Fiesta y urbanismo. Valencia en los siglos XVI y XVII
2017
El objetivo principal de la presente tesis doctoral se centra en el análisis de la influencia que ejerció la fiesta como elemento transformador de la ciudad de Valencia durante los siglos XVI y XVII. Nuestra investigación se configuró a través de un estudio bicéfalo en el que por un lado tratamos de profundizar en el urbanismo valenciano y por otro, en el mundo festivo. Basándonos en algunas investigaciones que abarcaban el periodo medieval valenciano, como las regestas de María Milagros Cárcel Ortí, en las que trataban de exponer la importancia de la relación de estos dos campos de estudio, observamos que había la posibilidad de una continuación de este tipo de transformación urbana durant…
New skulls of the basal sauropodomorph Plateosaurus trossingensis from Frick, Switzerland: is there more than one species?
2021
The Triassic basal sauropodomorph Plateosaurus trossingensis is well-known from mass accumulations at the German localities of Trossingen and Halberstadt and the Swiss locality of Frick, and is significant especially regarding its ta-phonomy and proposed developmental plasticity. These implications, however, rely on the assumption that this material derives from a single species, which has been questioned. Here we describe new skull material from Frick including eight complete and six partial skulls, more than doubling the number of known skulls of P. trossingensis. This exceptional sample size allows for gaining a deeper understanding of variability that may occur in a single species. The …
Data from: Revision of the genus Anasibirites Mojsisovics (Ammonoidea): an iconic and cosmopolitan taxon of the late Smithian (Early Triassic) extinc…
2016
The family Prionitidae Hyatt represents a major component of ammonoid faunas during the Smithian (Early Triassic), and the genus Anasibirites Mojsisovics is the most emblematic taxon of this family. Its stratigraphical range is restricted to the beginning of the late Smithian (Wasatchites distractus Zone). The genus is also characterized by an unusual cosmopolitan distribution, thus contrasting with most earlier Smithian ammonoid distributions that were typically restricted by latitude. Because the late Smithian witnessed an extinction of the nekton (e.g. ammonoids, conodonts) whose amplitude is equal to or larger than that of the end-Permian crisis, the number of valid species that should …
Data from: There is no general model for occlusal kinematics in conodonts
2015
Knowledge of conodont element function is based largely on analysis of morphologically similar P1 elements of few comparatively closely related species known from abundant articulated remains. From these, a stereotypical pattern of rotational occlusion has been inferred, leading to the suggestion that this may represent a general model for ozarkodinin P1 elements at the very least. We test the generality of this occlusal model through functional analysis of Pseudofurnishius murcianus P1 elements which, though superficially similar to homologous elements in gnathodids, evolved their platform morphology independently, through a different mode of morphogenesis, and in a different topological p…
Aetosaur pes from the Upper Triassic of Krasiejów (Poland), with remarks on taxonomy of isolated bones
2021
The incomplete, articulated, right pes of an aetosaur, extracted from the lower bone-bearing horizon of the Krasiejów Late Triassic site, is larger than any other, known from among the Aetosauria. Its individual bones resemble those of at least three genera: Desmatosuchus (astragalus), Typothorax (ungual phalanges), and Stagonolepis (metatarsals). This underscores the highly speculative nature of the taxonomical classification of isolated postcranial bones and makes it impossible to assign the limb to any particular genus. The phalangeal formula is 2-3-4-5-?; for the fifth finger: 2/3/4 is possible. The anatomy of the pes indicates adaptation for digging.
Innovación social en patrimonio cultural y museos de la seda en Europa: una mirada conectada con las industrias creativas
2019
Esta contribución se enmarca dentro del proyecto H2020 Silknow que coordina la Universitat de València a través de un equipo multidisplicinar conformado por investigadores de las TIC y del ámbito de las humanidades y de las ciencias sociales. Hoy el concepto de patrimonio cultural está más que nunca ligado al presente, como punto de partida que nos vincula con nuestro pasado cultural a través del acto consciente de preservar y legar a las generaciones futuras, convirtiendo a la sociedad en custodia. Este acto emerge con la ambición de permanecer en un mundo cada vez más cambiante y mutable, pero en medio de esta corriente surge cada vez con más presencia la apreciación del patrimonio no sol…
Pelvic girdle morphology in Stagonolepis, with remarks on aetosaur systematics
2022
In recent years, the Upper Triassic deposits at Krasiejów (south-west Poland) have yielded several tetrapod taxa, both aquatic and terrestrial. Stagonolepis olenkae is one of the terrestrial vertebrates recovered there; a quadrupedal, armoured aetosaur, which belonged to the crocodile-line archosaurs with a characteristic shovel-shaped snout. Several previous studies (osteological, histological and taphonomic) have attempted to understand the mode of life, growth pattern and possible dimorphism of this species and on this basis, to interpret palaeoecological, palaeoclimatic and stratigraphical implications. So far, the pelvic girdle of S. olenkae from Krasiejów remained undescribed. Here, t…
Étude des traces de pas de vertébrés du Permien et du Trias d'Ardèche. Enjeux et perspectives.
2022
Le département de l'Ardèche estremarquable car il offre un accès privilégié auxroches sédimentaires permiennes et triasiques danslesquelles abondent les traces de vertébrés fossiles.Une vingtaine de localités et plus de 1500empreintes de pas ont déjà été recensées le longd'une succession sédimentaire affleurant entrePrivas et Les Vans. Ce patrimoine ichnologique,reconnu internationalement, documente le passagede grands groupes de reptiles en terres ardéchoises,incluant essentiellement des représentants basauxde la lignée des crocodiles (pseudosuchiens) et de lalignée des oiseaux (dinosauriformes et dinosaures),ainsi que quelques membres de la lignée des lézards/serpents (lépidosauromorphes)…
