You, H., and Luo, Z. 2008. Dinosaurs from the Lower Cretaceous Gongpoquan
Basin in Jiuquan Area, Gansu Province, China. Acta Geologica Sinica
82(1):139-144.

ABSTRACT: Dinosaurs from the Lower Cretaceous Xinminpu Group of the
Gongpoquan Basin in the Jiuquan area, Gansu Province, northwestern China
were mainly excavated during the course of two projects; the Sino-Japanese
Silk Road Dinosaur Expedition in 1992, and the Sino-American Mazongshan
Dinosaur Project during 1997-2000. A diverse dinosaur assemblage, including
members of Theropoda, Sauropoda, Iguanodontoidea, and Neoceratopsia, has
since been discovered. This Gongpoquan dinosaur assemblage is characterized
by the coexistence of basal representatives of the diverse clades that would
subsequently dominate the Late Cretaceous dinosaur faunas, such as two basal
neoceratopsians Archaeoceratops oshimai and Auroraceratops rugosus, the
basal hadrosauroid Equijubus normani, and the basal titanosauriform
Gobititan shenzhouensis. This assemblage is also characterized by members of
the Ornithomimosauria and Therizinosauroidea with unusually large body size
(for this geological time interval). Comparative study shows, although
closely related, all dinosaurs from the Xinminpu Group in the Gongpoquan
Basin are more derived than those from the Jehol Group in the western
Liaoning Province in their respectively clades. Considering the younger age
of the dinosaur-bearing Xinminpu Group (Albian) in the Gongpoquan Basin than
the Jehol Group in western Liaoning Province (late Hauterivian-early
Aptian), the Gongpoquan dinosaur assemblage probably represents a later,
more derived stage in the evolution of Early Cretaceous Psittacosaurus-fauna
in northern China.

Gómez, R.O., Báez, A.M., and Rougier, G.W. 2008. An anilioid snake from the
Upper Cretaceous of northern Patagonia. Cretaceous Research 29(3):481-488.
doi: 10.1016/j.cretres.2008.01.002.

ABSTRACT: We report the first record of anilioids from southern South
America, a region where they do not live today. The fossils come from the
Allen Formation (Late Campanian?Early Maastrichtian) at Bajo Trapalcó and
Bajo de Santa Rosa localities, Río Negro province, Argentina. The remains
consist of several vertebrae, most of which belong to the mid?posterior
precloacal region of the column. Comparisons to other extant and extinct
anilioid taxa indicate that these remains represent a new taxon,
Australophis anilioides gen. et sp. nov. Australophis is morphologically
closer to Palaeocene Hoffstetterella from Brazil and extant South American
Anilius than to any other snake. These taxa might be closely related, in
which case they would represent a lineage distinct from that including
Cylindrophis and uropeltids. The two lineages must have diverged by the Late
Cretaceous.




Nye, E., Feist-Burkhardt, S., Horner, D.J., Ross, A.J., and Whittaker, J.E.
2008. The palaeoenvironment associated with a partial Iguanodon skeleton
from the Upper Weald Clay (Barremian, Early Cretaceous) at Smokejacks
Brickworks (Ockley, Surrey, UK), based on palynomorphs and ostracods.
Cretaceous Research 29(3):417-444. doi: 10.1016/j.cretres.2008.01.004.

ABSTRACT: In 2001 a partial skeleton of an Iguanodon was discovered in the
Upper Weald Clay (Barremian, Early Cretaceous) at Smokejacks Brickworks near
Ockley, Surrey, UK. When the dinosaur was excavated, a detailed
stratigraphic section was logged and 25 samples taken for palynological and
micropalaeontological (ostracod and megaspore) analysis, including a
detailed sample set of the dinosaur bed itself. Qualitative and quantitative
analysis of the palynoflora revealed rich and well-preserved non-marine
assemblages of pollen and spores, including early angiosperms, and
freshwater green algae. Four types of angiosperm pollen are described and
assigned to the genus Retimonocolpites Pierce, 1961, but left in open
nomenclature. Some marine elements such as dinoflagellate cysts are
identified as the result of reworking of Middle and Upper Jurassic
sediments. The pollen/spore assemblages depict a vegetational change from
principally gymnosperm-dominated assemblages at the base to principally
pteridophyte-dominated assemblages at the top of the section. The dinosaur
bed shows a pteridophyte-dominated assemblage, with a significantly high
amount of the freshwater green alga Scenedesmus novilunaris He Cheng-quan et
al., 1992. Samples close to the dinosaur bed yielded the first useful
ostracod finds from Smokejacks Brickworks: well-preserved assemblages
containing Cypridea clavata (Anderson, 1939), Damonella cf. pygmaea
(Anderson, 1941), Stenestroemia cf. cressida Anderson, 1971 and
Stenestroemia sp. A, and fragments and damaged valves of a thin-shelled
ostracod, possibly belonging to Mantelliana Anderson, 1966. Those identified
as Cypridea clavata show a wide range of morphological variety and in
opposition to Anderson's (1967, 1985) taxonomic scheme, which would assign
them to up to five different taxa, they are considered to be intraspecific
variants of a single species. The possibilities and limitations of age
determination of the Wealden sediments using palynomorphs and ostracods are
discussed; distinct forms of early angiosperm pollen, together with the
ostracod fauna, are consistent with an early Barremian age. Pollen and
spores are discussed in terms of their parent plants and the reconstruction
of vegetation and palaeoclimate. Palynology and ostracods give evidence for
temporary freshwater conditions at the time when the Iguanodon died and the
carcase was buried.

"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..."
