Herpetofauna del Pleistoceno Superior de la cueva de Cobrante

Abstract

[ES]: Se estudian los restos herpetológicos wurmienses del yacimiento del Pleistoceno tardío de la cueva de Cobrante (San Miguel de Aras, Cantabria, España), asociados a niveles correspondientes a diversas fases del Paleolítico Superior. La especie predominante en todos los niveles excavados es Rana temporaria, detectándose también escasos restos de Alytes obstetricans y Bufo bufo. De manera esporádica han aparecido restos aislados de Lacerta sp., serpientes neonatas, y un resto dudoso de Bufo calamita. Entre las anomalías óseas detectadas destacan dos vértebras opistocélicas de Rana temporaria. El material parece proceder de egagrópilas de rapaces distintas a Tyto alba, además de un componente menor de alimentación de mamíferos carnívoros. Dada su disponibilidad como presas, la sedimentación de los restos parece haberse dado entre abril y octubre, probablemente en mayor medida a principios de verano.

[EN]: Herpetological samples from the late Pleistocene wurmian site Cueva de Cobrante (San Miguel de Aras, Cantabria, Spain) are studied. The herpetological remains are associated with different Upper Palaeolithic levels. The predominant species in all excavated levels is Rana temporaria, accompanied by scant remains of Alytes obstetricans and Bufo bufo. Sporadic isolated remains of Lacerta sp., new-born snakes and perhaps Bufo calamita have also been detected. Within the osteological anomalies, two remarkable Rana temporaria opisthocoelous vertebrae have been found. Probably most of the herpetological material comes from raptor pellets different from Tyto alba, plus a minor component derived from carnivore mammal predation. Based on its availability as prey, the sedimentation of these remains seems to have occurred between April and October, probably at a higher rate during the early summer period.
