ABSTRACT

Las Bardenas Reales de Navarra se encuentran en el borde NW de la cuenca terciaria del Ebro. Los sedimentos que podemos encontrar en la mayor parte del área de estudio pertenecen a facies fluvio-palustres de la Formación Tudela. Las localidades fosilíferas estarían incluidas dentro de la Biozona MN2b-MN3 (Biozonas Z-A del Rambliense o Aquitaniense superior-Burdigaliense inferior). En esta área se han encontrado restos fósiles de peces, anfibios, lagartos, anfisbénidos, serpientes, tortugas, cocodrilos, flamencos y los mamíferos que se describen en este trabajo como insectívoros, quirópteros, castores, eomíidos, glíridos, esciúridos, cricétidos, lagomorfos, perisodáctilos y artiodáctilos. The Bardenas Reales of Navarre are located on the NW border of the tertiary Ebro basin. Most of the deposits in the area correspond to fluvio-palustrine facies of the Tudela Formation. The fossiliferous localities probably belong to the Biozones MN2b-MN3 (Biozones Z-A of the lower Ramblian or upper Aquitanian-lower Burdigalian). The fossil remains belong to fish, flamingos and the mammals here described, such as insectivorous, chiropterans, beavers, eomyids, glirids, sciurids, cricetids, lagomorphs, perissodactyls and artiodactyls.

    • "A detailed paleontological survey of the Bardenas Reales has yielded 16 fossil localities, all within palustrine-lacustrine grey marls, distributed throughout the Tudela Formation. This ongoing survey has resulted in the recovery of fossil remains of a wide variety of vertebrates such as reptiles (lizards, amphisbaenians, snakes, turtles, and crocodilians [9], [10]), amphibians (anurans and urodeles [9]), bony fish (Cypriniformes [9]), birds [9], and mammals (insectivores, chiropters rodents, lagomorphs, artiodactyls and perissodactyls [9], [11], [12], [13]). Turtles, crocodiles, amphibians, and fish are autochthonous lacustrine-palustrine faunal components. "

    ABSTRACT: We describe the first occurrence in the fossil record of an aquatic avian twig-nest with five eggs in situ (Early Miocene Tudela Formation, Ebro Basin, Spain). Extensive outcrops of this formation reveal autochthonous avian osteological and oological fossils that represent a single taxon identified as a basal phoenicopterid. Although the eggshell structure is definitively phoenicopterid, the characteristics of both the nest and the eggs are similar to those of modern grebes. These observations allow us to address the origin of the disparities between the sister taxa Podicipedidae and Phoenicopteridae crown clades, and traces the evolution of the nesting and reproductive environments for phoenicopteriforms.

    ABSTRACT: Se estudian y describen 130 restos dentales aislados, un fragmento de maxilar y cuatro fragmentos hemimandibulares de Cainotherium de un nuevo yacimiento, Alameda de Osuna, del Aragoniense medio de la Cuenca de Madrid. El estudio realizado ha permitido determinar la presencia de una especie de Cainotherium de talla pequeña que se cita por primera vez en el registro español, Cainotherium cf. huerzeleri HEIZMANN, 1983 y correlacionar este nivel con los yacimientos del área urbana de Madrid pertenecientes a la MN5 (zona local D). [ABSTRACT] 130 isolated dental remains, one maxilar and four mandibular portions of Cainotherium have been described and studied from Alameda de Osuna, Middle Aragonian of the Madrid Basin. This study has allowed to confirm the presence of one small size Cainotherium specie cited for the first time in the Spanish record, Cainotherium cf. huerzeleri. Alameda de Osuna has been correlated to other Madrid sites belonging to the MN5 (local zone D).

    ABSTRACT: The studies made since the middle of the last century by many authors about the Spanish micromammal faunas of many sites have given rise at present to a good knowledge of the fossil record of the Spanish Neogene. The former synthesis works on Neogene mammals made by López et al. (1987) and Calvo et al. (1993), of the rodents by Sesé (1988) and of the lagomorphs by López (1989) shows the extraordinary fossil richness of the several Spanish geographical areas and basins (Ebro, Tajo, Calatayud-Teruel, Duero, Vallés-Penedés, Levante, Béticas). In the present work it is made a review and update synthesis on the Spanish Neogene (Miocene and Pliocene) rodents (order Rodentia) and lagomorphs (order Lagomorpha), mainly of the peninsula where there are more findings, but also of some findings made in the islands. They have been analysed, mainly from the systematical and biostratigraphical point of view, the faunas of the Neogene sites that have characteristical taxa of their asigned age. The order of the presentation of the analysis is, at a first level, by the stages or mammal ages, giving their most important characteristics, and, at a second level, analysing the most characteristical features of the faunas of each biozone that belong to each stage. These stages are: in the Miocene, the Early Lower Miocene, amblian, Aragonian, Vallesian and Turolian, and, in the Pliocene, the Ruscinian (Alfambrian) and Villanian. Regarding the zones, for the Miocene we follow the local biozonation more used in Spain that comprises the zones named from X to Y and from A to M, correlating them with the MN zones of the Mediterranean Neogene biozonation (Mein, 1975) that is the most used in Europe; and in the Pliocene, we used the MN 14 to MN 17 zones. They have been summarized the dates made in many sites, zones and stages, mainly since the last decade. It is pointed out the biogeographical differentiation between the Ibero-Central and the Ibero-Levant provinces during the most part of the Miocene, and their homogeinity at the end of the Miocene and during the Pliocene with the southern France in the so called Ibero-Occitanian province. It has been also indicated the main paleoenvironmental changes inferred from the micromammal faunal changes, mainly those that have been related with global changes.
