Evolutionary history of cephalopodsMesozoic - Advanced nautiloids: Nautilaceae • True ammonites
- Early coleoids: Proteroctopus, Styletoctopus, Keuppia, Palaeoctopus, Paleocirroteuthis
- Ceratitid ammonoids • late Nautilida
- Advanced belemnoids: Diplobelids: Diplobelus • Belemnites: Belemnites, Belemnopsis, Belemnotheutis
Palaeozoic - First appearance of long-lasting lineages: Goniatite and ceratite ammonoids • Probable coleoid ancestor Bactritida • Earliest belemnoids: Aulacocerids: Aulacoceras • Phragmoteuthids: Phragmoteuthis
- Early forms: the earliest cephalopod group Ellesmerocerida • Orthocones: Endocerida, Orthocerida, Actinocerida • Brevicones: Ascocerida, Oncocerida • Earliest coiled cephalopods: Tarphycerida • Spirulid?: Shimanskya
- Octopus: Pohlsepia
Cambrian - Earliest unambiguous cephalopods: Plectronocerida (Plectronoceras)
