Desmond T. Donovan
Bagnolites stuarti gen. et sp. nov. is described from the lower part of the Lias Group (Lower Jurassic, Upper Sinemurian, Obtusum Zone, Stellare Subzone) of the Dorset coast. It is characterized by an involute shell with smooth, trigonal whorls and a distinctive suture line. Its systematic assignment is uncertain but it may be a derivative of the family Arietitidae.
