Abstract

A high-spired septate gastropod, Fletcherviewia septata n. gen. and sp., occurs in a distinctive faunule at the base of the Middle Devonian Fanning River Group, within the Burdekin Subprovince, near Townsville, North Queensland, Australia. This species is one of four large, thick-shelled gastropods associated with sandstone and sandstone–limestone facies; the sediments are interpreted as shallow marine, nearshore, mobile sand bars on a moderate-energy carbonate–clastic shelf. Strategies for the algalgrazing snails on the turbulent substrate are rolling for compact robust forms and anchoring, using the wide carina, for forms such as Fletcherviewia. Septation in Fletcherviewia is rationalized in terms of the ability to vacate early whorls, thus reducing body volume and avoiding any detrimental effect as a result of loss of early-formed whorls.
