The first poster session was small and many posters must have been missing, as I don't recall seeing them (then again, I was pretty tired...). You may note that my details are mainly on phylogenetics, taxonomy and morphology, as those are the areas I am most interested in. Apologies to those whose talks I missed or didn't comment on due to a focus on morphometrics, taphonomy, biomechanics, ecology and other topics.
Fiorillo and Montgomery, 2001. Depositional setting and paleoecological significance of a new sauropod bonebed in the Javeline Formation (Cretaceous) of Big Bend National Park, Texas. JVP 21(3) 49A.
At least three juvenile Alamosaurus from the Javelina Formation (Maastrichtian) of Texas are reported. They are about 10-13 meters long, which is 50-60% of adult length. Remains include- cervical, vertebral centrum, sacral neural spine, sacral ribs, humerus, metacarpal, ilium, pubis, femora, ungual.
Ford, 2001. The armor of sauropods. JVP 20(3) 50A.
A good summary of sauropod armor through the ages, from Titanosaurus to Lametasaurus to Saltasaurus to Czerkas' diplodocid spines to Agustinia.
Tomida, Katsura and Tsumura, 2001. A new titanosauroid sauropod from the Early Cretaceous of Japan. JVP 21(3) 108A.
A partial skeleton from the Matsuo Group (Early Cretaceous) of Japan is described. It includes four caudals, humeri, radius, ischium, femora, tibia and fibula. Codable characters from Upchurch (1998) include the primitive- amphicoelous proximal and distal caudal centra; proximal caudal centra longer than tall; and the derived- proximal caudals with a ventral excavation bounded laterally by ridges; middle caudal centra dorsoventrally compressed in section; middle caudal neural arches placed on anterior portion of centrum; caudal transverse processes confined to less than twenty vertebrae; forelimb/hindlimb ratio more than .75 (the humerofemoral ratio is .89); straight femoral shaft; proximolateral femoral bulge; fourth trochantor on caudomedial margin of shaft; fourth trochantor reduced; femur with a transversely wide cross section. The combination of the first four characters is supposedly unique among titanosauroids, indicating a new taxon.
Other posters I read included-
Coria, Chiappe and Negro, 2001. Sauropod embryonic integument from Auca Mahuevo (Late Cretaceous), Argentina. JVP 21(3) 42A.
Leal, Kellner, Azevedo and Rosa, 2001. Taphonomic aspects of prosauropod dinosaur from the Caturrita Formation, Late Triassic, Southern Brazil. JVP 21(3) 72A.
I missed the following, if they were there.
Calvo, Porfiri, Veralli and Poblete, 2001. One of the largest titanosaurid sauropods ever found, Upper Cretaceous, Neuquen, Patagonia, Argentina. JVP 21(3) 37A.
A new titanosaurid from the Rio Neuquen Formation of Argentina is described. It is known from eight cervicals, a partial dorsal, a sacrum, two caudals, ilia, a pubis and an ischium. More material is present, to be excavated next year. A mid cervical vertebra is 1020 mm long, 1130 mm high and 520 mm wide. The sixth sacral vertebra (with rib) is 1170 mm wide, a proximal caudal is 800 mm high, the pelvis is 2800 mm wide and the pubis is 1370 mm long. Titanosaurid characters include- no dorsal hyposphene-hypantra; six sacrals; procoelous proximal caudals; anteriorly placed caudal neural arches; open haemal arches; pubis longer than ischium. Diagnostic characters include- very high dorsal(?) neural spines; sail-like in anterior view; strong prespinal laminae on proximal caudal vertebrae; proximal caudal neural spines laterally expanded at distal end.
Erickson and Hanks, 2001. A puzzling young diplodocid. JVP 21(3) 47A.
A well preserved juvenile skull from the Morrison Formation of Wyoming is described. It resembles Diplodocus except for the anteriorly narrowing snout and mandibles. This could be due to ontogeny, deformation, sexual dimorphism or taxonomic difference.
Santucci and Bertini, 2001. New titanosaurids from the Bauru Group, Continental Upper Cretaceous of Southeastern Brazil. JVP 21(3) 96A-97A.
A proximal caudal vertebra from the Uberaba Formation (Campanian-Maastrichtian) is a new taxon, based on the strong spinopostzygopophyseal and centropostzygopophyseal laminae. There are slightly procoelous proximal caudal vertebrae with pleurocoels from the Uberaba and Adamantina Formations (the latter also Campanian-Maastrichtian). A basal titanosaurian from the Adamantina Formation is represented by six proximal caudals, with pleurocoels, broad zygopophyseal articular facets and transversely expanded neural spine tips.
Tomorrow, I'll go over the first big poster session, with tons of new information.
