The Ventian mammal age (Latest Miocene): present state
2013
[EN] The Ventian land mammal age includes most of the Spanish faunas assigned to the biochronologic unit MN 13. It is correlatable with the Messinian, although it may include, in its latest part, Early Pliocene faunas. We propose that the Ventian begins with the fi rst occurrence of the Muridae genus Stephanomys (7 Ma, paleomagnetic dating from El Bunker, Teruel basin), well recorded in Teruel basin, and ends with the appearance of Promimomys (ca. 5 Ma), also registered in the Teruel basin. We suggest a new reorganization of the Ventian. The first subdivision corresponds to the zone M (Dam et al., 2001). The second, zone N, is proposed here for the first time, being equivalent to the zone w…
Characterization of coelacanth scales from the Early Cretaceous freshwater locality of Las Hoyas, upper Barremian (Cuenca, Spain)
2020
Coelacanths are rare, mostly marine fishes, but the species from the Lower Cretaceous Spanish locality of Las Hoyas (Barremian) is a freshwater form and we know almost nothing about it. The Las Hoyas specimens are very rare and relatively incomplete, but there are still many things we can learn from the isolated skeletons and scales. First, the coelacanth scales were distinguished from other superficially similar scales (i.e., other “amioid” scales). Coelacanth scales are distinguished by the presence of a smooth central surface, a particular pattern of arrangement of concentric growth cessation marks, and mainly a relatively short posterior field with thick elongated ridges. Only a few art…
Early Aptian corals from Peñascal (Bilbao, N Spain)
2020
From two horizons in the lower Aptian Peñascal limestone Formation south of Bilbao 22 coral species are reported. The corals belong to the scleractinian families Actinastraeidae, Eugyridae, Haplaraeidae, Latomeandridae, and Solenocoeniidae, and the octocorallian family Helioporidae. The stratigraphic distribution of the species lies between the Berriasian to Cenomanian, but most species have a distribution between the Barremian and Albian. The faunas show most palaeobiogeographical relationship to faunas from the Hauterivian to Albian of the European Boreal, the Western Atlantic and the Western Tethys.
Trending topics in Spanish Palaeontology: Contributions from the XI Encuentro de Jóvenes Investigadores
2020
The present volume represents a series of synthetic works presented at the “XI Encuentro de Jóvenes Investigadores en Paleontología”, which took place in Atarfe (Granada, Spain) on April 2013. During this meeting, more than thirty contributions were presented, offering a representative sample of the palaeontological state-of-the-art research currently developed in Spain. A small selection of these contributions is here presented, highlighting than most of them are first-authored by early-stage Spanish researcher who attended the aforementioned meeting. As stated above, our planet has evolved since its origin, in a similar wat that Palaeontology has evolved during the las decades. This evolu…

2021
Nos encontramos ante una nueva obra de Francisco Pelayo, quien en los últimos años viene realizando una interesante labor de análisis y caracterización histórica de la Paleontología española, adecuadamente enmarcada en la situación europea de esta ciencia. Este trabajo no es una continuación estricta del libro titulado Del Diluvio al Megaterio de este mismo autor (ver Noticias Paleontológicas 29), pero sí que existe cierta continuidad desde el punto de vista del análisis de las ideas paleontológicas en España.
 El título y subtítulo de la obra son suficientemente expresivos, mostrando claramente cuál va a ser el hilo conductor que se propone en la obra y que, de una manera precisa, es …

2021
Se trata de un libro dirigido al público en general, donde se van describiendo los diversos avatares que los autores han ido superando, hasta acceder, estudiar y describir el gran tesoro geológico y paleontológico que, ya se presumía, estaba contenido en los materiales geológicos bajo la montaña ordovícica.
La valoración del patrimonio geológico y paleontológico como herramienta de gestión: el Modelo FOPALI
2019
El compromiso con la preservación del patrimonio geológico y paleontológico ha constituido una prioridad para el Museo Paleontológico de Elche – Fundación Cidaris desde los inicios de su actividad. En este contexto se ha desarrollado una estrategia de trabajo (FOPALI) en el que la valoración patrimonial es concebida como una herramienta de gestión. Se exponen aquí las bases metodológicas del modelo FOPALI y las técnicas de análisis aplicadas para ofrecer a los gestores del patrimonio la información necesaria para establecer prioridades en la investigación, conservación y difusión del patrimonio geológico y paleontológico.
Reconstruction of the internal structure of the pore system of a complex dinosaur eggshell (Megaloolithus siruguei)
2013
Despite the many reconstructions of fossil material that have recently appeared in the literature, dinosaur eggshells have never been reconstructed using computing techniques. Using the EMAC 3-D modelling methodology, we reconstruct a section of the Late Cretaceous Megaloolithus siruguei eggshell, which has a particularly complex pore system, exhibiting an intricate network of vertical, oblique, and horizontal pores.
LOCHKOVIAN TO PRAGIAN (LOWER DEVONIAN) NERITIC OSTRACODES FROM NIGÜELLA (ZARAGOZA, IBERIAN CHAINS, NE SPAIN)
2021
Lochkovian and Pragian ostracodes from the area of Niguella (Iberian Chains), which is a key area for supra-regional correlation in the Early Devonian, are described for the first time. 12 ostracode taxa from the sections Ni4 and Ni2 could be identified. The silicified ostracodes of Eifelian Ecotype are low in biodiversity, have few individuals, and are comparatively poorly preserved. Characteristic taxa of the Devonian occur. Thus, the faunas show general relations to most European Early Devonian ostracode faunas. Closer relations exist to the Eastern Guadarrama. Polyzygia kroemmelbeini LeFevre & Weyant, 1967 and P. grekoffi Weyant, 1980 are found in the basal Pragian for the first time. B…
