Revision and new data of the ammonite family Pseudotissotiidae in the Iberian Trough, Spain
The ammonites assigned to the family Pseudotissotiidae of the Wiedmann (Tübingen,Germany) and Goy, Carretero and Meléndez (Madrid, Spain) collections obtained from the Iberian Trough have been revised. New, mainly lower Turonian, specimens of the species Pseudotissotia sp., Choffaticeras (Choffaticeras) quaasi (Peron, 1904), C. (C.) pavillieri (Pervinquière, 1907), C. (C.) segne (Solger, 1903), C. (C.) sinaiticum (Douvillé, 1928), C. (Leoniceras) luciae (Pervinquiére, 1907), C. (L.) barjonai (Choffat, 1898), Wrightoceras llarenai (Karrenberg, 1935), W. munieri (Pervinquière, 1907), W. submunieri Wiedmann, 1975b, and Donenriquoceras forbesiceratiforme Wiedmann, 1960, have been also presented. In addition, we designate and refigure the lectotype of Pseudotissotia (Leoniceras) alaouitense Basse, 1937, and refigure the lectotype of P. barjonai Choffat, 1898. Studies on the morphologies and the geographical and temporal distributions of all of these species have led to the identification of several phylogenetic relationships between them, and to distinguish four main phases in the evolution of the family, characterized by the successive dominance of Choffaticeras (Choffaticeras), Choffaticeras (Leoniceras), Donenriquoceras and Wrightoceras with Donenriquoceras
The ammonite genera Fagesia and Neoptychites (family Vascoceratidae) in the Iberian Trough, Spain
The ammonites assigned to the genera Fagesia Pervinquière, and Neoptychites Kossmat, of the Wiedmann (Tübingen, Germany) and Goy, Carretero and Meléndez (Madrid, Spain) collections obtained from the Iberian Trough have been revised. New mainly lower Turonian specimens of the species Fagesia catinus (Mantell), F. tevesthensis (Peron), F. rudra (Stoliczka), F. superstes (Kossmat), F. pachydiscoides Spath, and Neoptychites cephalotus (Courtiller) have also been presented. In addition we have described one new species: F. mortzestus. Studies of the morphologies and the geographical and stratigraphical distributions of all these species have led to the identification of several phylogenetic relationships between them, and to distinguishing one main phase in the evolution of the family Vascoceratidae Douvillé, characterised by the dominance of Fagesia with Neoptychites
Revision of the terminology applied to the post-Triassic nautiloids and ammonoids in Spanish
Tras revisar la terminología aplicada a los nautiloideos y ammonoideos postriásicos en español se han identificado más de 350 vocablos, que han sido analizados y presentados en orden alfabético con sus respectivas etimologías, definiciones, comentarios y equivalentes en inglés. Como resultado de este trabajo, se ha creado un glosario, fundamentalmente práctico, al que pueden recurrir distintos especialistas para redactar de una forma más precisa y ordenada las descripciones sobre los citados cefalópodos o interpretar con mayor facilidad los trabajos de otros autores en lengua tanto española como inglesa.After the revision of the terminology applied to the post-Triassic nautiloids and ammonoids in Spanish more than 350
words have been identified, which have been analysed and presented in alphabetical order with their respective etymologies, definitions, comments and English equivalents. As result of this work, a glossary, fundamentally practical, has been created as a tool for different specialists to write more precise and methodically the descriptions of these cephalopods or to interpret more easily the works of other authors in Spanish or in English languages.Depto. de Geodinámica, Estratigrafía y PaleontologíaFac. de Ciencias GeológicasTRUEMadrid (Comunidad Autónoma).

Didáctica e possibilidades de divulgação do sítio paleontológico do Cretácico da Figueira da Foz (Portugal)
ABSTRACT: The sedimentary exposures and the palaeontological site of Figueira da Foz (Portugal) are located near the coastal town of the same name, in front of the Mondego river estuary, where a set of mid
Cenomanian to lower Turonian (Upper Cretaceous) marine beds of the West Portuguese Carbonate Platform are recorded by the Costa d’Arnes Formation. The 65 meters thick of the stratigraphic succession holds
several fossiliferous units with diverse ammonite species and other abundant benthic invertebrates with Tethyan affinities, quite accessible for outreach activities. This context allows to combine indoor and out-of school learning strategies along with diverse didactic methodologies, aiming to reach a meaningful learning by carrying out didactic activities at the site and other contemporary outcrops such as Tamajón (Spain). These
initiatives will incentive positive Geoconservation attitudes towards Natural Heritage, by means of outreach and Geotouristic events at the Figueira da Foz site, and related museums and interpretation centres.RESUMO: Os afloramentos e o sítio paleontológico da Figueira da Foz (Portugal) localizam-se junto da cidade com o mesmo nome, em frente ao estuário do rio Mondego. Correspondem a uma sucessão de estratos
marinhos do Cenomaniano médio a Turoniano inferior (Cretácico Superior) da Plataforma Carbonatada Ocidental Portuguesa, pertencente à Formação de Costa d’Arnes. Os 65 metros de espessura da sucessão
estratigráfica contêm várias unidades fossilíferas com amonites e abundantes invertebrados bentónicos com afinidades tetisianas, bastante acessíveis para actividades de divulgação. Este contexto permite combinar
estratégias de aprendizagem dentro e fora da escola, e diversas metodologias didácticas, para se alcançar uma aprendizagem significativa através da realização de actividades didácticas no geossítio e em outros
afloramentos contemporâneos, como em Tamajón (Espanha). Estas iniciativas poderão motivar atitudes positivas de Geoconservação do Património Natural, se incluídas em eventos geoturísticos e de divulgação
no geossítio da Figueira da Foz, em museus e em centros de interpretação.info:eu-repo/semantics/publishedVersio
