Baculites
Baculites were a type of cephalopod that lived during the late Cretaceous Period. They are part of the heteromorph group of ammonites and could reach two meters in length!
These are the ammonites that do not have a planispiral shell. Because of their appearence baculites are sometimes called walking sticks. They grow in flat spirals when they are young. Then as adults the shell grows straight. The baculites we currently have for sale are Baculites compressus Meek. They were found in the Pierre Shale Formation in the Cheyenne Badlands, South Dakota.
