Delapparentia turolensis nov. gen et sp., un nuevo dinosaurio iguanodontoideo (Ornithischia: Ornithopoda) en el Cretácico Inferior de Galve

An ornithopod dinosaur postcranial skeleton from the Early Cretaceous of Galve (Teruel province, Spain), assigned to Iguanodon bernissartensis by the French paleontologist Albert de Lapparent in 1960, is redescribed. It comes from La Maca 3 locality, early Barremian in age (Camarillas Formation) and it is made of several cervical vertebrae, fragmentary remains of the dorsal and sacral series, several caudal vertebrae, fragments of cervical, dorsal and sternal ribs, fragments of chevrons and ossified tendons, and an incomplete left hip. It has been identified as an «iguanodontid» (i.e., a non-hadrosaurid iguanodontoid) by the presence of a deep prepubic blade and the absence of antitrochanter on ilium. The skeleton represents a new iguanodontoid taxon, Delapparentia turolensis nov. gen et sp., characterized by the following autapomorphies: 1) posterior dorsal ribs with long, parallel and unfused capitulum and tuberculum, 2) ossified sternal ribs, and 3) straight and lateromedially expanded preacetabular process of ilium (convergent in Zalmoxes). It also presents a combination of anterior dorsal ribs with a pneumatic foramen, and a ischium of big size in relation to ilium.Se redescribe un esqueleto postcraneal de dinosaurio ornitópodo asignado por Albert de Lapparent en 1960 a Iguanodon bernissartensis. Procede del yacimiento de La Maca 3, de edad Barremiense inferior (Formación Camarillas), y consta de varias vértebras cervicales, restos de la serie dorsal y sacra, varias vértebras caudales, fragmentos de costillas cervicales, dorsales, y esternales, chevrones y tendones osificados, y la hemipelvis izquierda incompleta. Se ha identificado como un «iguanodóntido» (i.e. un Iguanodontoidea no Hadrosauridae) por la presencia de una lámina prepubica alta y la ausencia de antitrocánter en el ilion. Se propone a partir de este material un nuevo taxón de iguanodontoideo, Delapparentia turolensis nov. gen et sp., caracterizado por las siguientes autapomorfías: 1) costillas dorsales posteriores con capítulo y tubérculo no fusionados, 2) costillas esternales osificadas, y 3) ilion con el proceso preacetabular torsionado y expandido lateromedialmente (compartida con Zalmoxes). Además presenta una combinación de costillas dorsales anteriores con un foramen neumático, e isquion grande en relación al ilion

New material and phylogenetic position of the basal iguanodont dinosaur Delapparentia turolensis from the Barremian (Early Cretaceous) of Spain

a partial postcranial skeleton discovered in the 1950s near the village of Galve (Teruel Province), within the Camarillas Formation. Recently, new remains from the same individual have been recovered, and these are described here. Furthermore, after first-hand examinations of the holotype, the phylogenetic position of this taxon has been analysed for the first time, and its diagnosis is emended. Delapparentia turolensis is a large-sized, basal iguanodont which presents an autapomorphic, unusually high axial neural spine and a unique combination of postcranial characters. The ilium morphology differs from that of other basal iguanodonts and relates Delapparentia to the Valanginian Barilium dawsoni from England, with whom it shares two synapomorphies. In our phylogenetic analysis Delapparentia is recovered in a polytomy with Kukufeldia, Lanzhousaurus, Barilium and the clade equivalent to Iguanodontoidea. Delapparentia turolensis Ruiz-Omeñaca, 2011 es el único taxón iguanodonte definido en el Barremiense de España. Está descrito a partir de un esqueleto postcraneal parcial descubierto en la década de 1950 próximo al pueblo de Galve (provincia de Teruel), dentro de la Formación Camarillas. Recientemente, se han recuperado nuevos restos del mismo individuo que se describen aquí. Además, tras examinar de primera mano el holotipo, se ha analizado la posición filogenética de este taxón por primera vez además de enmendar su diagnosis. Delapparentia turolensis es un iguanodonte basal de gran tamaño, que presenta una espina neural axial autapomórfica, al ser inusualmente alta, y una combinación única de caracteres postcraneales. La forma del ilion es diferente de la de otros iguanodontes basales y relaciona a Delapparentia con Barilium dawsoni del Valanginiense de Inglaterra, al compartir de forma exclusiva dos sinapomorfías. En nuestro análisis filogenético Delapparentia se sitúa en una politomía con Kukufeldia, Lanzhousaurus, Barilium y el clado equivalente a Iguanodontoide

Delapparentia turolensis Ruiz-Omeñaca, 2011 is the only iguanodont taxon erected in the Barremian of Spain.

