“…However, attending to the diff erences stated above with other contemporaneous dinosaurs, the following combination of characters suggests an affinity with Ornithopoda: the dorsal centra of MOR2 is moderately compressed between the narrow articular faces, and, according to Knoll (2009), without pleurocoeli and with a sinuous neurocentral suture; and caudal centra of MOR1 and MOR2 are slightly compressed between the articular faces, which range from sub-quadrangular to triangular, and without transverse processes in the middle ones. Four groups of ornithopods can be distinguished in the Lower Cretaceous of the Iberian Peninsula: small basal ornithopods related to the English taxon Hypsilophodon (e.g., Sanz et al, 1983;Ruiz-Omeñaca et al, 2012), small basal iguanodontians related to the Upper Cretaceous rhabdodontids (Dieudonné et al, 2016), dryosaurids related to the English taxon Valdosaurus (e.g., Galton, 2009), and diverse large non-hadrosaurid styracosternans (e.g., Gasca et al, 2014;Gasulla et al, 2014Gasulla et al, , 2015Verdú et al, 2015;Fuentes et al, 2016), the latter being the group most frequently found in the fossil record. It should be noted that some Lower Cretaceous Iberian fossils identifi ed as basal ornithopods, indeed, might be basal ornithischians (Pereda-Suberbiola et al, 2012).…”

“…The fossils of large ornithopods are the most abundant among those belonging to dinosaurs in the Lower Cretaceous of the Iberian Peninsula (Pereda-Suberbiola et al, 2012;Gasca et al, 2014;Gasulla, 2015;Verdú, 2017;Alcalá et al, 2018). Based on current knowledge, the diversity of this type of dinosaur (all of which are considered Styracosterna) in this stratigraphic range is composed of Magnamanus soriaensis Fuentes et al, 2016 in the upper Hauterivian-lower Barremian of Soria province (Fuentes et al, 2016); Iguanodon galvensis Verdú et al, 2015 in the lower Barremian of Teruel province (Verdú et al, 2015); Iguanodon bernissartensis Boulenger in Van Beneden, 1881, Mantellisaurus atherfieldensis (Hooley, 1925), and Morelladon beltrani Gasulla et al, 2015 in the upper Barremian of Cuenca (with the exception of the last taxon) and Castellón provinces (Sanz et al, 1982;Llandres et al, 2013;Gasulla et al, 2014Gasulla et al, , 2015Gasulla, 2015;Sanguino & Buscalioni, 2018); and Proa valdearinnoensis McDonald et al, 2012 in the Albian of Teruel province (McDonald et al, 2012). In addition, another styracosternan described in the lower Barremian of Teruel province, 'Delapparentia turolensis' Ruiz-Omeñaca, 2011, is generally considered a nomen dubium (Norman, 2015;Verdú et al, 2017).…”

We report some large ornithopod vertebrae from two upper Hauterivian-lower Barremian (Lower Cretaceous) localities in El Castellar (Maestrazgo Basin, Teruel, Spain). These fossils have been studied systematically as well as morphometrically using a multivariate analysis in order to analyse the diversity of the sample. In fact, principal component analysis has been demonstrated as an useful tool for establishing affinities in isolated iguanodontian vertebrae, at least when size eff ect is not removed from the analysed dataset. As result of this study, two large indeterminate styracosternans are distinguished in the sample: a large one with platycoelus anterior caudal vertebrae related to the genera Magnamanus and Iguanodon, and a middle-sized one with longer-than-high dorsal vertebrae and amphicoelus anterior caudal vertebrae related to Morelladon. Such diversity of large ornithopods observed in the upper Hauterivian-lower Barremian of the Maestrazgo Basin is similar to that previously observed in western Cameros Basin and it demonstrates the presence of at least two diff erent forms of styracosternan in this stratigraphic range of the Iberian Peninsula.

Anatomy, taphonomy, and phylogenetic implications of a new specimen of Eolambia caroljonesa (Dinosauria: Ornithopoda) from the Cedar Mountain Formation, Utah, USA

et al. 2017

View full text Add to dashboard Cite

BackgroundEolambia caroljonesa is the most abundant dinosaur in the lower Cenomanian Mussentuchit Member of the Cedar Mountain Formation of Utah, and one of the most completely known non-hadrosaurid iguanodontians from North America. In addition to the large holotype and paratype partial skulls, copious remains of skeletally immature individuals, including three bonebeds, have been referred to E. caroljonesa. Nevertheless, aspects of the postcranial anatomy of this taxon, particularly the pelvic girdle, have remained ambiguous due to the lack of associated postcranial material of larger, more mature individuals.Methodology/Principal findingsHere we describe a recently discovered associated partial postcranial skeleton of a large Eolambia caroljonesa. This specimen, FMNH PR 3847, provides new anatomical data regarding the vertebral column and pelvic girdle, supplementing previous diagnoses and descriptions of E. caroljonesa. A new phylogenetic analysis incorporating information from FMNH PR 3847 places E. caroljonesa as a basal hadrosauromorph closely related to Protohadros byrdi from the Cenomanian Woodbine Formation of Texas. Histological analysis of FMNH PR 3847 reveals that it represents a subadult individual eight to nine years of age. Taphonomic analysis indicates that FMNH PR 3847 was preserved in a crevasse splay deposit, along with an unusual abundance of small crocodylomorph material.Conclusions/SignificanceFMNH PR 3847 provides a wealth of new morphological data, adding to the anatomical and systematic characterization of Eolambia caroljonesa, and histological data, revealing new information on growth history in a basal hadrosauromorph. Taphonomic characterization of FMNH PR 3847 and associated vertebrate material will allow comparison with other vertebrate localities in the Mussentuchit Member of the Cedar Mountain Formation.

“…Until recently, the Early Cretaceous European fossil record of styracosternan iguanodonts was composed of basal representatives of the node-based clade Hadrosauriformes ( sensu Sereno [ 1 ]), or members of the outgroup. Delapparentia , Hypselospinus , Iguanodon , Mantellisaurus and Proa were the hadrosauriform styracosternans recognized from several Lower Cretaceous formations [ 2 – 5 ]. A recent re-evaluation of the phylogenetic relationships indicates a new subclade of non-hadrosauriform styracosternans (‘iguanodontoids’) and includes most of these previously considered European hadrosauriforms.…”

“…Presently, the Lower Cretaceous Iberian styracosternan iguanodontians species are the lower Barremian Delapparentia turolensis [ 2 ] and Iguanodon galvensis [ 5 ], the upper Barremian Iguanodon bernissartensis and Mantellisaurus atherfieldensis [ 7 – 10 ], and the lower Albian Proa valdearinnoensis [ 3 ]. However, it should be noted that Norman [ 6 ] considers Delapparentia turolensis provisionally as a nomem dubium .…”

A New Sail-Backed Styracosternan (Dinosauria: Ornithopoda) from the Early Cretaceous of Morella, Spain

et al. 2015

View full text Add to dashboard Cite

A new styracosternan 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 de Morella Formation (Early Cretaceous, late Barremian) at the Morella locality, (Castellón, Spain). Morelladon beltrani gen. et sp. nov. is diagnosed by eight autapomorphic features. The set 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 Proa valdearinnoensis). 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.
