dating Early Jurassic rock due to their rapid evolution and wide distribution. This piece offers great visual texture and composition, ideal for collectors or educational displays.
