Abstract
La Cueva del Estrecho (Villares del Saz, Cuenca) es un yacimiento arqueo-paleontológico holoceno prácticamente inédito hasta la fecha. Se han estudiado en torno a 970 restos fósiles craneales pertenecientes a 14 taxones de micromamíferos (roedores, lagomorfos, eulipotiflos y quirópteros), procedentes del paquete sedimentario situado en la entrada de la cueva. Una datación (14C-AMS) realizada sobre hueso arroja una antigüedad de 2311-2154 años cal. BP para la asociación de micromamíferos. El estudio tafonómico realizado ha puesto de manifiesto la existencia de una elevada frecuencia de elementos digeridos en la muestra (≥ 70%), que en algunos en algunos casos alcanzan el grado extremo. Además, se han identificado fragmentos de oprolitos adheridos a numerosos restos óseos y dentarios, así como dentición digerida de gazapos. Por todo ello puede afirmarse que el origen de la asociación fue la depredación por parte demamíferos carnívoros, probablemente mustélidos.
The Cave of the Estrecho (Villares del Saz, Cuenca) is a Holocene archaeo-palaeontological site virtually unknown. Over 970 fossil cranial remains of 14 small mammal taxa (rodents, lagomorphs, eulipotyphls, and chiropterans) have been studied. They were collected from the sedimentary package located at the cave entrance. A 14C-AMS performed on a bone gave a date of 2311-2154 years cal. BP for the small mammal assemblage. A taphonomic study shows high frequency of digestion (≥ 70%), achieving extreme digestion degree in the sample. Furthermore, coprolite fragments have been identifi ed adhered to several dental and bone remains, as well as young rabbit digested teeth. Therefore, it can be asserted that the origin of this assemblage was predation by mammal carnivores, probably mustelids.
