• Resumen

  • Cucú Cave is a small cavity, 30 m long, 1600 m.a.s.l. in the southern slope of Sierra de María (N Almería province, Spain). A sedimentary sequence 9 m thick, including fossils, fills the cave. The lithological sequence is dominated by clast supported detrital sediments without evidence of alluvial transport. These sediments were formed by gelifraction under periglacial conditions. Themicromammal fossil species are of Upper Pleistocene age and the mammal biocenogram also indicates that cold conditions prevailed at the time of deposition, between 140 and 70 ka. Sedimentological and biostratigraphical evidence within the cave indicates, during the Upper Pleistocene, increasing dimensions of the karst cavity previously created by solution. The detritalsequence is covered by a flowstone which evolved during a period of warmer, wetter conditions and provides a minimum U-Th isochron age of 40±7 ka for the timing of periglacial action
