Definition of goniatite in English:



  • An ammonoid fossil of an early type found chiefly in the Devonian and Carboniferous periods, typically with simple angular suture lines.

    Compare with ammonite and ceratite
    • ‘Early ammonoids or goniatites may have simple zig-zag sutures, but they become increasingly complex from the Triassic to the Cretaceous.’
    • ‘Good material showing sutures and growth line ornament are required for detailed determination of goniatites.’
    • ‘The richly fossiliferous Namurian bed is packed with both brachiopods and goniatites.’
    • ‘The taxonomically diverse goniatites dominated the Carboniferous-Permian ammonoid fauna.’
    • ‘Carboniferous goniatites as a group appear to be relatively cosmopolitan.’


Mid 19th century: from modern Latin Goniatites, from Greek gōnia ‘angle’.
