Dakosaurus and Plesiosuchus are characteristic genera of aquatic, large-bodied, macrophagous metriorhynchid crocodylomorphs. Recent studies show that these were apex predators in marine ecosystems during the latter part Late Jurassic, with robust skulls strong bite forces optimized for feeding on large prey.Here we present comprehensive osteological descriptions systematic revisions type species both genera, doing so resurrect genus manselii. Both diagnosed numerous autapomorphies. maximus...

Machimosaurus was a large-bodied genus of teleosaurid crocodylomorph, considered to have been durophagous/chelonivorous, and which frequented coastal marine/estuarine ecosystems during the Late Jurassic. Here, we revise based on previously described specimens species within this genus. We conclude that there were three European another taxon in Ethiopia. This conclusion is numerous lines evidence: craniomandibular, dental postcranial morphologies; differences estimated total body length;...

Abstract Some Cretaceous dinosaur taxa with a broad enough record on the continents of northern hemisphere (Laurasia) or in southern (Gondwana) have been interpreted as Laurasian Gondwanan origin. The occasional presence these outside Laurasia Gondwana respectively has frequently explained terms dispersal from their place origin by means land bridges that are indeterminate location and character. One example such event is provided Early dinosaurs Europe Africa. Certain European having...

La Cantalera is an accumulation site for fossil vertebrates consisting mainly of teeth and isolated postcranial remains. It has the greatest vertebrate biodiversity any from Hauterivian-Barremian transition in Iberian Peninsula. Up to now, 31 taxa have been recognized: osteichthyan (Teleostei indet.), two amphibians (Albanerpetonidae indet. Discoglossidae a chelonian (Pleurosternidae? lizard (Paramacellodidae? four crocodylomorphs (cf. Theriosuchus sp., Bernissartiidae indet.,...

Blasisaurus canudoi gen. et sp. nov. is described on the basis of disarticulated skull and lower jaw remains found in Blasi 1 locality Arén (Huesca, south-central Pyrenees Spain), located upper part Formation, late Maastrichtian age. This new lambeosaurine hadrosaurid characterized by a jugal combining hook-like dorsal edge posterior process narrow, D-shaped infratemporal fenestra. differs from Arenysaurus 3 site mainly absence secondary ridges dentary teeth, Koutalisaurus (probably junior...

Se redescribe un esqueleto postcraneal de dinosaurio ornitópodo asignado por Albert Lapparent en 1960 a Iguanodon bernissartensis. Procede del yacimiento La Maca 3, edad Barremiense inferior (Formación Camarillas), y consta varias vértebras cervicales, restos la serie dorsal sacra, caudales, fragmentos costillas dorsales, esternales, chevrones tendones osificados, hemipelvis izquierda incompleta. ha identificado como «iguanodóntido» (i.e. Iguanodontoidea no Hadrosauridae) presencia una...

At least four parallel trackways of medium-sized and robust ornithopods are described from the Upper Jurassic Tereñes tracksite in Asturias (N. Spain). While tracks small gracile common record, large very rare this period. Ornithopod gregarious behavior has been recorded many Cretaceous ichnoassemblages, but there few examples Jurassic, these always relate to individuals. The Asturian quite different known ichnogenera, they not sufficiently well preserved propose a new one. Medium-large with...

ABSTRACT A new species of a ziphodont crocodyliform is described on the basis newly-discovered material from Late Cretaceous (Campanian) Sierra Perenchiza Formation Valencia, Spain. It referred to genus Doratodon as D. ibericus sp. nov. To date, (type-species carcharidens) was only known by fragmentary cranial remains Campanian Muthmannsdorf (Austria). This previously regarded either goniopholid or hsisosuchid within Mesoeucrocodylia, but phylogenetic analysis suggests that member...

En Galve (Teruel) hay más de 50 localidades con restos vertebrados continentales en las Formaciones Higueruelas (Titónico), Villar del Arzobispo (Titónico superior-Berriasiense medio), El Castellar (Hauteriviense terminal-Barremiense basal) y Camarillas (Barremiense inferior).Por tanto, «Galve» no es un único yacimiento mesozoicos, sino una localidad numerosos yacimientos intervalo Titónico-Barremiense, que geológicamente pertenecen a la Cuenca cretácica inferior Maestrazgo (Cordillera...

