Thought this could be a clam, but not sure due to the extension of shell. Maybe a brachipod?© Tammie Harper

here is some thing i have been wondering for the last few days. i have found that most ancient cephalopods are divided into nautiloids (cephalopods with shells) and coleoids (cephalopods without shells). but i recently read that a fossil of the orthocone Michelinoceras was found with 10 arms and a radula with 7 teeth per row. arent those coleoid traits? i know that an ammonite fossil was found with those features and was thus determined to be a "coleoid". is it possible that this grouping is arbitrary and that many more supposed nautiloids are coleoids that just happen to have shells?
