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.

The micromammal fauna from the Middle Miocene (Middle Aragonian) of La Retama, eastern central Spain, is described. It is a relatively poor rodent fauna composed by ten species only, associated to a highly diverse bat fauna, which includes five genera. The insectivores are represented by two species. This fossil assemblage has been correlated to zone Db (MN 5). The palaeoenvironmental reconstruction based on micromammals indicates open and dry conditions for this locality. Se describen los micromamíferos del Mioceno medio (Aragoniense medio) de La Retama, sector centro-oriental español. La fauna de roedores es relativamente pobre y está compuesta únicamente por diez especies. Sin embargo, cabe destacar la elevada diversidad de los quirópteros, representados por cinco géneros. Se describe también dos taxa de insectívoros. Esta asociación fósil ha sido correlacionada con la zona Db (MN5). La reconstrucción paleoambiental de La Retama inferida a partir de la fauna de micromamíferos corresponde a un ambiente abierto y seco.

Las cuencas de Calatayud-Daroca y Teruel contienen un registro sedimentario y faunístico muy completo del Neógeno continental español. En ellas están definidas las. secciones tipo del Rambliense, Aragoniense, Turoliense y Alfambriense. A su vez, el Vallesiense se encuentra muy bien representado en la parte norte de la Cuenca de Teruel, tanto litoestratigráficamente como por la amplia sucesión de faunas de vertebrados que contiene. En este trabajo se presenta un resumen y puesta al día de la información estratigráfica y sedimentológica disponible sobre las formaciones neógenas de ambas cuencas, incluyendo además datos recientes sobre el límite Aragoniense-Vallesiense en el área de Daroca-Nombrevilla y sobre el registro sedimentario de edad Plioceno en la parte más septentrional de la región de Teruel-Alfambra. Se presenta asimismo un cuadro sintético de las columnas magnetoestratigráficas elaboradas en los últimos años. Con carácter preliminar, se muestran las curvas de evolución paleoclimática (humedad/temperatura) deducibles de las asociaciones de micromamíferos presentes en una densa sucesión de yacimientos que abarcan todo el Mioceno. Las diferencias en los resultados obtenidos sobre la evolución paleoclimática de ambas cuencas son posiblemente debidas a la distinta metodología utilizada en el análisis de las asociaciones faunísticas. Por otra parte, se discuten las faltas de ajuste detectadas, al menos para algunos intervalos temporales, entre los resultados deducibles de este tipo de interpretación paleoclimática y los que se derivan del análisis sedimentológico de los depósitos, The Calatayud-Daroca and Teruel basins (NE Spain) show a very complete sedimentary and faunal record of the Spanish continental Neogene. The stratotypes for the Ramblian, Aragonian, Turolian and Alfambrian stages have been defined in these basins. Moreover, the Vallesian is well recorded especially in the northern Teruel Basin. This paper gives a state-of-the-art summary of the available information generated in the latest years by detailed sedimentological, biostratigraphical and magnetostratigraphical studies of the Neogene deposits of the basins. Recent results concerning the Aragonian-Vallesian boundary in the Daroca-Nombrevilla area are presented. A general integrated scheme of the magnetostratigraphic logs obtained from a large number of stratigraphic sections throughout the region is also included. Preliminary palaeoclimatic evolutionary curves (humidity/temperature) are proposed for the Miocene stratigraphic record of the basins. The curves have been inferred from detailed analysis of the micromarnmal associations found in an extremely dense succession of marnmallocalities. Differences in the palaeoclimatic curves proposed for Calatayud-Daroca and Teruel may be explained by the use of different methodologies. Discrepancies between sedimentological and faunal based interpretations of the palaeoclimatic evolution of some intervals of the Miocene are discussed, España.

