Biodiversity and taxonomy of punctoid micromollusks from southern Brazil, with description of a new species of Radiodiscus from the «Mata Atlántica» (Atlantic Rain Forest) (Mollusca, Gastropoda, Pulmonata). Species in Charopidae and Punctidae from the «Centro de Pesquisas e Conservação da Natureza Pró-Mata (CPCN Pró-Mata)» (Brazil, Rio Grande do Sul) and Thiele's collection are studied. The native species Rotadiscus amancaezensis (Hidalgo, 1869), Radiodiscus cuprinus Fonseca & Thomé, 2000, R. compactus (Suter, 1900) comb. nov., R. promatensis Miquel, Ramírez & Thomé, 2004, Lilloiconcha superba (Thiele, 1927, L. zulmae Miquel, Ramírez & Thomé, 2004 comb. nov., L. gordurasensis (Thiele, 1927, and Radioconus pleurophorus (Moricand, 1846) comb. nov., and the probably exotic, Sinployea? goeldii (Thiele, 1927) were present in the charopid samples from the CPCN Pró-Mata; punctids were represented by Paralaoma servilis (Shuttleworth, 1852) and Paralaoma sp. A new species of Charopidae is described: Radiodiscus sanchicoensis sp. nov. It is a tiny shell with 75 to 60 axial ribs in the last whorl. The protoconch microsculpture of Lilloiconcha, Zilchogyra and Radioconus, with generic value, is studied, as well as their internal calcareous teeth. Several species and a genus (Lilloiconcha = Trochogyra) are places into synonymy. The actual presence of some Patagonian species in southern Brazil is discussed; the only charopid reported to be present in Patagonia and Brazil is R. amancaezensis. R. sanchicoensis is the dominant species in the CPCN Pró-Mata, followed by R. cuprinus.

This study focuses on the three-dimensional (3D) reconstruction of an Late Jurassic fossil forest based on a fossil assemblage located in the Shishugou Formation near Jiangjunmiao, north-eastern Junggar Basin, Xinjiang Uygur Autonomous Region, Northwest China. On the basis of tree stumps found in growth position together with published data on megaplant fossils, seeds and spores, a highresolution digital computer model, including different forest layers, was developed. In a study area of 31,500 m², 65 tree stumps with diameters between 0.2 and 2.9 m were mapped and subsequently used for the 3D reconstruction. The forest grew under moist conditions, probably close to the banks of an anastomosing river and consisted primarily of conifers, in particular Araucariaceae. Even though the tree density of the forest is only 22 trees/ha, the 3D reconstruction indicates a relatively closed canopy. Megaplant fossils and spores also show evidence for the presence of Angiopteris, Osmunda and Coniopteris, which were then used to reconstruct the understory of the forest. The trees were modelled in three different growth stages, representing young, older and mature trees, respectively. The growth parameters of individual trees and ferns were randomized in order to avoid duplications within the reconstruction. Detailed textures of leaves, fronds and bark were created to give the plants a more realistic appearance than that in previously published 3D reconstructions of fossil forest assemblages. Estimations of net biomass (approximately 9 tons/ha), annual biomass production and a calculation of nearest neighbour index (0.86) suggest an open forest with spatially distributed trees.
