Comptes Rendus Palevol (advance online publication)

A tall-spined ornithopod dinosaur from the Pinilla de los Moros Formation
(Upper Hauterivian-Lower Barremian) of Salas de los Infantes (Burgos,
Spain) is described. The material consists of seven associated axial
remains, including five middle dorsal vertebrae, a fragmentary neural spine
and a dorsal rib, from a single medium-sized individual. This material was
previously referred to Iguanodon cf. fittoni. It is characterised by having
a high dorsal neurapophysis that is approximately 4.5 times the height of
the centrum. The elongation and vertical orientation of the dorsal neural
spines allow it to be distinguished from other ornithopods from the Wealden
of Europe, including Hypselospinus and Barilium from the Valanginian, and
Iguanodon and Mantellisaurus from the Barremian-Aptian. The material is
here referred to Iguanodontia indet. because it is so incomplete, but it is
potentially a distinct taxon. Among the ornithopods, only Ouranosaurus and
the hadrosaurid Hypacrosaurus possess higher dorsal neural spines.