A synthesis of the Spanish continental Neogene is presented by designing an integrated correlative chart of the Neo" gen-e "succes"Siuns-ofthe "lberian-PeninsuIa-. -Ninemain-sedimentary-breaks-have-been -distinguished-in-most-of-the "basins. They are considered a valuable criteria for correlation as they occur in similar time intervals from basin to basin. The determined sedimentary breaks occur in the Agenian, Ramblian, Middle Aragonian, Late Aragonian, Late Vallesian, Middle Turolian, Late Turolian, Late Ruscinian-Early Villafranchian, and Villafranchian ages. The larger interior basins (Ebro, Tajo, Duero) show a fairly complete Neogene sedimentary record in which the aboye mentioned sedimentary breaks are usually well recognized. A good correlation may be established from basin to basin. Likewise, there is a fairly good correlation among the Upper Miocene-Pliocene sedimentary record of basins spreading out in Levante and southeastern Spain. However, the correlation is not as c1ear in those basins located within the Iberian and Catalan Coastal Ranges, which usually do not show a similar sedimentary pattern. The comparison between Neogene stratigraphic logs in most of the Spanish continental basins and the pattern of global events from currentIy accepted Cenozoic Cyc1e Charts allows recognition of chronological coincidences, especially with regard to the age of seven major sedimentary ruptures (those developed at about 24.5 Ma, 22 Ma, 16 Ma, 13.5 Ma, 9.5 Ma, 5.5 Ma, 3.3 Ma). Evolutionary sedimentary trends in both offshore Mediterranean areas and inland peripheral zones of the Iberian Peninsula show also striking coincidences regarding the chronology of major sedimentary breaks observed in continental successions. Paleoc1imatic curves for the Spanish continental Neogene display four relative temperature peaks indicative of warm c1imatic conditions (Late Agenian, Early-Middle Aragonian, Vallesian-Turolian, and Late Villafranchian) as well as five relatively dry peri, Se presenta en este trabajo una síntesis del Neógeno continental español mediante la elaboración de un esquema de correlación general de las sucesiones neógenas en la Península Ibérica. Se reconocen nueve rupturas o discontinuidades mayores dentro del registro sedimentario de un total de 16 áreas que cubren la mayor parte de las cuencas continentales terciarias de la Península. Las rupturas, denominadas de acuerdo con su posición cronológica, son las siguientes: Ageniense, Rambliense, Aragoniense medio, Aragoniense superior, Vallesiense superior, Turoliense medio, Turoliense superior, Rusciniense superior-Villafranquiense inferior y Villafranquiense. Las grandes cuencas interiores (Ebro, Tajo, Duero) presentan un registro muy completo de las sucesiones neógenas y de las rupturas arriba señaladas, las cuales tienen buena correlación de una cuenca a otra. De igual modo, existe una correlación notable entre los registros sedimentarios del Mioceno superior-Plioceno de las cuencas de Levante y el Sudeste. Sin embargo, la correlación es menor con las cuencas situadas en la Cadena Ibérica y la Cadena Costero Catalana. La comparación entre el registro sedimentario Neógeno obtenido en gran parte de las cuencas continentales españolas y la secuencia de eventos globales a partir de los cuadros de ciclicidad para el Cenozoico actualmente aceptados permite reconocer coincidencias cronológicas entre ambos, especialmente en lo que se refiere a siete de las rupturas sedimentarias mayores (las definidas a 24.5 Ma, 22 Ma, 16 Ma, 13.5 Ma, 9.5 Ma, 5.5. Ma, 3.3 Ma). Las tendencias en la evolución sedimentaria de las sucesiones Neógenas, tanto en áreas del "offshore" Mediterráneo como en zonas periféricas de la Península Ibérica, muestran igualmente notables coincidencias en lo que se refiere a la cronología de rupturas sedimentarias mayores observadas en sucesiones continentales.

In this paper the micromammals from three localities in the Oligocene/Miocene boundary interval and the Lower Miocene of the Ebro Basin in the Province of Huesca (northern Spain) are described. Twenty-five species are recognized, two of which are new (Quercomys daamsi de Visser and Peridyromys turbatus Alvarez Sierra et al.; Gliridae). One new subspecies belonging to the Ochotonidae (Prolagus vasconiensis fortis López Martínez & Sesé) is described. The biostratigraphy, palaeoecological implications and palaeobiogeography are discussed.

The paleoecological analysis of Neogene rodent faunas in the Calatayud-Teruel Basin leads to the recognition of three realtively cool, and two relatively warm periods. The humidity curve reveals four wet and four dry periods. The results agree remarkably well with temperature and humidity curves obtained from other geological disciplines.

The Lower Pleistocene succession, the pollen and some smaller mammals from the upper part of the boring Brielle (SW Netherlands) are described. The correlation between the Eburonian Glacial Stage and the mammal-based subdivision of the Biharian Stage is discussed.

By means of modernized sieving techniques 110 m3 of matrix from a gully filling in the Tegelen Clay were sieved. This yielded a good collection of small mammals, which clarifies the stratigraphic position of the Tiglian, a collection of other vertebrates, a small collection of mollusks, and a vast amount of plant material. A good collection of mollusks was made through classical collecting techniques. The faunal lists in this paper constitute a considerable enlargement of the known Tegelen fauna. Collecting is continuing, and further additions to the fauna may be expected.
