    Description: The Cerro de los Batallones (Los Batallones Butte) is located in the central-northern area of the Madrid Basin, central Spain. Nine vertebrates localities containing a large variety of mammals of Upper Vallesian Age (Late Miocene) have been found associated with the sediments forming the butte. From bottom to top, these sediments consist of magnesian lutite beds (Unit I), paleosols formed of sepiolite and opal (Unit II), and siliclastic, marlstone and carbonate beds (Unit III). The set of ERT profiles developed in Los Batallones Butte have demonstrate that electrical imaging techniques are an estimable tool for the characterization and prospecting of fossil sites developed in fine-grained siliciclastic sequences. These localities contain an exceptionally rich, varied and well-preserved vertebrate fauna together with invertebrate and plant fossils. Carnivore species are strikingly well represented at Batallones 1 and 3, and large herbivore species, such as mastodons, rhinoceros and giraffes, at Batallones 2, 4, 5 and 10. The taphonomical studies, together with the morphological features shown by the sedimentary fills of the mammal localities, permit an overall interpretation of these deposits as vertebrate traps. The study of these localities should offer a significant contribution to our understanding of the formation pattern of trap-like paleontological sites - which so far have been typically reported in karstic-type systems -, as well as an important source of paleobiological information about numerous vertebrate groups.

    Description: La República de Panamá posee un territorio marítimo con una superficie de 319.823.9 km2 versus una superficie total emergida de 75.517 km2. El país posee una importante longitud de sus costas, que comprenden un total de 2.988,3 kilómetros. De éstos, 1.700,6 km corresponden al litoral Pacífico y 1.287,7 km al litoral Caribe. La superficie continental del Istmo de Panamá se caracteriza por tierras bajas y colinas menores de 700 msnm, las cuales comprenden un 70 % del total. El Istmo con su forma característica de una “S” acostada se encuentra separado en dos Vertientes, Pacífico y Caribe, por la formación longitudinal de la denominada Cordillera Central, ubicada casi a todo lo largo del istmo y ella constituye el parte aguas y determina el clima en ambas vertientes. La Cordillera Central forma la región denominada las tierras altas, que comprenden la Cordillera Central, la Cadena Occidental, el Macizo del Canajagua y las Serranías de San Blas y Darién. Siendo el Volcán Barú con 3.475 msnm el punto más alto del país (Contraloría General de la República, 2005 y 2006).
