Fresvillia is an extinct cephalopod genus belonging to baculitid family of the ammonoid order Ancyloceratida that lived during the Late Cretaceous, found in France. Baculitids are a kind of heteromorph ammonite characterized by a straight adult shaft, often preceded by a small coiled juvenile portion.
Baculites , Boehmoceras , Eubaculites , and Lechites , are among related genera.
An orthocone is an unusually long straight shell of a nautiloid cephalopod. During the 18th and 19th centuries, all shells of this type were named Orthoceras, creating a wastebasket taxon, but it is now known that many groups of nautiloids developed or retained this type of shell.
