“…Although most of the coastal shellmounds consist of marine mollusk shells, terrestrial species are also found composing the archaeological context (Figure 1) in many of these sites alongside the Brazilian coast (Table 1). Moreover, land snails are present in non-coastal sites throughout the Brazilian territory (Prous 1986; Mello and Coelho 1989; Moreira et al 1991; Magalhães et al 2001; Brentano et al 2006; Rogge 2006; Rosa 2006; Teixeira 2006; Gernet and Birckolz 2011; Agudo-Padrón 2012; Bandeira 2013; Beltramino 2013; Hadler et al 2013). Among the species commonly found are those from the genera Megalobulimus (Miller 1878) and Thaumastus (Martens 1860) (Figure 2), both endemic to South America and characteristic of high humidity environments (Colley 2012; Fontenelle et al 2014; Macario et al 2016a).…”

“…Occurring in both past and modern terrestrial environments, the presence of land snails in the archaeological record is not necessarily associated to the archaeological context (Rosa 2006). However, intentional fracture and other anthropic marks increase the probability of previous use as tools or in rituals (Magalhães and Mezzalira 1953; Leme 1975; Solá and Jokl 1978; Mello and Coelho 1989; Simone and Mezzalira 1994; Kneip 2001; Magalhães et al 2001; Brentano et al 2006; Rogge 2006; Teixeira 2006; Gernet and Birckolz 2011; Fontenelle et al 2014). The depth where the shells are retrieved on the site, the abundance of specimens, the site environment, the use of shells as artifacts or cultural material, and burnt marks from the contact with archaeological hearths are criteria used for distinguishing the shells from the occupational context (e.g.…”

Among other zooarchaeological remains, terrestrial snails’ shells from the Thaumastus and Megalobulimus genera are found in some Brazilian shellmounds, presenting a potential substitute for charcoal in radiocarbon dating analyses, as reliable representatives of the atmospheric carbon isotopic ratio. In this paper, we present statistically similar results of both charcoal and land snails samples from the same archaeological contexts in three settlements on the coast of Rio de Janeiro. The Manitiba I shellmound results range from 4.2 to 3.7 ka cal BP (95.4%), contemporary with the Saquarema shellmound, occupied during the period from 4.3 to 3.6 ka cal BP (95.4%). For the Usiminas shellmound, two groups of samples revealed different periods of time for two occupational layers from 2.3 to 2.1 ka cal BP (95.4%) and from 1.6 and 1.3 ka cal BP (95.4%). A model constraining each group of samples to within a single phase has a general agreement of 97% with only two outliers out of 22 dates, yielding minimum individual agreement of 74% and 7% posterior outlier probability for Saquarema shells. These are good examples of sites in which the occupation chronology can be successfully obtained by the radiocarbon dating of land snails.

Megalobulimus dryades sp. nov. is described from the Atlantic Forest in the Vale do Ribeira region, in the states of Paraná and São Paulo, S-SE Brazil, based on morphology. Representatives of the new species with white peristome and glossy periostracum have been misidentified as Megalobulimus gummatus (Hidalgo, 1870) since the 19th Century. The true M. gummatus is revised and redescribed, and its distribution is here restricted to Rio de Janeiro state. Externally, the new species differs from M. gummatus in having distinct protoconch color and sculpture, teleoconch sculpture marked by strong anastomosing rugosities and malleations, and lighter colored white-greyish head-foot. Internally, it presents distinct jaw and radular features, a talon, and a long convoluted penis bearing two flagella. Additional comparisons with other Brazilian congeneric species are also provided.
