Gideonmantellia is an

ornithopod dinosaur known from the Early Cretaceous (Barremian stage) Camarillas Formation of Galve, Province of Teruel, Spain. It contains a single species, Gideonmantellia amosanjuanae.[1]

Discovery and naming

In 1982, amateur palaeontologist José María Herrero Marzo together with his son Jesús uncovered in a loam pit near

nomen ex dissertatione this name was as yet invalid though.[6]

In 2012, the type species Gideonmantellia amosanjuanae was validly named and redescribed by Ruiz-Omeñaca, José Ignacio Canudo, Gloria Cuenca-Bescós, Penélope Cruzado-Caballero, José Manuel Gasca and Miguel Moreno-Azanza. The generic name honours the first describer of Hypsilophodon, Gideon Mantell. The specific name honours the late palaeontologist Olga María Amo Sanjuán, who studied the Cretaceous Galve fauna.[1]

The

neural arches, six chevrons, rib fragments, ossified tendons, the left pelvis and both hindlimbs. The specimen is part of the collection of the Museo Paleontológico de Galve
and displayed in the palaeontological hall of the townhall of Galve.

Phylogeny

The taxon was in 1995 and 2001 assigned to the

paraphyletic group and Gideonmantellia was in 2012 placed in a relatively basal position in the group Ornithopoda. More recently, a 2017 study by Madzia et al. describing the genus Burianosaurus found Gideonmantellia to be the most basal ornithopod. The cladogram is reproduced below:[7]