«Pleurocoelus» valdensis Lydekker, 1889 (Saurischia, Sauropoda) from the Lower Cretaceous (Barremian) of the Iberian Peninsula

One fragmentary sauropod isolated tooth from the Upper Barremian-Lower Aptian (Artoles Formation) of Vallipón (Castellote, Teruel province, Spain) is described. It has a «parallel-sided» crown and a «compressed cone-chisellike » general form. This tooth resembles the teeth from the Lower Barremian of Boca do Chapin (Estremadura province, Portugal) and Galve (Teruel province) described as Pleurocoelus valdensis/Astrodon valdensis and cf. Astrodon sp., respectively. The Portuguese and Spanish teeth are compared with the teeth of Pleurocoelusvaldensis from England, and Astrodon johnstoni and Pleurocoelus nanus from Maryland (USA), and they show similarities with the English species. Due to P. valdensis and P. nanus could not be congeneric, «Pleurocoelus» valdensis is put with quotation marks. «P.» valdensis is based on several isolated teeth from the Berriasian-Valanginian of Sussex and the Barremian of the Isle of Wight, but no holotype was designated, and all those teeth could represent two or more different sauropods species. The specific name is reserved to compressed cone-chisel-like teeth with enamel ornamented with irregular longitudinal ridges, probably pertaining to brachiosaurid sauropod

VIM-Klebsiella oxytoca outbreak in a Neonatal Intensive Care Unit. This time it wasn't the drain

Objective:We describe an outbreak of VIM-carbapenemase-K. oxytoca (VIM-Kox) in a NICU Study design: Prospective Epidemiological Surveillance:            a) Systematically (weekly screening cultures) or on admission, if the patient had a history of previous colonization by VIM-Kox.            b) Clinical cultures, done if infection was suspected.            c) Other possible microorganism sources were investigated: their mothers (rectal microbiota), milk packages and preparation apparata in the lactodietary section, echocardiagram transductors, cribs, the sinks (faucets and drains), washing bowls, etc.Molecular typing was performed using the DiversiLab (bioMérieux) system on all VIM-Kox  isolated from environment or patients (one by neonate). Results:We identified 20 VIM-Kox cases, the most only presented colonization, but 4 showed infection. Three of the ten sinks (drains) in our NICU, were positive for VIM-Kox.  Another four drains harbored P.aeruginosa, S. maltophilia and/or Enterobacter sp.Nevertheless the VIM-Kox bacteria in the sinks (drains) were not the same as those in the patients, who showed three different strains Conclusions:- A VIM-Kox colonization or infection outbreak in a NICU is described.-Rather than environment, not even drains, the source of the outbreak was other patients.-The outbreak was relatively brief, as a result of the rapidness with which appropriate measures were taken and followed

Nuevos datos sobre los dinosaurios terópodos (Saurischia: Theropoda) del Cretácico superior de los Pirineos Sur-Centrales (Huesca y Lleida)

Six new theropod teeth recovered trom the Blasi 1-3 sites (Upper Maastrichtian) in Arén (Huesca province, Spain) are described and added to the twenty six teeth already known from these and other five localities of Late Campanian-Early Maastrichtian age from the Arén and Tremp formations (Figuero1a 2, Fontllonga 6, L'Abeller, Montrebei and Vicari 4, Lleida province). Eleven theropod teeth morphotypes are recognised: one belonging to a big size theropod of indeterminate family (Theropoda indet.), one small Coelurosauria indet. with unserrated teeth, the enigmatic Euronychodon sp, and eight morphotypes of cf. Dromaesauridae indet. with different denticle morphology and serration density (which would represent four five different taxa). The tooth previously described in the Upper Campanian of Lleida as "Richardoestesia Like" could also be assigned to cf. Dromaeosauridae indet. Theropod diversity in our sites is apparently similar to that of the rest of Europe, and increases through the Campanian-Maastrichtian transition, although our small samples is biased towards the youngest sites
