Implicancias paleoclimáticas y biogeográficas de moluscos terrestres y dulceacuícolas del holoceno tardío en isla mocha, Provincia de Arauco, Chile

Abstract

Archaeological excavations on Mocha Island yielded stratigraphic evidence for terrestrial (Endodontidae), and freshwater (Sphaeridae, Amnicolidae, Succineidae) mollusks. It suggests wet conditions by the end of the Late Holocene (post-900 BP), what coincide with previous palinological studies. These mollusks provide relevant information to discuss the micromollusks colonization process in this island.
