    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 Luis
    Anewstyracosternan 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.

    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 Javier
    Sauropod 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.

    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 Foundation
    Thelate 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.
