Ammonoidea
Ammonoids su grupa izumrlih morskih mekušaca u potklasi Ammonoidea iz klase Cephalopoda. Ovi mekušci, koji se obično nazivaju amonitima, bliže su povezani sa živim koloidima (tj., hobotnicama, lignjama i sipama) nego sa nautiloidima sa ljuskom kao što je živa vrsta Nautilus.[1] Najraniji amoniti pojavili su se tokom devona, dok su poslednje vrste nestale tokom ili ubrzo nakon izumiranja krede-paleogena.
