In many aspects Pomacea canaliculata (Lamarck, 1822) is the best known native snail from Argentina, a fact that has been enhanced since its establishment as a serious rice plague in Asian rice fields (Estebenet et al., 2006). Notwithstanding, from a paleontological viewpoint, the knowledge of this species is far from being sound and integrated. The aims of our paper are to review the fossil record of Pomacea Perry, 1810 in Argentina, to analyze the preservation of its remains and their usefulness as paleoenvironmental indicators, and to highlight their contribution to the understanding of its present distribution.