ABSTRACT Arenysaurus ardevoli is a lambeosaurine hadrosaurid from the late Maastrichtian of Arén (Huesca, northern Spain) that has recently been described. The holotype first and most complete with braincase Europe. In this paper, we present description postcranial skeleton, which was poorly described when taxon named because it partially unprepared, new information on several cranial bones (jugal, maxilla, dentition). A phylogenetic analysis closely related Blasisaurus canudoi, also Arén,...

Fragmentary remains, including cervical vertebrae and limb bones, of a large pterosaur from the Upper Cretaceous Tous, province Valencia (Spain), are described. The material was recovered lacustrine beds in upper part Calizas y Margas de Sierra Perenchiza Formation, which is probably Maastrichtian age. Six fragments allow reconstruction anatomy mid-series cervicals animal. general morphology closely similar to that long-necked Azhdarchidae. Compared other azhdarchids, shows minor differences...

Dinosaur footprints occur in shallow marine sedimentary units of the Berriasian Villar del Arzobispo Formation Aliaga basin, NE Spain. Las Cerradicas is a small outcrop (25 m2), near Galve, with four dinosaur trackways. Three tridactyl trackways indicate bipedal animals, and have parallel orientation. A fourth or‐nithopod trackway indicates quadrupedal animal smallest among any reported literature (L = 23 cm, W cm pes tracks). It has manus prints that are oval‐shaped impressions. These other...

Therangospodus oncalensis is a Berriasian theropod ichnotaxon from the Cameros Basin (Soria Province, Spain). We discovered new trackways assigned to this during cleaning and conservation works at type locality (Fuentesalvo), enabling us describe it more precisely. was made by medium-sized dinosaur characterized single tapering pad on each toe, rounded heel impression narrow trackway. In addition having similar morphometric characteristics, most of Fuentesalvo site show comparable size...

In the latest Maastrichtian, European hadrosauroid fauna was more diverse than those of North America and Asia. The record hadrosaurid dentaries is an example this diversity, most sites with mandibular remains are located in Ibero-Armorican Realm. Within Iberian Peninsula, Tremp Basin (South Central Pyrenees). Two three valid taxa defined basin from Blasi (Arén, Huesca province): Arenysaurus ardevoli (Blasi-3) Blasisaurus canudoi (Blasi-1). A new locality (Blasi 3.4) has provided a dentary...

Delapparentia turolensis Ruiz-Omeñaca, 2011 is the only iguanodont taxon erected in Barremian of Spain. It described on basis a partial postcranial skeleton discovered 1950s near village Galve (Teruel Province), within Camarillas Formation. Recently, new remains from same individual have been recovered, and these are here. Furthermore, after first-hand examinations holotype, phylogenetic position this has analysed for first time, its diagnosis emended. large-sized, basal which presents an...

We herein describe the biggest theropod tooth hitherio found in Spain.The (IPS-G1) comes from Villar del Arzobispo Formation (Upper Tithonian-Middle Berriasian) Galve Sub-basin.The specimen is a nearly complete maxillary with FABL of 34 mrn and DSDI = 1.Considering its geological age crown morphology (including size), it most likely that belongs to an allosauroid.This clade theropods was present Late Jurassic Portugal Early Cretaceous (Bemasian Barremian) England.The represents first...

Evidence of the coexistence hadrosaurine and lambeosaurine dinosaurs in upper Maastrichtian Iberian Peninsula (Arén, Huesca, Spain). Many cranial postcranial remains hadrosaurid ornithopods from have been recovered Arén (Huesca, Spain) sites Blasi 1–5. Three these remains, found at 1 (Arén Formation), 4 5 (Conques Formation) are jugals only described Western Europe. The differ those Telmatosaurus transsylvanicus (Nopcsa, 1900) by being more slender presenting an anterior process...
