Abstract

The remains of a macro carnivore have been collected from the Benis Cave (-220m), Cieza, Murcia. The preliminary dental analysis applied on the premolar (P4) and the molar teeth (M1), suggests that it was a “Lynx pardinus spelaeus”. We have used the calibrated technique of racemisation to obtain a date of 64.4 ± 17.6 ka (Upper Pleistocene). Despite the high atmospheric temperature into the cave (24ºC) and the high-values of dioxide of carbon (600 ppm), the absence of daylight, constant temperature (no seasonal temperature changes) and absence of carbonatic precipitation on the bones surface, yield a suitable conditions to establish the age of the paleontological remains. Furthermore, we have applied X-ray to the canines to establish the age of the lynx (6-8 yrs). All data obtained suggest that a possible ceiling collapse of the cave entrance could be the cause of the death.
