Seven dinosaur articles in the last issue of the Spanish journal Geogaceta

Four in Spanish and three in English:

Royo Torres, R., L. Mampel & L. Alcala. 2013. Icnitas de dinosaurios
del yacimiento San Cristobal 3 de la Formacion Camarillas en Galve
(Teruel, Espana). Geogaceta, 53: 5-8.

[Dinosaur footprints of the San Cristobal 3 tracksite from Camarillas
Formation in Galve (Teruel, Spain)]

ABSTRACT: San Cristobal 3 tracksite was located in the Camarillas
Formation (early Barremian) in Galve (Teruel). As a result of being
endangered by mining, a palaeontological action was carried out by
Fundacion Conjunto Paleontologico de Teruel-Dinopolis. It was promoted
by SIBELCO Hispania and supervised by the Direccion General de
Patrimonio Cultural-Aragon Government - to safeguard the scientific
information and the most representative footprints. To fulfill that
aim, in addition to the recovery of tracks, a detailed cast and a 3D
scanning have been made. For research purposes, the tracksite was
excavated again with the result that 43 rounded tracks have been
documented until present. Nevertheless, some of them show imprints
with three digits and a rounded heel. These new data lead us to
reinterpret the trackmakers, which could not be sauropod as previously
published, but probably ornithopod dinosaurs.

evidencia de dinosaurios ornitopodos en la base de la Formacion
Huincul (Cenomaniense Superior-Turoniense, Cuenca Neuquina,
Argentina). Geogaceta, 53: 9-12.

[First evidence of ornithopod dinosaurs at the base of Huincul
Formation (Cenomanian-Upper Turonian, Neuquen Basin, Argentina)]

ABSTRACT: We describe for the first time the presence of ornithopod
dinosaurs at the base of the Huincul Formation (Cenomanian-Turonian)
of Agrio del Medio (Neuquen, Patagonia, Argentina). The specimen in
question is a well-preserved and small phalanx toenail. It presents a
general morphology in the form of a claw, similar to that of basal
ornithopods that have been found in the Upper Cretaceous of South
America. This differentiates it from the most derived iguanodontians,
which have a hoof-shaped nail. This finding is new evidence than
indicates that small basal ornithopods were in the Neuquen Basin at
least since the transition of the Early-Late Cretaceous.

morfologia del pie en sauropodos en el grupo Urbion de la Cuenca de
Cameros (Cretacico Inferior, Soria, Espana). Geogaceta, 53: 13-16.

[First evidence on the sauropod pedal morphology in the Urbion Group
from the Lower Cretaceous of the Cameros Basin (Soria, Spain)]

ABSTRACT: A sauropod footprint showing novel anatomical characters was
discovered within the Urbion Group (Barremian-Aptian) and it is here
described. It is located in the El Majadal tracksite. The footprint is
characterized by five digit marks oriented anteriorly (I),
anterolaterally (II-III) and laterally (IV-V). The claw marks can only
be recognized in digits I, II and III. As yet, the anterior
orientation of digit I is a character that has not been described in
any ichnotaxon from the  arly Cretaceous. The footprint also shows a
lateral indentation similar to that of Brontopodus birdi from the
Aptian-Albian of the USA. Taking into account the age, the skeletal
record and the similar features between the footprint and a sauropod
trackway from the same tracksite, the Titanosauriformes could be the
best candidates to have produced the sauropod footprints from this

Cobos, A. & F. Gasco. 2013. New vertebral remains of the stegosaurian
dinosaur Dacentrurus from Riodeva (Teruel, Spain). Geogaceta, 53,

ABSTRACT: The discovery of new stegosaurian remains from a site in
Riodeva (Teruel, Spain) included in the Villar del Arzobispo Formation
evidences the strong presence of these plated dinosaurs in the
Jurassic-Cretaceous transition of the Iberian Range -specifically in
the tidal and supratidal systems which gave birth to this
lithostratigraphic unit. These fossils, which consist of four
vertebral centra, are attributed to Dacentrurus armatus.Their
abundance can prove that the slight variations which can be seen among
different individuals -sometimes between specimens really close
geographically and temporally- actually correspond to intraspecific
variation of this taxon.

el yacimiento de Santa Barbara. Geogaceta, 53: 21-24

[New contributions to ichnological studies from Galve (Teruel, Spain).
Big ornithopod footprints at the Santa Barbara site]

ABSTRACT: We describe five large ornithopod natural casts found in
Galve (Teruel, Spain) during an exploration campaign. Some of these
ornithopod footprints are the largest of the Lower Cretaceous in the
east of the Iberian Peninsula. The casts support that there were big
ornithopods in the Galve Basin during the Barremian age. The
footprints, wich also provide information on the movement of the foot
during the gait, are attributed to cf. Iguanodontipus. It is the
second time that this type of track cites in the Teruel province.

First dinosaur tracks from the Lower Cretaceous of the Western High
Atlas (Morocco). Geogaceta, 53, 33-36.

ABSTRACT: Eight vertebrate trackways were found near the Imi-n-Tanout
village, in the proximity of the two Marrakesh-Agadir roads: three
theropod, two sauropods trackways; and three of an unknown bipedal
trackmaker. The outcrop is the first Early Cretaceous dinosaur
tracksite found in Morocco and the second (Barremian-early Aptian)
site of Africa. This preliminary report provides morphometric and
biomorphic descriptions of the footprints and trackways, their
classification, and an interpretation on the formation of the two
“pes-only” sauropod trackways.

Garcia-Ramos. 2013. First evidence of stegosaurs (Dinosauria:
Thyreophora) in the Vega Formation, Kimmeridgian, Asturias, N Spain.
Geogaceta, 53: 37-40.

ABSTRACT: We describe a dinosaur caudal centrum from an outcrop of the
Vega Formation (Kimmeridgian) in Colunga (Asturias Principality,
Northern Spain). It is very similar to the centra of mid-caudal
vertebrae of some stegosaurs, like Dacentrurus and Stegosaurus, which
are characterized by the presence of well developed haemal processes
on the posteroventral corner. Because this character is not diagnostic
to the generic level, the vertebral centrum is assigned to Stegosauria
indet. This is the first evidence of stegosaurs in this geological
