A New Sail-Backed Styracosternan (Dinosauria: Ornithopoda) from the
Early Cretaceous of Morella, Spain.
PLoS ONE 10(12): e0144167.
doi:10.1371/journal.pone.0144167

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.