The biota of the Upper Cretaceous site of Lo Hueco (Cuenca, Spain)
The Late Cretaceous (Campanian-Maastrichtian) fossil site of Lo Hueco was recently discovered close to the village of Fuentes (Cuenca, Spain) during the cutting of a little hill for installation of the railway of the Madrid-Levante high-speed train. To date, it has yielded a rich collection of well-preserved Cretaceous macrofossils, including plants, invertebrates, and vertebrates. The recovered fossil assemblage is mainly composed of plants, molluscs (bivalves and gastropods), actinopterygians and teleosteans fishes, amphibians, panpleurodiran (bothremydids) and pancryptodiran turtles, squamate lizards, eusuchian crocodyliforms, rhabdodontid ornithopods, theropods (mainly dromaeosaurids), and titanosaur sauropods. This assemblage was deposited in a near-coast continental muddy floodplain crossed by distri-butary sandy channels, exposed intermittently to brackish or marine and freshwater flooding as well as to partial or total desiccation events
The geological travels of Juan Vilanova y Piera across Europe
Juan Vilanova y Piera, personaje poliédrico, fue uno de los principales protagonistas de la vida científica del siglo XIX, llevando a cabo infinidad de proyectos. Destacables son sus viajes geológicos por Europa, que no sólo le permitieron mantener estrechas colaboraciones con especialistas de distintas disciplinas, sino que le dieron la posibilidad de recopilar una importantísima colección de muestras litológicas, paleontológicas y arqueológicas, mayoritariamente destinadas al Museo Nacional de Ciencias Naturales (Madrid, España). Vilanova visitó, entre otras, diversas regiones de Francia, Suiza, Italia, Austria, Alemania, Chequia y Hungría, recopilando abundante material de interés científico, lo que le resultará muy útil para sus posteriores investigaciones en España. Durante sus excursiones geológicas, en muchas ocasiones estuvo acompañado y asesorado por reconocidos científicos del lugar, gracias a las recomendaciones de personajes ilustres, como Mariano de la Paz Graells, manteniendo con éste una intensa correspondencia. En el campo de la geología en general y la paleontología en particular es de subrayar su estrecho trato con Alcide d’Orbigny, Claude-Émile Bayle, Jules Thurmann y Amanz Gressly, entre otros y, como resultado, la obtención y difusión de datos paleontológicos de gran interés que abrieron el debate científico sobre el darwinismo en España.Juan Vilanova y Piera was a multifaceted person, and one of the main protagonists of the scientific life in the
19th century. At that time, he carried out numerous projects in different disciplines. Especially remarkable are his
geological trips across Europe that not only allowed him to maintain close partnerships with scientists from different
disciplines, but also gave him the possibility to collect an extremely important collection of lithological, paleontological
and archaeological samples, mainly intended for the Museo Nacional de Ciencias Naturales (Madrid, Spain). Vilanova
visited, among others, different regions of France, Switzerland, Italy, Austria, Germany, Czech Republic and Hungary,
collecting abundant material of scientific interest, which was very useful for his later research in Spain. During his
geological excursions, on many times he was accompanied and advised by renowned local scientists, thanks to the
recommendations of famous people, such as Mariano de la Paz Graells, keeping with him an intense correspondence
during his stay outside Spain. In the field of the geology in general and the paleontology in particular it must be
emphasized his close personal contact with Alcide d'Orbigny, Claude-Emile Bayle, Jules Thurmann and Amanz
Gressly, among others and, as a result, the obtaining of the collection and the dissemination of paleontological data of
great interest to open the scientific discussion about Darwinism in Spain.Depto. de Geodinámica, Estratigrafía y PaleontologíaFac. de Ciencias GeológicasTRUEMinisterio de Economía y Competitividad (MINECO)pu

New palaeontological data on the Upper Cretaceous of Pálmaces de Jadraque and Veguillas (Guadalajara, Spain)
Con el fin de actualizar y ampliar los trabajos paleontológicos previos sobre el Cretácico Superior del Norte de Guadalajara, se han estudiado dos columnas estratigráficas en las localidades de Pálmaces de Jadraque y Veguillas. Las facies analizadas representan la transgresión y el comienzo de la regresión del Cenomaniense superior-Turoniense inferior. El material paleontológico recogido se ha estudiado sistemáticamente, identificándose: Seis taxones de bivalvos, dos taxones de gasterópodos, dos taxones de cefalópodos y dos taxones de equinoideos.In order to update and expand the previous palaeontological studies about the Upper Cretaceous of the North of Guadalajara two stratigraphic sections have been studied near the villages of Pálmaces de Jadraque and Veguillas
(Figs. 1, 2). Studied facies correspond to three different formations (Arenas, arcillas y calizas de Santa María de
las Hoyas, Margas de Picofrentes and Dolomías de la Ciudad Encantada) that represent the transgression and the beginning of the regression of the upper Cenomanian-lower Turonian. The collected palaeontological material has
been studied systematically and thirteen taxa have been identified: six bivalves, two gastropods, two cephalopods and two echinoids. Besides, two different biotic associations have been identified. The first one corresponds to a relative shallow environment with a fauna of epifaunal bivalves and gastropods that are located in the Santa María de las Hoyas Formation. The second represents a deeper environment with infaunal bivalves, gastropods, ammonoids and echinoids, and is located in the Picofrentes Formation.Depto. de Geodinámica, Estratigrafía y PaleontologíaFac. de Ciencias GeológicasTRUEMinisterio de Ciencia e Innovación (MICINN)pu
