Abstract

The biochronological age of the small-mammal populations of Los Gargantones 1, 2 and La Celia (upper Miocene, La Celia sub-basin, Murcia, Spain) is re-interpreted. The presence in Los Gargantones of Occitanomys adroveri, Parapodemus barbarae, Parapodemus cf. gaudryi, Huerzelerimys turoliensis, Atlantoxerus cf. adroveri, and Alilepus evidences a correlation to MN12 (~7.5-7. Ma) rather than to MN11 (~9-7.5. Ma), as inferred previously. The assemblage corresponds to that of the more eastern, near-coast sites of Crevillente 8 and 15, situated in the Alicante area. The stratigraphically highest site of La Celia contains Hispanomys adroveri, a species also indicative of MN12. The presence of Castromys cf. littoralis together with an advanced O.. adroveri points to a slightly younger age than that of Los Gargantones, approaching that of MN13 sites. The assemblage best matches that of Crevillente 17. Other species described in this paper are Prolagus crusafonti, Prolagus sp., Parasorex cf. ibericus, Panelimnoecus cf. repenningi, and Blarinella aut Petenyia sp. indet. © 2014 Elsevier Masson SAS.
