Biology:Fresvillia
From HandWiki
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. An indeterminate species of Fresvillia may have briefly survived the K-Pg mass extinction event.[1]
Baculites, Boehmoceras, Eubaculites, and Lechites, are among related genera.
