ceratite /ˈsɛrətʌɪt / /ˈsɪərətʌɪt/nounAn ammonoid fossil of an intermediate type found chiefly in the Permian and Triassic periods, typically with partly frilled and partly lobed suture lines. Compare with ammonite and goniatite.- Typified by the genus Ceratites, order Ceratida.
The suture lines of ceratites are less complex, and those of goniatites even less so than ceratites....- Consequently, sutural nomenclature of Permian ceratites and Mesozoic ammonoids has to be modified.
- At last tracking structures indicate different viscoelastical properties of the septal mantle in goniatites, ceratites and ammonites.
Origin Mid 19th century: from modern Latin Ceratites (from Greek keras, kerat- 'horn') + -ite1. |
