Baculitidaeis a family of extinctammonoidcephalopods that lived mostly during theLate Cretaceous,and often included in the suborderAncyloceratina.[1]
Baculitid genera are characterized by a small to minute initial coil of about two whorls followed by a long straight or slightly curved shaft. Genera are distinguished on the basis of size, general shape, particulars of the suture, and ornamentation. They can reach lengths of 120 cm (47 in) or more.[1]
Baculitids are found worldwide in deposits from the upperAlbianto theMaastrichtianages.[1]Related families are theAnisoceratidae,Diplomoceratidae,Hamitidae,Nostoceratidae,andTurrilitidae;all of which along with the Baculitidae are included in the superfamilyTurrilitoidea.[2]

- Baculites
- Boehmoceras
- Eubaculites
- Fresvillia
- Lechites
- Pseudobaculites
- Sciponoceras
- Trachybaculites
- Tuberosciponoceras
