Early Jurassic (Sinemurian) gastropods from the Lusitanian Basin (west of Portugal)

The Sinemurian gastropod specimens herein studied come from two sources: from museum collections and from samplings in field. The study of the Sinemurian gastropod specimens housed in the collections of the Museu Geológico (Laboratório Nacional de Energia e Geologia), Museu Nacional de História Natural e da Ciência (University of Lisbon), Museu da Ciência (University of Coimbra) and of the Museu de História Natural e da Ciência (University of Porto), has allowed the systematic and taxonomical update of this material. These specimens come mostly from Sinemurian outcrops in S. Pedro de Moel area and Coimbra region, and were collected by Paul Choffat and collaborators in the geological field works in relation to the cartography of the Portuguese Geological Map in 1887 and 1903. The review of these collections permitted to recognise original material that was used to describe several characteristic species of the Lusitanian Basin, namely Scurriopsis (Scurriopsis) schmidti, Cryptaenia sp., Nerinella ficalhoi, and Boehmiola exilis. The study of the specimens sampled in field has allowed confirming the origin and stratigraphic position of those specimens collected by Choffat. This sampling was carried out in materials of Coimbra and Água de Madeiros formations (Obtusum and Oxynotum chronozones) cropping out in S. Pedro de Moel, Praia Polvoeira, and Praia Pedra do Ouro. A total of 386 specimens have been studied, 266 have been assigned to 14 taxa of 14 families, 13 genera and 8 species. Most of these taxa belong to the subclass Caenogastropoda (61.31% of the specimens), to the order Allogastropoda (30.66%), and the superfamilies Campaniloidea (28.83%) and Nerinoidea (20.8%). The most common species are endemic of the Lusitanian Basin, namely Pseudomelania costae Pictet & Campiche, 1862 and Oonia casta Böhm, 1901. Other species are known in Germany, Luxembourg and Austria basins

The Sinemurian (Lower Jurassic) Gastropod Collection from the «Comissões Geológicas» of Portugal

The «Comissões Geológicas» of Portugal evolved from 1857 to 1918. Paul Choffat, who specialised in the study of the Mesozoic stratigraphy and palaeontology, was one of its members and an active collaborator. He and his collectors compiled a reference extensive collection of Sinemurian gastropods, mainly collected from the S. Pedro de Moel and Coimbra areas. A total of 395 specimens are currently recognisable; the remaining ones were lost in fires or relocations. The major part of the present collection (74.68%) is housed in the Museu Geológico (Lisbon), where the labels are preserved and where the type and figured specimens in classical works are kept; the remaining specimens can be found in three other institutions, where they mostly resulted from offers: the Museu Nacional de História Natural e da Ciência – Universidade de Lisboa, the Museu da Ciência da Universidade de Coimbra, and the Museu de História Natural e da Ciência da Universidade do Porto. These collections have unique taxonomical and stratigraphical information about outcrops no longer accessible. The creation of a virtual support not only makes the universal access easier, but also contributes to a better preservation of this invaluable material

Organizational aspects and formative value of the implementation of a palaeontological Escape Room by students of the Master of Advanced Palaeontology (UCM)

