[EN] Purpose: A new Iberian Konservat-Lagerstätte discovered in Tresjuncos (Cuenca, Spain) is described and interpreted based on geological and paleontological information. Methods: The samples were studied using conventional mineralogical (powder X-ray diffraction), petrographic (optical and scanning electron microscopy) and geochemical (X-ray energy-dispersive spectrometry) techniques. Results: Based upon geological context, stratigraphy, lithology, sedimentology and origin of the rocks, we describe and interpret the new fossil site as originated in a lacustrine environment. The micromammals found in the Tresjuncos 1 outcrop suggest that the main site is Turolian in age (uppermost Miocene), continental chronological unit MN13. The fossils are preserved in laminates comprising rhythmic, millimeterscale alternations of diatomites and calcareous diatomites. An analysis of the lake paleobiota includes amphibians, crustaceans, insects, plants, and diatoms. The diatoms are dominated by Cyclotella iris. The whole assemblage is indicative of a planktic community developed in somewhat alkaline waters. An extremely well preserved premetamorphic Pelobates (Pelobatidae) tadpole was discovered; it is remarkable because of its gigantic size. Its digestive tract predominantly contains the rare diatom Navicula halionata var directa, likely associated with the shore vegetation in which it presumably lived and fed. The arthropods form a typical lacustrine aquatic assemblage, lacking fish. This assemblage is made up of small filtering crustaceans and of both predator and non-predator insects of diverse sizes. Conclusions: The available evidence on Tresjuncos shows the extraordinary potential for paleontological information that can be expected from this new Konservat-Lagerstätte, which constitutes a significant finding that improves our understanding of continental late Miocene Mediterranean environments. |

Métodos: Las muestras se han estudiado utilizando metodologías convencionales mineralógicas (difracción de rayos X) petrográficas (microscopía óptica y electrónica) y geoquímicas (Espectrometría de energía dispersiva de rayos X). Resultados: Basados en el contexto geológico, estratigrafía, litología, sedimentología y origen de las rocas, describimos e interpretamos la nueva localidad fósil como originada en un ambiente lacustre. Los micromammíferos encontrados en el afloramiento de Tresjuncos 1 sugieren una edad Turoliense (Mioceno superior), unidad cronológica continental MN13. Los fósiles se conservan en laminaciones que comprenden alternancias rítmicas a escala milimétrica de diatomitas y diatomitas calcáreas. Un análisis de la paleobiota del lago incluye anfibios, crustáceos, insectos, plantas y diatomeas. Las diatomeas están dominadas por Cyclotella iris. Todo el conjunto es indicativo de una comunidad planctónica desarrollada en aguas algo alcalinas. Se descubrió un renacuajo de Pelobates (Pelobatidae) pre-metamorfosis muy bien conservado; remarcable debido a su enorme tamaño. Su tracto digestivo contiene predominantemente la rara diatomea Navicula halionata var directa, probablemente asociada con la vegetación de la orilla en la que presumiblemente vivía y se alimentaba. Los artrópodos forman una típica agrupación acuática lacustre, carente de peces. Este conjunto se compone de pequeños crustáceos filtrantes y de insectos predadores y no predadores de diversos tamaños. Conclusiones: La evidencia disponible sobre Tresjuncos muestra el extraordinario potencial de información paleontológica que se puede esperar de esta nueva Konservat-Lagerstätte, que constituye un hallazgo significativo que mejora nuestra comprensión de los ambientes mediterráneos del Mioceno continental.The present research was funded by Spanish Projects CGL2011-27826-CO2-02, CGL2014-54818-P and CGL2015-68333-P (Ministerio de Economía, Industria y Competitividad/FEDER, European Union).Peer ReviewedSpringer NatureMinisterio de Economía y Competitividad (España)European CommissionConsejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]2018201820172018info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Postprintinfo:eu-repo/semantics/acceptedVersionhttp://hdl.handle.net/10261/162222reponame:DIGITAL.CSIC.
