The Late Quaternary fossil record of the land snail Austroborus cordillerae (Doering, 1877), an endangered species endemic to the Córdoba province in central Argentina, is treated. In this context, this work provides novel information regarding its ancient distribution area, which would have reached its greatest development prior to the Last Glacial Maximum in the Pampa de Olaen area, and then would have retracted and become locally extinct. Furthermore, the scarce historical records and other recent evidence indicate that towards the end of the Holocene the species had a more reduced distribution compared to its Late Pleistocene distribution. Finally, a set of factors (climatic and anthropic) that could have acted over time causing the retraction, and perhaps local extinctions of this endemic snail, are discussed. |
