Annotated catalogue of the fossil Hygrophila and eupulmonata (Mollusca: Gastropoda) from south America (Cretaceous – Neogene)

Abstract

The South American fossil record of pulmonate gastropods counts with circa 100species from the Cretaceous to the Pliocene. As this knowledge is largely scattered in the literature, we present here a checklist of these fossils, with relevant data about each species’ type locality, stratum and age, and illustrating the type specimens whenever possible. Moreover, some taxonomical problems are highlighted in the hope of garnering attention for future research.
