“…Unfortunately, no three-dimensional, articulated fossil detailing the spatial relationships of the coracoid, scapula, and furcula has been found. Modern birds have saddle-shaped (heterocoelous) articulations between cervical vertebrae, and this is known to have developed at least in the anterior portion of the neck in several enantiornithine taxa (Sanz et al, 2001;Zhang et al, 2004;Zhou et al, 2008). This innovation may have enhanced the functional performance of the latter.…”

“…The ischial blade of Qiliania resembles those of Eoenantiornis buhleri (Zhou, Chiappe & Zhang, 2005) and Sinornis in its ‘knife‐like’ morphology and lack of an obturator process, opposing the condition reported in Concornis lacustris (Sanz, Chiappe & Buscalioni, 1995; Sanz et al ., 2002). As in Gobipteryx minuta (Kurochkin, 1996), GMV‐2158, and GMV‐2159 (another indeterminate juvenile enantiornithine from the Early Cretaceous of China; Chiappe et al ., 2007) but in contrast to Longipteryx chaoyangensis (Zhang et al ., 2001), Pengornis houi (Zhou et al ., 2008), Protopteryx fengningensis (Zhang & Zhou, 2000), Shenqiornis , Sinornis (Sereno et al ., 2002), ‘bird 1’ of a probable regurgitated pellet from the Early Cretaceous of Spain (LH 11 386; Sanz et al ., 2001; Chiappe, 2007), and possibly Bolouchia zhengi (Zhou, 1995b), the distal end of the pubis of Qiliania lacks a boot. Eoenantiornis does possess a pubic boot, although it is proportionately smaller than in Pengornis , Shenqiornis , and Sinornis .…”

In recent years, the Lower Cretaceous (Aptian) Xiagou Formation has yielded approximately 100 avian partial skeletons, many with soft-tissue traces, from sites in the Changma Basin of Gansu Province, north-western China. The most abundant taxon amongst these is the ornithuromorph Gansus yumenensis, but enantiornithines have also been identified in the sample. Here we describe two incomplete, semi-articulated appendicular skeletons, the first consisting of a partial left pelvic girdle and complete pelvic limb, and the second comprised of a nearly complete right pelvic limb. Both specimens bear characteristics diagnostic of Enantiornithes, and are referred to a new taxon, Qiliania graffini gen. et sp. nov. The exceptional, three-dimensional preservation of these specimens (compared to the crushed, nearly two-dimensional condition of most other Early Cretaceous avian fossils) reveals new information regarding enantiornithine anatomy, evolution, and diversity.

“…3c). La diversidad conocida es aún mayor, y se encuentran en proceso de descripción, al menos, una nueva enantiornita cuyo esqueleto se encuentra en una probable egagrópila de un dinosaurio no aviano (Sanz et al, 2001b;Chiappe et al, 2004) (fig. 3b) Lacasa-Ruiz, 2002) y un ejemplar juvenil de gran tamaño, al que no se asignó una denominación específica atendiendo a su inmadurez , pero que, dado que sobrepasa largamente en talla a la mayor parte del resto de los ejemplares ibéricos, no parece corresponder a lo que se espera de los estadios ontogenéticos tempranos de las formas conocidas hasta el momento.…”

RESUMENEl registro de restos directos de dinosaurios en la Península Ibérica ha mostrado, en los últimos años, que puede ser muy relevante para el conocimiento de distintos aspectos de la historia evolutiva del grupo y, dada la posición de la Península Ibérica, para la interpretación de la distribución de muchos de sus componentes. El registro ibérico cuenta con representantes de casi todos los grandes grupos de dinosaurios: ornitópodos, tireóforos, terópodos y saurópodos, que están bien representados, sobre todo en el tránsito Jurásico-Cretácico (Kimmeridgiense-Berriasiewe), en parte del Cretácico Inferior (Barremiense-Aptiense) y en el final del Cretácico Superior (Campaniense-Maastrichtiense).El conjunto de ornitisquios está compuesto por tireóforos, de los que se han identificado dos estegosaurios (Dacentrurus y Stegosaurus) y tres anquilosaurios (Dracopelta, Polacanthus y Struthiosaurus) y ornitópodos: hipsilofodóntidos, iguanodontia basales (Rhabdodon); driosáuridos, camptosáuridos (Draconyx y Camptosaurus), iguanodontoideos (Iguanodon) y hadrosáuridos (Pararhabdodon). Además existe un gran número de formas de asignación dudosa o aún por describir.El registro de saurópodos está fundamentalmente compuesto por formas cercanas al nodo Neosauropoda (Lourinhasaurus, Dinheirosaurus, Galveosaurus y Losillasaurus) y titanosauriformes (Aragosaurus, Lusotitan y Lirainosaurus), además de una serie de formas nuevas en fase de descripción, como los saurópodos de Riodeva (Teruel), Peñarroya de Tastavins (Teruel) y Morella (Castellón).El conjunto de géneros de terópodos ibéricos está constituido por el ceratosaurio Ceratosaurus, el espinosauroide Torvosaurus, los carnosaurios Lourinhanosaurus y Allosaurus, el tiranosauroide Aviatyrannis, el ornitomimosaurio Pelecanimimus, y los terópodos avianos Iberomesornis, Concornis, Eoalulavis y Noguerornis. Sin embargo, la diversidad de terópodos es mucho mayor, como muestra la abundante colección de morfotipos dentarios identificados. ABSTRACTBody fossils of the Iberian Peninsula dinosaurs are very relevant for the knowledge of several aspects of the evolutionary history of the group, and, in addition, for the interpretation of the distribution of many of its components, due to the geographic situation of the Iberian Peninsula. Almost all of the groups of dinosaurs are represented in the Iberian Peninsula record: ornithopods, thyreophorans, theropods and sauropods. These groups are present, mainly, in the transit Jurassic-Cretaceous (Kimmeridigian-Berriasian), the upper part of the Lower Cretaceous (Barremian-Aptian) and in the end of the Upper Cretaceous (Campanian-Masstrichtian).Ornithischian dinosaurs are represented by thyreophorans such as the stegosaurians Dacentrurus and Stegosaurus, the ankylosaurs Dracopelta, Polacanthus and Struthiosaurus, and ornithopods like hypsilophodontids, basal iguanodontians (Rhabdodon), dryosaurids, camptosaurids (Draconyx and Camptosaurus), iguanodontids (Iguanodon) and hadrosaurids (Pararhabdodon). Some Incertae sedis and taxa in process of d...
