| Sumario: | In this work the mollusks found in the Cerro Colorado Cultural Natural Reserve are mentioned in order to have basic information given their ecological and palaeoenvironmental value. Thirteen specific taxa were registered distributed in six families of gastropods (Cochliopidae, Planorbidae, Succineidae, Strophocheilidae, Orthalicidae and Xanthonychidae) and one of bivalves (Corbulidae). The best represented species belong to the genera Bulimulus, Plagiodontes, Spixia, Clessinia and Epiphragmophora. Among the fossils of Holocene age Plagiodontes predominates, while Bulimulus was scarce. Megalobulimus lorentzianus also appears in some older outcrops, for which a new 14C dating gave a calibrated age of circa 6500 years BP, which is relevant given that this species is absent in more recent sediments and today. These results are discussed highlighting the potential of mollusks as environmental and climatic proxies of the Holocene. |
