It appears 2006 isn't done with us yet...!
First, from Spain:
Pérez-Lorente, F., Hadri, M., and Boutakiout, M. 2006. Primeras icnitas de
dinosaurio en sur del Alto Atlas Central. Carixiense (Formación de Arhbalou.
Goulmima. Marruecos). Geogaceta 40:159-162.
ABSTRACT: The first found tracks of dinosaur in the North of the
Goulmima-Tinerhir line (Inner Haut Atlas Central, Morocco) are described.
They are located in the Arhbalou Formation and come from isolated and
grouped prints mainly of theropod dinosaur. They have importance by the
enlargement of the geographical area with dinosaur paleoichnological sites
and by they constitute the first dated Carixian dinosaur footprints founds
Pérez-Lorente, F., Guillén-Mondéjar, F., and del Ramo, A. 2006. Primeras
icnitas de dinosaurio en Murcia (Albiense de Yecla). Geogaceta 39:147-150.
ABSTRACT: The first found tracks of dinosaur in Murcia are described. They
are in the formation Utrillas of Yecla and come from herds of sauropod
dinosaur. In spite of the bad conservation, they have importance by the
shortage of tracks in Spain of Albian and because they open the possibility
for future campaigns of surface survey.
Then, from Brazil:
Medeiros, M.A. 2006. Large theropod teeth from the Eocenomanian of
northeastern Brazil and the occurrence of Spinosauridae. Revista Brasileira
de Paleontologia 9(3):333-338.
ABSTRACT: Theropoda teeth can show sufficiently distinct features to be, in
some cases, considered as confident diagnostic material. In this work, 275
complete or fragmentary teeth, collected at the Laje do Coringa site
(Alcântara Formation), have been analyzed. In some of them, the typical
spinosaurine morphology is present while in others an intriguing morphology
was observed: teeth combining typical features of spinosaurines (smooth
carinae with wrinkles on its base) with other characters as absolutely
smooth enamel and basal cross section gently compressed labio-lingually.
These different forms typify two morphotypes; a number of other teeth
present variation that links them by a morphologic gradient. Morphotype 1
records the presence of spinosaurine dinosaurs in the Eocenomanian of
northeastern Brazil and morphotype 2 may represent a new species of
Theropoda, unknown by skeletal remains, and perhaps closely related to the
spinosaurine form recorded.
Gallo de França, M.A., and Langer, M.C. 2006. Phylogenetic relationships of
the Bauru Group turtles (Late Cretaceous of south-central Brazil). Revista
Brasileira de Paleontologia 9(3):365-373.
ABSTRACT: No chelonian of the Bauru Group (Late Cretaceous of south-central
Brazil) has so far been included in a numerical cladistic analysis with an
explicit taxon-character data matrix. Out of the five taxa formally
described from that stratigraphic unit, those based on more complete
specimens - Bauruemys elegans, Cambaremys langertoni, and Roxochelys
wanderleyi - were considered in a cladistic study of the pro-Podocnemidae
Pelomedusoides. The resulting hypothesis of relationships places the
specimen known as FR-4922 and Brasilemys josai among Pelomedusoides basal to
Podocnemoidea. Within that clade, the Bauru Group taxa lie basal to
Podocnemidae. Roxochelys is revealed to be a monophyletic genus, closer to
Podocnemidae than the other analyzed Cretaceous forms. Among these,
Bauruemys elegans is more derived than Portezueloemys patagonica, while the
position of Cambaremys langertoni is ambiguous. Within extant Podocnemidae,
a sister group relationship between Peltocephalus dumerilianus and
Erymnochelys madagascariensis is proposed.
Brandalise de Andrade, M., Bertini, R.J., and Piacentini Pinheiro, A.E.
2006. Observations on the palate and choanae structures in Mesoeucrocodylia
(Archosauria, Crocodylomorpha): phylogenetic implications. Revista
Brasileira de Paleontologia 9(3):323-332.
ABSTRACT: The palate and choanae structures are important to the study of
the evolution in Crocodylomorpha. Notosuchians, sebecosuchians and other
Mesoeucrocodylia show a considerable diversity of patterns. Some
notosuchians (Mariliasuchus, Notosuchus, Sphagesaurus) possess important
similarities with at least one sebecosuchian (Stratiotosuchus), especially
the triangular-subtriangular choanae, and the exclusion of the pterygoid
from the posterior border of the suborbital fenestra. The use of these
characteristics may represent useful information in phylogenetic analysis
and should always be described in detail.
Bertini, R.J. 2006. Taphonomy and depositional history of an Upper
Cretaceous turtle-bearing outcrop from the Adamantina Formation,
southwestern São Paulo State. Revista Brasileira de Paleontologia
ABSTRACT: The Adamantina Formation deposits (Upper Cretaceous) from the
Bauru Basin, in southwestern São Paulo State, have revealed an extraordinary
and well preserved assemblage of fossil turtles. In this contribution some
new unique findings from these deposits and the Bauru Basin, are reported
and discussed. Additionally, some peculiar sedimentary structures, as a bone
fragment crossing two sedimentary layers, associated with the fossils, are
described and biostratinomic considerations regarding these materials are
made. The turtle remains from the studied outcrop have undergone short
subaerial exposure and transport, being quickly buried. It was also verified
that the time elapsed between these sedimentary episodes, in one of the
samples, was almost instantaneous.
Lastly, two brand-new papers I don't have yet:
Averianov, A.O. 2007. Mid-Cretaceous ornithocheirids (Pterosauria,
Ornithocheiridae) from Russia and Uzbekistan. Paleontological Journal 41(1):
Christian, A. and Dzemski, G. 2007. Reconstruction of the cervical skeleton
posture of Brachiosaurus brancai Janensch, 1914 by an analysis of the
intervertebral stress along the neck and a comparison with the results of
different approaches. Fossil Record 10(1): 38-49.
