El “retorno” del lirón enano a la Península Ibérica
Nuestro aragosaurero, Juan Rofes (CNRS/MNHN Paris), ha colaborado en un artículo liderado por Naroa García Ibaibarriaga (EHU-UPV) en el que se dan a conocer los primeros restos peninsulares de época cuaternaria del lirón enano (Muscardinus avellanarius), hallados en el yacimiento vasco de Lezetxiki (Arrasate, Gipuzkoa), fuente de continuos descubrimientos. El artículo ha sido publicado en la prestigiosa revista Quaternary Science Reviews, una de las más importantes de temática cuaternaria del mundo.
La importancia de este hallazgo es doble. Por un lado estamos frente a los primeros restos de esta especie en la Península Ibérica de cronología cuaternaria. Y es que, aunque los restos más antiguos de este género provienen de yacimientos peninsulares del Mioceno, la ausencia de registro indica que desapareció de estas tierras durante el Plioceno Inferior. Además, este hallazgo implica la ampliación de la distribución geográfica del lirón enano, al constituir los dientes hallados en Lezetxiki el registro más al suroeste del género en el continente euroasiático.
La información paleoecológica aportada por esta especie confirma las conclusiones del análisis del conjunto microfaunístico identificado en los mismos niveles. Es decir, que el clima de esa época era parecido al actual, de modo que el entorno de la cueva estaría dominado por un paisaje boscoso.
El lirón enano actualmente habita en casi toda Europa, desde el este de Francia hasta Rusia. Habitualmente su presencia está ligada a la existencia de avellanos (no en vano, en inglés se le conoce como Hazel dormouse), aunque puede hallarse en diversos tipos de bosque. Debido a su pequeño tamaño y su rara costumbre de descender de los árboles, es una especie difícil de cazar para las aves rapaces, por lo que su presencia en los depósitos suele ser exigua.
Lezetxiki es conocido internacionalmente por ser uno de los pocos yacimientos de la Cornisa Cantábrica en el que se han localizado restos humanos, tanto de neandertales como de Homo heidelbergensis. Además, no es la primera vez que esta gruta depara sorpresas paleontológicas. Durante las últimas campañas de excavaciones dirigidas por el profesor de la Universidad del País Vasco Álvaro Arrizabalaga, su equipo de investigación ha recuperado también un fragmento de la mandíbula inferior de uno de los últimos ejemplares europeos de macaco (Macaca sylvanus), así como los primeros restos del ratón de los abedules (Sicista betulina) localizados en la Península Ibérica.

from construction and development sites in the county. It prepares,
curates and databases these objects, and uses them in research,
public engagement (events, exhibits, lectures), education (K-12,
college, graduate and post-doctoral), and university research and
teaching. The collections, estimated at 6 million specimens collected
over the last 50 years, document the history of life in OC for the past
180 million years, including human occupation from at least 10,000 to 50
years ago. The fossil collection is rich in invertebrates,
microfossils and plants from the Jurassic to the Recent, and in Neogene
marine mammals, including cetaceans, pinnipeds (walruses, sea lions and
seals), desmostylians, and sea cows. Eocene, Oligocene and
Pleistocene terrestrial mammals are also abundant. Dinosaurs come in

Quiropteros y neandertales en Aguión, Zaragoza.
En este trabajo liderado por la aragosaurera Julia Galán y recientemente publicado en la revista de impacto Comptes Rendus Palevol se analizan los restos de murciélagos o quirópteros (Chiroptera, Mammalia) fósiles identificados en el yacimiento aragonés de la cueva AGP-7 (Aguilón P7), localizado en el municipio de Aguilón (Zaragoza).
Se trata de uno de los raros yacimientos paleontológicos situados en la margen sur del Río Ebro con evidencias de presencia neandertal. El relleno sedimentario de la cavidad, del que se han recuperado tanto los restos de industria lítica que evidencian la presencia de nuestros parientes humanos así como restos fósiles de fauna entre los que se cuentan los murciélagos, fue depositado durante la primera mitad del periodo MIS3 (Marine Isotopical Stadium 3) en el Pleistoceno Superior. Este es un momento de la prehistoria en el que los neandertales de la Península aún no habían entrado en contacto con los humanos anatómicamente modernos y que se caracterizó por una gran inestabilidad climática y una rápida sucesión (en términos de tiempo geológico) de periodos cálidos y fríos.
El estudio de los yacimientos cuaternarios de las cavidades del Cerro del Pezón de Aguilón lo inició el grupo de investigación Aragosaurus a partir del año 2005, cuando la presencia de restos de fauna fósil en estas cavidades fue reportada por el investigador y colega de esta casa Dr. Samuel Zamora. Se trata de un proyecto para el cual se contó con el apoyo del CEA (Centro de Espeleología de Aragón) y para el que a raíz de la aparición de vestigios de ocupación neandertal se formó un equipo multidisciplinar que cuenta con miembros del Centro de investigación (UCM-ISCIII) sobre Evolución y Comportamiento Humanos así como del Área de Prehistoria de la Universidad de Zaragoza.
Los quirópteros son una fuente de información paleoambiental valiosa e independiente en los yacimientos paleontológicos del Cuaternario porque las acumulaciones de fósiles de estos animales no están necesariamente producidas por los mismos mecanismos que las de otros mamíferos de pequeño tamaño (como los roedores y los insectívoros) que aparecen en los mismos yacimientos y que tradicionalmente se han venido empleando en las reconstrucciones de tipo paleoclimático y paleoecológico. El motivo es que estos pequeños mamíferos alados presentan unas condiciones biológicas únicas, como la capacidad de vuelo activo, hábitos de vida nocturnos, hibernación, una gran longevidad y estrategia reproductiva conservadora.
El resultado es que, si bien el número de restos de quirópteros recuperados no es muy abundante en AGP-7, sí que se trata de una asociación fósil sorprendentemente diversa (con muchos taxones distintos representados) si se compara con otros yacimientos ibéricos de edad similar. Se han identificaron nueve taxones de murciélagos: Rhinolophus ferumequinum, Rhinolophus hipposideros, Myotis gr. myotis/blythii, Myotis cf. bechsteinii, Myotis emarginatus, Myotis daubentonii, Plecotus gr. auritus/austriacus, Hipsugo savii vel. Pipistrellus kuhlii/nathusii y Miniopterus schreibersii. Basándonos en las preferencias de hábitat que actualmente presentan estas especies, podemos decir que el paisaje aledaño a la cueva AGP-7 se componía en este momento de la prehistoria por una cobertura vegetal heterogénea en el que alternaban zonas de bosque con zonas de pradera.
Aunque se trata de especies que habitan actualmente en nuestro país, una comunidad actual con esta composición específica no existe hoy en día en nuestra zona del valle del Ebro, que está situada dentro de la región climática peninsular de influencia mediterránea. Sin embargo sí que se conocen asociaciones similares en otras regiones ibéricas tales como la Sierra de Guadarrama y la Sierra de Francia (en el Sistema Central), o en zonas de la Cornisa Cantábrica oriental, todas ellas caracterizadas por un clima con mayor influencia oceánica. Esta circunstancia sugiere que el clima bajo el que vivieron los habitantes de AGP-7 en esta época difería del actual probablemente en términos de humedad y pluviosidad.
