Baculites (which means "walking stick rock") was a genus of ammonite that lived during the late Cretaceous period. It was heteromorphic: in its juvenile stages it had a coiled shell; as an adult, it was straight-shelled, tube-like that grew up to approx. 2 meters long (but some later forms had a cork-screw shape). Baculites was a wide-spread marine cephalopod mollusk that may have lived in colonies on the sea floor.
