Micromammals (rodents and insectivores) from the early Late Pleistocene cave site of Bois Roche (Charente, France): Systematics and paleoclimatology

Abstract

Résumé: Nous présentons l’étude des rongeurs et insectivores du gisement du début du Pléistocène supérieur de Bois Roche (Charente, France) à partir du matériel provenant de la campagne de fouille de 1995. Le gisement est situé dans une petite grotte à plafond bas, utilisée par des hyènes comme repère. Il renferme un grand ensemble d’herbivores (bovidés et suidés principalement), avec une mineure représentation de mammifères de taille moyenne (cervidés), plusieurs microvertébrés, abondants coprolithes et dents de lait d’hyènes, et quelques artefacts lithiques (Paléolithique moyen) introduits dans la grotte par gravité et ruissellement. La faune de rongeurs est composée de Eliomys quercinus cf. quercinus, Apodemus sp., Microtus gregalis, Microtus oeconomus, Arvicola terrestris et Dicrostonyx torquatus. Les insectivores sont représentés par Neomys cf. fodiens. L’espèce plus abondante est M. gregalis qui constitue 93,7 % du NMI total. La faune des micromammifères suggère un paysage ouvert, avec végétation principalement de steppe ou toundra, aires avec étangs et végétation plus humide et quelques zones avec des arbres. L’association des petits mammifères de Bois Roche est caractéristique d’un climat sec et froid ou très froid.

Resumen: Presentamos el estudio de los roedores e insectívoros del yacimiento del comienzo del Pleistoceno Superior de Bois Roche (Charente, Francia), procedentes de la campaña de excavación de 1995. El yacimiento está situado en una pequeña cueva de techo bajo, utilizada por las hienas como madriguera. Contiene gran abundancia de herbívoros (principalmente bóvidos y équidos) y una menor representación de mamíferos de talla media (cérvidos), muchos microvertebrados, abundantes coprolitos y dentición decidua de hienas, y algunos instrumentos líticos (Paleolítico Medio) introducidos en la cueva por gravedad y por el lavado de las pendientes. La fauna de roedores está formada por Eliomys quercinus cf. quercinus, Apodemus sp., Microtus gregalis, Microtus oeconomus, Arvicola terrestris y Dicrostonyx torquatus. Los insectívoros está representados por Neomys cf. fodiens. Microtus gregalis es la especie más abundante constituyendo el 93,7% del total de NMI. La fauna de micromamíferos sugiere un paisaje abierto con cierta vegetación esteparia o de tundra, con áreas de agua y vegetación más húmeda y algunas zonas arboladas. La asociación de micromamíferos de Bois Roche es característica de un clima seco y frío o muy frío.

Abstract: We present the study of rodents and insectivores from the 1995 season of excavation at the early Late Pleistocene site of Bois Roche (Charente, France). The site is a small cave with a low ceiling, used as a den by hyenas. It contains a large herbivore assemblage (mainly bovids and equids) with a smaller representation of medium-size taxa (cervids), many microvertebrates, abundant coprolites and deciduous hyena teeth, and a few lithic artifacts (Middle Paleolithic) introduced into the cave by gravity and slope wash. The rodent fauna consists of Eliomys quercinus cf. quercinus, Apodemus sp., Microtus gregalis, Microtus oeconomus, Arvicola terrestris and Dicrostonyx torquatus. Insectivores are represented by Neomys cf. fodiens. The most common species is M. gregalis which forms 93.7% of the total MNI. The micromammal fauna suggests an open landscape, with some vegetation mainly of the steppe or tundra type, with areas of water and more wet vegetation and some areas with trees. The micromammal association of Bois Roche is characteristic of a cold or very cold dry climate.
