Jiangxititan ganzhouensis gen. et sp. nov. is a new titanosaurian sauropod recovered from the Upper Cretaceous(Maastrichtian) Nanxiong Formation of Jiangxi Province, southern China. It is characterised by:(1) posterior cervical and anterior dorsal centra strongly compressed dorsoventrally;(2) accessory horizontal laminae present within the anterior dorsal pleurocoels;(3) posterior cervical and anterior dorsal neural arches low;(4) posterior cervical and anterior dorsal neural spines deeply bifurcated and widely separated;(5) inverted'V'lamina formed by the left and right medial spinoprezygapophyseal laminae present at the anterior margin of the bifid point in posteriormost cervical and anteriormost dorsal neural spines;(6) triangular fossa formed by the metapophysis, medial and lateral spinoprezygapophyseal laminae present at the anterior margins of the posteriormost cervical and anteriormost dorsal neural spines;(7) postzygapophyses in the posterior cervical vertebrae fan-shaped;(8) medial and lateral spinopostzygapophyseal laminae present in the anterior dorsal vertebrae and;(9) anterior dorsal rib short and gracile. Our phylogenetic analysis places Jiangxititan within the deeply-nested titanosauriform clade Lognkosauria and the sympatric Gannansaurus in a much earlier-diverging lineage. This new discovery thus demonstrates the presence of both early-diverging and late-diverging titanosauriform sauropods in the Late Cretaceous Ganzhou dinosaur fauna.

Molecular biological research on Foraminifera

引用

Progress in Natural Science:Materials International 2005年第8期15卷 673-677页

作者： Kemal Topac ERTAN,Christoph HEMLEBEN Institute and museum of Geology and paleontology University of Tuebingen D-72076 Tuebingen Germany Institute and museum of Geology and paleontology University of Tuebingen D-72076 Tuebingen Germany

As one of the most important groups in micropaleontology, Foraminifera is traditionally described to have a membranous, agglutinated or carbonate shell according to its morphology, which resembles the marine granuloreticuloseans. However, recent molecular analyses on its ribosomal RNA gene have disclosed the existence of the naked, and also freshwater and terrestrial species. Foraminiferal SSU rDNA sequence suggests that this group is positioned at the base of the Eukaryotes phylogenetic trees, between Euglenoida and Diplomonadida. Existence of a large amount of genetic types in planktonic foraminifera suggests an underestimation of the biodiversity for the nearly 50 species in world oceans and their close relationship with the ocean environment, such as bio-geographic distribution and water currents. This provides a more reliable proxy for future paleoenvironmental study.