Este estudio indaga si el estudiantado de un máster está preparado para organizar una actividad ocio-formativa dirigida a público general, y evalúa la propia actividad como método divulgativo de la paleontología. Para ello se han analizado los resultados de la implementación de un Escape Room paleontológico, organizada por un grupo de estudiantes del Máster Interuniversitario en Paleontología Avanzada de la Universidad Complutense de Madrid durante la XVIII Semana de la Ciencia de Madrid, y se presentan las fases y el desarrollo de dicho Escape Room, que justifican su interés educativo. Los estudiantes organizadores manifestaron un alto grado de compromiso y satisfacción alegando como motivación a participar su interés por la ciencia y por aprender a realizar una divulgación científica eficaz. Esta actividad ha supuesto para el estudiantado organizador una aplicación de lo aprendido en el aula y les ha permitido mejorar competencias que les serán de utilidad a largo plazo. La inmensa mayoría de los asistentes valoraron positivamente la actividad y consideraron que habían aprendido con ella. Conocer como sociedad el pasado de la Tierra, así como nuestros propios orígenes, es la llave para inferir nuestro futuro y, al menos en parte, valorar, preservar y proteger el patrimonio natural que nos rodea.This study aims to answer the question of whether the students of a master’s degree are qualified to organise a leisure-educational activity aimed at high school students and the general public, and assesses whether said activity works as an educational tool for palaeontology outreach. For this, the results obtained from a palaeontology-themed escape room implemented by a group of students of the master’s degree in Advanced Palaeontology at the Complutense University of Madrid during the XVIII Week of Science in Madrid have been analysed and the phases and development of the escape room are presented. Contributing students expressed a high degree of commitment and satisfaction, claiming as the main incentive to participate their interest in science and learning to achieve effective scientific dissemination. This activity has meant for the organizing students an application of what they have learned in the classroom and has allowed them to improve skills that will be useful in the long term. The evaluation of the experience by the attendees was also very positive. The great majority recommended the activity and considered that they had learned from it. Knowing as a society the past of the Earth and life, as well as our own origins, is the key to infer our future and, at least in part, to value the natural heritage that surrounds us and therefore to preserve and protect it.Depto. de Geodinámica, Estratigrafía y PaleontologíaFac. de Ciencias GeológicasTRUEFundación madri+dUniversidad Complutense de Madridpu

Estudio sistemático de los gasterópodos del Sinemuriense de la Cuenca Lusitánica

El objetivo principal de este Trabajo Fin de Máster es caracterizar la fauna de gasterópodos del Sinemuriense Superior de la Cuenca Lusitánica con el fin de ampliar el conocimiento que se tiene sobre ella ya que, hasta el momento, las investigaciones geológicas y las paleontológicas han estado focalizadas en estudios sobre ammonoideos, braquiópodos y bivalvos. Es la primera vez que se realiza un estudio sistemático de fósiles de la Clase Gastropoda.Financiado parcialmente por el Proyecto CGL2015-66604-R del Ministerio de Economía y CompetitividadDepto. de Geodinámica, Estratigrafía y PaleontologíaFac. de Ciencias GeológicasTRUEsubmitte

Ammonoids of the Oxynotum Zone and Raricostatum Zone (Densinodulum Subzone) of Sinemurian, Lower Jurassic, in the Asturian and Lusitanian basins

This research is focused on the ammonoids of Oxynotum Zone and Raricostatum Zone (Densinodulum Subzone) from Asturian (Spain) and Lusitanian (Portugal) basins. They come from expanded sections from where 216 specimens have been collected. These have been classified in eight genera and 15 species that belong to families Echioceratidae, Oxynoticeratidae and Eoderoceratidae. Most of the ammonoids are typical of the Northwest European Province. Echioceratidae is the most frequent in the Asturian Basin, whereas Oxynoticeratidae is the predominant in the Lusitanian Basin. Eoderoceratidae specimens are scarcer, and they are registered only between the middle part of Oxynotum Subzone and the lower part of Densinodulum Subzone. A new species is proposed for the upper part of Oxynotum Subzone of the Lusitanian Basin, Plesechioceras rochai sp. nov., which is relatively frequent. As well, also in Portugal, Cheltonia sp. is registered in Densinodulum Subzone, which is a form different from Cheltonia accipitris. This provides new evidence to support the hypothesis of the relation micro-macroconch between the genera Oxynoticeras (M) and Cheltonia (m). Remarkable differences in the studied area are the presence of Paroxynoticeras salisburgense and Plesechioceras cf. delicatum in the Asturias Basin, and Crucilobiceras densinodulum, associated to Oxynoticeras lymense, in the Lusitanian Basin
