Fossil shells collected during excavations in Toca da Esperança, BA, were identified on morphological grounds as: Artemon intermedius intermedius (Albers, 1857); Gastrocopta (Privatula) corticaria (Say); Bulimulus (Rhinus) heterotrichus (Moricand, 1836) and Polygyratia polygyrata polygyrata (Born, 1780). Bone samples found associated with these shells were dated by the Uranium - Thorium method as being between 204,000 and 295,000 years old (Middle - Upper Pleistocene). Species of the mastofauna also found associated, on the other hand, were identified as being of the Upper Pleistocene or even of the beginning of the Holocene. The material studied here was not dated.
