Here a few new refs that may not have been mentioned here

New Archosaurs from the Jurassic of Siberia and Mongolia. 
Paleonotological Journal 37 (1): 53-57.
Abstract-New finds of crocodiles and dinosaurs from the 
Late Jurassic deposits of southwestern Mongolia 
(Shar-Teg locality) and Eastern Siberia (basin of the 
Vilyui River, Teete locality) are described. A new species 
of small-sized running crocodiles, Nominosuchus arcanus, 
characterized by a small number of teeth is 
described from the Shar-Teg locality on the basis of the 
anterior parts of the skull. A Jurassic assemblage of 
dinosaurs, including Stegosaurus sp., sauropods resembling 
Camarasaurus, and predatory theropods, includ-
ing Allosaurus sp., is established for the first time on 
the basis of the material from the Teete locality in 
Siberia. 
This corroborates the presence of the zoogeographic 
relationship between the North American and Siberian fau-
nas at that time.

of a Primitive Hadrosauroid Dinosaur (Ornithischia, 
Hadrosauroidea) in the Cretaceous of the Belgorod Region. 
Paleonotological Journal 37 (1): 58-61.
Abstract-An isolated maxillary tooth and opisthocoelous 
anterior thoracic or posterior cervical vertebral cen-
trum of a duck-billed dinosaur, Hadrosauroidea indet., are 
described. These parts originate from the marine 
Albian-Cenomanian deposits of the Stoilo iron ore quarry 
near the town of Staryi Oskol, Belgorod Region. This 
is the oldest record of a hadrosauroid dinosaur in Eastern 
Europe and one of the oldest representatives of this 
group in the world.

The year date on the new Historical Biology is "2001" but  
the website did not post the articles until 2003 so the 
exact publication date is still unclear to me--I'm 
guessing 2003.

The Caribou Migration Model for Arctic Hadrosaurs 
(Dinosauria: Ornithischia): A Reassessment . Historical 
Biology: A Journal of Paleobiology 15 (4): 323 - 334. 
The recovery of abundant dinosaur fossils from high 
paleolatitudes of northern Alaska has raised some hard 
questions in relation to any available model of dinosaur 
physiology. To explain the occurrence of hadrosaurs at 
high ancient latitudes, a model involving long-distance 
migration analogous to that of the modern caribou has been 
proposed. The model calls for seasonal movements over 
great latitudinal distances by these Cretaceous 
hadrosaurs. This model is reassessed in terms of the 
growth, body sizes, and inferred physiological ecology of 
the hadrosaurs and the caribou. Histological data suggest 
that juvenile hadrosaurs obtained from northern Alaska 
were greater than 1 year in age. Comparison of the 
relative sizes of juvenile and adult hadrosaurs with 
juvenile and adult caribou suggests, based on qualitative 
energetics, that the juvenile hadrosaurs were too small to 
participate in long-distance migration. The "hadrosaurs as 
caribou" model provides clues to the feeding ecology of 
North Slope hadrosaurs, if they are reinterpreted as year-
round residents of high latitudes. However, it does not 
constitute a satisfactory basis on which to infer long-
distance seasonal migrations by these animals.

Maisch, Michael W. & Axel Hungerbühler, 2003? (2001). New 
Evidence for a Discrete Supratemporal Bone in the Jurassic 
Ichthyosaur Temnodontosaurus. Historical Biology: A 
Journal of Paleobiology 15 (4): 335 - 345. 
Abstract:  The temporal region in Temnodontosaurus 
trigonodon and Temnodontosaurus platyodon consists of 
three discrete ossifications. These bones are identified 
as the supratemporal, bordering much of the temporal 
opening, and in mid-cheek, the squamosal, which is in 
contact with the quadratojugal along its ventral margin. 
Interpretation of the bone in mid-cheek position as a 
neomorphic "supernumerary" ossification is rejected. The 
supratemporal bone of ichthyosaurs is functionally 
convergent with the squamosal of diapsids. The size and 
configuration of the supratemporal casts doubt on the 
supposition that ichthyosaurs were diapsids. 

Peters, David, 2003? (2001). A New Model for the Evolution 
of the Pterosaur Wing--with a twist. Historical Biology: A 
Journal of Paleobiology 15 (4): 277 - 301. 
Abstract:  A new hypothesis for the evolution of the 
pterosaur wing is presented. It is based on the 
observation that many aspects of pterosaur non-wing 
anatomy were present in their non-volant, prolacertiform 
sister taxa. In pterosaurs alone, metacarpal IV was 
twisted 90° medially, so the wing digit flexed in the 
plane of the metacarpus, rather than towards the palm as 
in other tetrapods. While grappling a tree using manual 
digits I-III, a pre-pterosaur with this character would 
have been free to flex and extend digit IV in the plane 
tangential to the circumference of the tree. The addition 
of a small dermal extension that opened like a Japanese 
fan would essentially have completed the development of 
the proto-wing. Its subsequent increase in size was 
brought on by selective competition. Successful powered 
flight would have been possible only after a critical wing 
size had been achieved.

¿Saurópodos asiáticos en el Barremiense inferior 
(Cretácico Inferior) de España?
Ameghiniana 39(4):443-452 . 
Abstract. ASIAN SAUROPODS IN THE LOWER BARREMIAN (LOWER 
CRETACEOUS) OF SPAIN?. We describe here three sauropod 
teeth from the Lower Cretaceous (lower Barremian) of La 
Cantalera (Josa, Teruel, Spain). The teeth are spoon-
shaped with a lingual cingulum-like structure. The general 
morphology is closer to Camarasauridae, but the presence 
of cingular structure indicates a different group, more 
derived that this family. The problematic genus Euhelopus 
from the Upper Jurassic or Lower Cretaceous of China and 
some isolated teeth from the Lower Cretaceous of China, 
Russia and Mongolia are the only sauropods with similar 
teeth. We suggest the presence of a sauropod group in the 
Asian and European Early Cretaceous. This group is 
included in the family Euhelopodidae and the 
Titanosauriformes clade. This European - Asian Early 
Cretaceous geographic connection has been previously 
observed with mammals and ornithopod dinosaurs. 

CORIA,Rodolfo A.,  Philip J. CURRIE, David EBERTH and 
Alberto GARRIDO, 2002. Bird footprints from the Anacleto 
Formation (Late Cretaceous), Neuquén, Argentina. 
Ameghiniana 39(4):453-463. 
Abstract. Bird footprints recovered from the Anacleto 
Formation (Campanian, Upper Cretaceous) at Sierra Barrosa, 
northeast of Plaza Huincul, Neuquén Province, represent 
the earliest records of bird traces from Patagonia. All of 
the specimens were recovered from two sites at the same 
stratigraphic level separated by less than a hundred 
meters. They are tridactylous, clawed prints with 
divarications greater than 90° between digits II and IV, 
and seem to represent three different ichnotaxa. The most 
common avian footprint lacks hallux traces and can be 
referred to Aquatilavipes. A smaller number of the 
footprints includes distinct hallux impressions, and are 
similar to Ignotornis and Jindongornipes. The third type 
represents a new ichnotaxon, Barrosopus slobodai ichnogen. 
et ichnosp. nov. characterized by smaller size and a digit 
II impression that is separate from the conjoined third 
and fourth ones. These fossilized bird tracks are the 
first reported from the Neuquén Basin, and double the 
number of Cretaceous occurrences of avian footprints in 
Argentina.
