They come from the Cameros Basin in the north of Spain and were collected from the red clays of the Castrillo de la Reina Formation, ranging from Upper Barremian to Lower Aptian. The new ornithopod described here is slender and one of the smallest ever reported. An up-to-date phylogenetic analysis recovers this taxon as a basal iguanodontian. Its unique combination of characters makes it more derived than slender ornithopods like Hyphilophodon and Gasparinisaura, and bring very interesting insights into the basal iguanodontian phylogeny. Though possessing a minimum of three premaxillary teeth, this taxon also bears an extensor ilio-tibialis groove on the distal part of its femur. Moreover, its dentary and maxillary teeth are unique, remarkably similar to those regarded as having a “rhabdomorphan” affinity. This unknown taxon is suggested to be a stem taxon within Rhabdodontidae, a successful clade of basal iguanodonts from the Late Cretaceous of Europe. The Gondwanan ornithopods share the strongest affinities with this family, and we confirm Muttaburrasaurus as a sister taxon of the Rhabdodontidae within a newly defined clade, the Rhabdodontomorpha. 000056735 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/CGL2014-53548-P 000056735 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000056735 590__ $$a2.806$$b2016 000056735 591__ $$aMULTIDISCIPLINARY SCIENCES$$b15 / 63 = 0.238$$c2016$$dQ1$$eT1 000056735 592__ $$a1.236$$b2016 000056735 593__ $$aAgricultural and Biological Sciences (miscellaneous)$$c2016$$dQ1 000056735 593__ $$aMedicine (miscellaneous)$$c2016$$dQ1 000056735 593__ $$aBiochemistry, Genetics and Molecular Biology (miscellaneous)$$c2016$$dQ1 000056735 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000056735 700__ $$aTortosa, T. 000056735 700__ $$aFernández-Balador, F.T. 000056735 700__ $$0(orcid)0000-0003-1732-9155$$aCanudo, J.I.$$uUniversidad de Zaragoza 000056735 700__ $$aDíaz-Martínez, I. 000056735 7102_ $$12000$$2655$$aUniversidad de Zaragoza$$bDpto.
