Thanks to Denver, Dan and Mike for sending me these papers, I now have them 
all. If anyone else wants one, feel free to contact me.

Best,
Zach

>>gregariousness in rebbachisaurids (Dinosauria, Sauropoda, Diplodocoidea) from 
>>the Early Cretaceous of Neuquén (Rayoso Formation), Patagonia, Argentina. 
>> Journal of Vertebrate Paleontology 32 (3):603-613.

>>Abstract:  For the first time an association of adult and juvenile 
>>rebbachisaurid sauropods is described. The material comes from the Early 
>>Cretaceous locality of Agrio del Medio (Neuquén, Argentina). The three 
>>specimens apparently formed a single group, and their death seems to have 
>>been almost simultaneous. The two juvenile specimens are represented by axial 
>>and appendicular bones. They show a close relationship with *Zapalasaurus 
>>bonapartei*, which comes from a different sector of the same basin, but which 
>>is approximately the same age. The discovery at Agrio del Medio suggests th
us behavior. The paleoenvironments in which rebbachisaurids are normally 
recorded implies a greater tolerance toward extremely arid environments than 
that shown by macronarian sauropods.

>>Mannion, P.D. & A. Otero, 2012. A reappraisal of the Late Cretaceous 
>>Argentinean sauropod dinosaur *Argyrosaurus superbus*, with a description of 
>>a new titanosaur genus.  Journal of Vertebrate Pa
>bus* is one of the earliest-named Argentinean dinosaurs. The holotype 
>comprises a complete forelimb, probably from the upper member of the Bajo 
>Barreal Formation (Late Cretaceous), Chubut Province. Numerous remains have 
>been referred to *Argyrosaurus* from Argentina and Uruguay; however, the type 
>specimen has not been adequately diagnosed and referrals have predominantly 
>been based upon their large size. Here we redescribe *Argyrosaurus*, 
>demonstrating it to be a valid titanosaur genus based on five autapomorphies, 
>as well as an unique character combination. The exact placement of 
>*Argyrosaurus* within Titanosauria is uncertain, although the probable 
>presence of carpal bones, otherwise unknown in titanosaurs, may indicate a 
>basal position. None of the referred remains can be attributed to 
>*Argyrosaurus*, and most should be regarded as indeterminate titanosauriforms. 
>The exception to this is a partial skeleton from the
>lower member of the Bajo Barreal Formation (early Late Cretaceous), Chubut 
>Province, comprising dorsal and caudal vertebrae, as well as numerous 
>appendicular elements. This specimen is distinct from *Argyrosaurus* and can 
>also be differentiated from other sauropods based on an unusual character 
>combination (including plesiomorphic tarsus), plus one autapomorphy. 
>*Elaltitan lilloi*, gen. et sp. nov., displays numerous titanosaur characters 
>and shares several features with derived taxa such as *Neuquensaurus*, 
>*Opisthocoelicaudia*, *Rapetosaurus*, *Saltasaurus*, and *Trigonosaurus*. 
>*Elaltitan* can be referred to Lithostrotia; however, its precise position 
>within this clade must await future phylogenetic analysis
tion of the titanosaurs *Argyrosaurus* and *Elaltitan* provides new information 
on this diverse but still poorly understood clade.

>>Abstract:  Recent studies have blurred the distinctness of two major avian 
>>groups: the Enantiornithes, a major radiation of early birds in the 
>>Cretaceous, and the Ornithuromorpha, the clade including extant birds. Here 
>>we describe a new enantiornithine bird from the Lower Cretaceous Jiufotang 
>>Formation of western Liaoning, China, *Xiangornis shenmi*, gen. et sp. nov., 
>>which further reduces the morphological gap between the two groups. 
>>*Xiangornis shenmi* has several enantiornithine features, including a furcula 
>>with a significantly elongated hypocleidium, a coracoid with a convex lateral 
>>margin, and a minor metacarpal that extends further distally than the major 
>>metacarpal. However, it also possesses some derived ornithurine features,

>>metacarpal) that is completely fused to the major metacarpal, a large 
>>extensor process on the alular metacarpal, pr
>between
>the minor and major metacarpals, and an intermetacarpal space positioned 
>significantly distal to the alular metacarpal. This new find indicates that a 
>carpometacarpal morphology similar to that seen in modern birds probably 
>evolved independently in enantiornithines and appeared earlier than in 
>Ornithuromorpha, and demonstrates that character evolution in early birds was 
>more complex than previously believed.
