The Neverending New Paper II

["Jerry D. Harris" <jharris@dixie.edu>]

In addition to Scott's undoubtedly frabjuous paper, there are several others
in what I assume must be the same volume -- these are the ones I know of,
and there may well be more!


Calvo, J.O., González-Riga, B.J., and Porfiri, J.D. 2008. A new titanosaur
sauropod from the Late Cretaceous of Neuquén, Patagonia, Argentina. Arquivos
do Museu Nacional, Rio de Janeiro 65(4):485-504.

ABSTRACT: The discovery of Muyelensaurus pecheni gen. et sp.nov., a new
slender titanosaurid, is relevant from anatomical and systematic viewpoints.
The specimens come from the Upper Cretaceous strata of the Portezuelo
Formation (Turonian-Early Coniacian) at Loma del Lindero, Rincón de los
Sauces area, Neuquén Province, Argentina. The remains include a braincase,
cervical, dorsal, sacral and caudal vertebrae, and numerous appendicular
bones. It is characterized by the following association of autapomorphies:
basal tubera diverge 70 degrees from each other; thin and concave lamina
that unit basal tubera ventrally, basioccipital condyle wider than the
proximal portion of the basal tubera; posterior dorsal neural spines with
large prespinal lamina  reinforced by two small accessory laminae, distal
end of pubic blade rectangular and medially thick. A cladistic phylogenetic
analysis placed Muyelensaurus  pecheni gen. et sp.nov. and Rinconsaurus
caudamirus in a new eutitanosaur clade named herein Rinconsauria. This new
clade include middle-sized sauropods different from Aeolosaurini,
Opisthocoelicaudiinae or Saltasaurinae taxa.


Calvo, J.O., Porfiri, J.D., and Novas, F.E. 2008. Discovery of a new
ornithopod dinosaur from the Portezuelo Formation (Upper Cretaceous),
Neuquén, Patagonia, Argentina. Arquivos do Museu Nacional, Rio de Janeiro
65(4):471-483.

ABSTRACT: We describe the postcranial skeleton of a new Cretaceous
ornithopod, Macrogryphosaurus gondwanicus gen.nov., sp.nov. from Patagonia,
Argentina. The specimen was found in the Portezuelo Formation, Neuquén
Group, Upper Cretaceous. Macrogryphosaurus gondwanicus gen.nov., sp.nov. is
diagnosed by having triradiate sternum with the anterior border tribranched,
two laterally placed and outwardly directed, and one centrally placed,
smaller, and forwardly directed. Sternal ribs flattened, twisted and
distally expanded. Last dorsal vertebra with well-developed hyposphene. A
thin plate-like are located in front of the sterna. Together with these
autapomorphies, this new species of ornithopod differs from Talenkauen
santacrucensis by having the pubic peduncle of ilium less developed, a more
acute angle between the anterior process of ilium and the pubic peduncle,
the acetabular cavity slightly marked. Also present ten cervical vertebrae,
fourteen dorsal vertebrae, epipophyses on the third cervical vertebra placed
over the distal end of the postzygapophyses and posteriorly projected. The
presence of plates on the lateral side of the thorax and well developed
epipophyses on the third cervical vertebra, were originally interpreted as
autapomorphies for the euiguanodontian Talenkauen santacrucensis. These
features are also present in Macrogryphosaurus gondwanicus gen.nov, sp.nov.,
and are regarded as synapomorphies defining a new clade of Euiguanodontia
dinosaurs comprising the two species: Elasmaria nov.



Calvo, J.O., Porfiri, J.D., González Riga, B.J., and Kellner, A.W.A. 2008.
Anatomy of Futalognkosaurus dukei Calvo, Porfiri, González Riga & Kellner,
2007 (Dinosauria, Titanosauridae) from the Neuquén Group (Late Cretaceous),
Patagonia, Argentina. Arquivos do Museu Nacional, Rio de Janeiro
65(4):511-526.

ABSTRACT: Titanosaurs are among the largest dinosaurs known to date. Here we
describe the anatomy of Futalognkosaurus dukei, the most complete giant
sauropod ever found. It comes from outcrops of the Portezuelo Formation at
the Barreales lake, some 90 km northwest of Neuquén city (Patagonia). The
specimen consists of a complete neck, dorsal vertebrae with ribs, pelvis,
and one caudal vertebra. Futalognkosaurus dukei is a member of the
Titanosauridae and belongs to the Lognkosauria, a clade that includes
Mendozasaurus neguyelap and probably also the giant Puertasaurus reuili.

"There's a saying that goes 'people who live in glass houses shouldn't throw
stones'... OK. How about...NOBODY should throw stones. That's crappy
behavior! My policy is 'no stone-throwing regardless of housing situation.'
There's an exception, though. If you're TRAPPED in a glass house...and you
have a stone, then throw it! What are you, an idiot? It's really 'ONLY
people in glass houses should throw stones'... provided they're trapped, in
a house... with a stone. It's a little longer, but you know..."
