Description
Fossil Identification
This listing features a Didymoceras nebrascense heteromorph ammonite fossil, identified as Upper Campanian, Cretaceous. Didymoceras is a notable ammonite genus associated with the diverse and highly varied ammonite faunas of the Late Cretaceous. The term “heteromorph” refers to ammonites with shell forms that depart from the more familiar tightly coiled, planispiral shape. These unusual forms are of particular interest to collectors because they demonstrate the wide range of shell architecture developed by ammonites during their evolution.
Geological Context
The specimen is identified as Upper Campanian, Cretaceous, placing it within the later part of the Campanian Stage of the Cretaceous Period. Ammonites were extinct marine cephalopods related to modern nautiluses, squid and cuttlefish. Their coiled or irregularly shaped shells are among the most recognisable fossils in the geological record, and their evolutionary changes make them important subjects for fossil collectors and palaeontological study.
A heteromorph ammonite such as Didymoceras nebrascense offers a distinctive alternative to conventional ammonite specimens. Its identification makes it suitable for a collection focused on Cretaceous fossils, ammonites, heteromorph cephalopods or unusual fossil forms. It may also appeal to educators, students and anyone interested in the diversity of ancient marine life. The geological identification supplied for this fossil is Upper Campanian, Cretaceous, and the location supplied is S. DAKOTA, USA.
