Scientists believed that ammonites, like modern cephalopods, had soft body tissue with tentacles attached to their heads for catching prey. Purposely incompatible with the masses, it clearly lends itself to the underground, pushing its charisma in the direction of the label's earthy vociferation. Fossil evidence indicates they had sharp, beaklike jaws to snare prey such as plankton, crustaceans, and other ammonites. Ammonite fossils are traditionally illustratedupside down with the body chamber shown at the top.
