Publicación Nuevas Tecnologías en la Enseñanza: BIOINNOVA traspasa fronteras: plataforma en abierto para la distribución del conocimiento sobre biodiversidad(Universidad Nacional de Educación a Distancia (España). Facultad de Ciencias, 2017-01-01) Novo Rodríguez, Marta; Aquilino Amez, Mónica; Pérez Martín, José Manuel; Planello Carro, María del Rosario; Herrero Felipe, Óscar; Escaso Santos, Fernando; Ortega Coloma, Francisco Javier; Narváez Padilla, IvánPublicación A new Crocodyloidea from the middle Eocene of Zamora (Duero Basin, Spain)(Wiley, 2024-03-05) Narváez Padilla, Iván; Celis, Ane de; Escaso Santos, Fernando; Martín de Jesús, Santiago; Pérez García, Adán; Ortega Coloma, Francisco JavierThe eusuchian crocodyliforms recorded in the Eocene levels of the Spanish Duero Basin belong to three lineages: Planocraniidae, with the species Duerosuchus piscator; Alligatoroidea, represented by several specimens of the genus Diplocynodon; and Crocodyloidea, which includes several specimens traditionally attributed to Asiatosuchus. The genus Asiatosuchus, established in 1940 based on a middle Eocene species from Mongolia, has subsequently served as a wastebasket taxon for Paleogene remains belonging to several species, not only from Asia but also belonging to the European and North American records. Many of these species are known by highly fragmentary remains, sharing the presence of characters such as a flat and triangular skull, and long symphyses in the lower jaw, recognized as characteristic for the crocodyloids. In addition to isolated cranial remains, among the material traditionally attributed to Asiatosuchus at the Duero Basin stands out a nearly complete skull and a left mandible, from the middle Eocene area of Casaseca de Campeán (Zamora Province). The present study analyses in detail these specimens, previously reported during the 1980s, but analyzed in a very preliminary way. They are included for the first time in a phylogenetic analysis to establish the systematic position of this Spanish form. The results confirm that it corresponds to a new species of basal crocodyloid, defined here as Asiatosuchus oenotriensis sp. nov.Publicación A New Sail-Backed Styracosternan (Dinosauria: Ornithopoda) from the Early Cretaceous of Morella, Spain(Public Library of Science, 2015-12-16) Gasulla, José Miguel; Escaso Santos, Fernando; Narváez Padilla, Iván; Ortega Coloma, Francisco Javier; Sanz, José LuisAnewstyracosternan ornithopod genus and species is here described based on a partial postcranial skeleton and an associated dentary tooth of a single specimen from the Arcillas deMorella Formation (Early Cretaceous, late Barremian) at the Morella locality, (Castellón, Spain). Morelladon beltrani gen. et sp. nov. is diagnosed by eight autapomorphic features. Theset of autapomorphies includes: very elongated and vertical neural spines of the dorsal vertebrae, midline keel on ventral surface of the second to fourth sacral vertebrae restricted to the anterior half of the centrum, a posterodorsally inclined medial ridge on the postacetabular process of the ilium that meets its dorsal margin and distal end of the straight ischial shaft laterally expanded, among others. Phylogenetic analyses reveal that the new Iberian form is more closely related to its synchronic and sympatric contemporary European taxa Iguanodon bernissartensis and Mantellisaurus atherfieldensis, known from Western Europe, than to other Early Cretaceous Iberian styracosternans (Delapparentia turolensis and Proavaldearinnoensis). The recognition of Morelladon beltrani gen. et sp. nov. indicates that the Iberian Peninsula was home to a highly diverse medium to large bodied styracosternan assemblage during the Early Cretaceous.Publicación Upper Jurassic sauropod record in the Lusitanian Basin (Portugal): Geographical and lithostratigraphical distribution(Coquina Press, 2017-05-01) Mocho, Pedro; Royo-Torres, Rafael; Escaso Santos, Fernando; Malafaia, Elisabete; Miguel Chaves, Carlos de; Narváez Padilla, Iván; Pérez García, Adán; Pimentel, Nuno; Silva, Bruno C.; Ortega Coloma, Francisco JavierSauropod remains are relatively abundant in the Upper Jurassic sediments of the Lusitanian Basin. These dinosaurs are recorded in several sub-basins formed during the third rifting episode related to the evolution of the Lusitanian Basin. The Kimmeridgian-Tithonian sedimentary sequence is dominated by siliciclastic deposits, indicating a continental environment. Sauropods are present all along this mainly terrestrial sequence, being recorded in the Alcobaça, Praia da Amoreira-Porto Novo, Sobral, Freixial, and the Bombarral Formations, ranging from the early Kimmeridgian to the late Tithonian. Sauropoda is the most abundant dinosaur group in the Upper Jurassic fossil record of the Lusitanian Basin and is especially well-represented in the Bombarral and Turcifal Sub-basins. Several new specimens, so far unpublished, are reported here. The sauropod fauna identified mainly includes non-neosauropod eusauropods (including turiasaurs), diplodocoids (some specimens with diplodocine affinities), basal macronarians (non-camarasaurids and camarasaurids), and titanosauriforms (some specimens with brachiosaurid affinities). Macronarians, turiasaurs and diplodocoids are generally present along the entire Kimmeridgian-Tithonian continental to transitional deposits of the Lusitanian Basin, but the known fossil record for some more exclusive groups such as camarasaurids, brachiosaurids, and diplodocines, present a more restricted stratigraphic distribution.Publicación New crocodyliforms from southwestern Europe and definition of a diverse clade of European uppermost Cretaceous basal eusuchians(Public Library of Science, 2015-11-04) Narváez Padilla, Iván; Brochu, Christopher A.; Escaso Santos, Fernando; Pérez García, Adán; Ortega Coloma, Francisco Javier; Ministerio de Economía y Competitividad. España; US National Science FoundationThelate 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 newbasaleusuchiantaxon, 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 aclade identified as the sister group of Crocodylia, the only crocodyliform lineage that reaches our days. Allodaposuchidae shows avicariant 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.
