New Iguanodon bernissartensis Axial Bones (Dinosauria, Ornithopoda) from the Early Cretaceous of Morella, Spain

Diversity (2022)

José Miguel Gasulla Fernando Escaso Iván Narváez J. L. Sanz Francisco Ortega

Iguanodon bernissartensis is the most frequently and widely cited styracosternan ornithopod in Western Europe during the Early Cretaceous, although some of these assignments likely need to be revised to establish the true distribution of the taxon. Here, we describe a new specimen of I. bernissartensis from the upper Barremian of the Iberian Peninsula. Based on the unique combination of shared characters, the new specimen from the Arcillas de Morella Formation at Morella locality (Castellón, Spain) can be confidently referred to Iguanodon bernissartensis. These characters include parallel-sided anterior and posterior margins of the dorsal and the caudal neural spines as well as the presence of a ventral keel in the posterior dorsal centra and a broad ventral sulcus in the midline of the central surface of the most posterior sacral vertebrae. This new evidence of Iguanodon bernissartensis reinforces the knowledge about styracosternan ornithopods as the most frequently recorded dinosaur group in the Arcillas de Morella Formation.

Crocodyliformes and Testudines from the Eocene of the Duero Basin (northwestern Spain): an update of their diversity and stratigraphic context

Historical Biology (2022)

Francisco Ortega Ildefonso Armenteros Armenteros Ane de Celis Fernando Escaso Pedro Huerta Hurtado

The Palaeogene sedimentary successions of the Duero Basin host an important record of fossil vertebrates, especially mammals and reptiles. The main fossil sites are placed at the west margin (Salamanca and Zamora areas) spanning from the Lutetian to the late Priabonian; and at the southeast tip (Almazán Basin) mainly Bartonian in age. The continued study of the sites is supplying new data that will improve the chronostratigraphy and the correlation between the western and eastern regions of the basin. The diversity and phylogenetic relationships of the represented fauna have been revised in recent years with the reassignment of some remains and the diagnosis of some new taxa. Four lineages of turtles are represented: Podocnemididae (Neochelys), Carettochelyidae (Allaeochelys), Trionychidae and Testudinidae (Pelorochelon). Crocodyliform paleobiodiversity is composed of notosuchians (close to Iberosuchus) and, at least, three crocodylian lineages: Planocraniidae (Duerosuchus), Alligatoroidea (Diplocynodon) and Crocodyloidea ('Asiatosuchus'). The distribution of these taxa is not homogeneous throughout the basin, and a deep transformation is recognised throughout the middle Eocene. The fitting of the distribution and relationships of the reptilian fauna from the Duero Basin provides valuable information to understand some faunistic dynamics such as the endemism process of northwestern Iberia from the middle of the Eocene.

Dinosaurs and other extinct creatures in adventure booklets from the golden age of Spanish comics

Journal of Graphic Novels & Comics (2024)

Charlie Charmer Iván Narváez

Adventure comics were one of the most popular forms of escapism for young people during the harsh period following the Spanish Civil War, until they were replaced by television in the 1960s. The heroes of these comic booklets faced all sorts of threats and monsters, often including dinosaurs, pterosaurs, and other animals from the past which proved ideal for personifying all the horrors that readers had to deal with on a daily basis, so they were destroyed in the cruellest way possible. As these were extinct and largely unknown creatures, the scriptwriters and artists had to use a considerable amount of imagination to fill in their many gaps. A sample of about five hundred pages of Spanish comic booklets featuring different reptiles of the past is analysed here to examine which species were favoured by readers, their role in these comics, and the general palaeontological ignorance that they often revealed. These results are also compared with similar studies of different geographical and temporal scope in order to assess similarities and differences.

Problèmes de la gouvernance énergétique en Équateur

Problèmes d Amérique latine (2005)

Guillaume Fontaine Iván Narváez

Publicado en “Problemes de la gouvernance energetique en Equateur », in David Garibay e Isabelle Rousseau (Coord.), « Dossier : les hydrocarbures dans les Ameriques : les nouvelles regles du jeu », « Problemes d Amerique Latine », 57-58, 2005, Paris, Ed. Choiseul. Resume A partir d une recherche de deux ans sur les conflits ecologiques pour l exploitation d hydrocarbures en Amazonie equatorienne et d une serie de debats publics sur la relation entre petrole et developpement durable en Equateur, cet article tente de degager les lignes force qui traversent la situation actuelle de l industrie petroliere nationale. Nous rappelons, dans une premiere partie, l histoire recente de la politique petroliere, les reformes du regime contractuel et l evolution de la part de la rente percue par l Etat ; ensuite nous analysons les consequences de la privatisation de fait d une partie de ce secteur, les defis poses par la modernisation de l entreprise nationale, Petroecuador, puis l incidence des conflits ecologiques sur la gouvernance energetique et la protection de l environnement.

New Crocodyliforms from Southwestern Europe and Definition of a Diverse Clade of European Late Cretaceous Basal Eusuchians

PLoS ONE (2015)

Iván Narváez Christopher A. Brochu Fernando Escaso Adán Pérez‐García Francisco Ortega

The late Campanian-early Maastrichtian site of Lo Hueco (Cuenca, Spain) has provided a set of well-preserved crocodyliform skull and lower jaw remains, which are described here and assigned to a new basal eusuchian taxon, Lohuecosuchus megadontos gen. et sp. nov. The reevaluation of a complete skull from the synchronous site of Fox-Amphoux (Department of Var, France) allows us to define a second species of this new genus. Phylogenetic analysis places Lohuecosuchus in a clade exclusively composed by European Late Cretaceous taxa. This new clade, defined here as Allodaposuchidae, is recognized as the sister group of Hylaeochampsidae, also comprised of European Cretaceous forms. Allodaposuchidae and Hylaeochampsidae are grouped in a clade identified as the sister group of Crocodylia, the only crocodyliform lineage that reaches our days. Allodaposuchidae shows a vicariant distribution pattern in the European Late Cretaceous archipelago, with several Ibero-Armorican forms more closely related to each other than with to Romanian Allodaposuchus precedens.
