Abstract:
ABSTRACTA new taxon of probable early gymnosperms is described from permineralised specimens showing excellent preservation of the tissues, from the late Lower Carboniferous (Dinantian), Brigantian, deposits of the Midland Valley of Scotland. Stanwoodia gen. nov., represented by the single species S. kirktonensis sp. nov., shows the combination of a primitive protostelic organisation with a dense secondary wood. It closely compares to the enigmatic genus Bilignea which was formerly referred with some reservations to the Cordaitales. Another interest of the new plant concerns the excellent preservation of the phloem with at least three different types of constituent cells including fibres. Stanwoodia also exhibits the oldest well-documented evidence of a sequent periderm or rhytidome in fossil plants.

Abstract:
A tafoflora da mina do Faxinal (Formação Rio Bonito, Bacia do Paraná, RS) constitui-se em uma orictocenose preservada sob forma de compressões carbonificadas em um nível de “tonstein” intermediário a uma camada de carvão. Na associação evidencia-se o nítido predomínio de fragmentos foliares de Glossopteridales (78%) em relação aos demais elementos (Cordaitales, Pteridophylla). As análises epidérmicas e morfográficas das formas relacionadas a Glossopteridales revelaram uma associação muito homogênea, permitindo a identificação de três agrupamentos taxonômicos, definidos em nível de espécie: Glossopteris papillosa sp. nov., Glossopteris similis intermittens sp. nov., Glossopteris brasiliensis sp. nov. A semelhança nos padrões encontrados leva a sugerir que este grupamento estaria vinculado, talvez em nível de família, adaptado a nicho ecologicamente restrito dentro do espectro higrófilo-mesófilo.

Abstract:
Fossil cuticles were extracted from leaves attributed to Cordaites principalis (Germar) Geinitz (Cordaitales) that were collected from Upper Carboniferous strata in Nova Scotia (Sydney and Stellarton sub-basins) and in Newfoundland (Bay St. George sub-basin). The quality of the cuticular preservation is directly related to the thermal maturity and the grain size and angularity of sediments entombing the fossil leaves. Detailed transmitted light and scanning electron microscopy of the cuticles revealed that five distinct cuticular morphotypes could be recognized, demonstrating the variability in epidermal morphology of leaves belonging to one taxon. Two morphotypes show dissimilar and discrete epidermal characteristics, whereas three morphotypes form, more or less, a morphological continuum. Comparison with cuticles from Euramerican and Angaran floral provinces suggests that only one morphotype is in common with cuticles described from Europe, while four morphotypes are new for the Carboniferous.Key words: cuticle, Cordaites, Carboniferous, Canada.

Abstract:
The Aquidauana Formation is a Permo-Carboniferous sedimentary unit, widely stratigraphicaly distributed in the northwestern and northern portions of the Paraná Basin. However, little paleontological data is available from this formation, preventing accurate biostratigraphic and paleoecological interpretations. An abundant, diversified and well preserved assemblage of palynomorphs was recognized from sampling conducted in an outcrop section in Cipolândia District of Aquidauana Municipality, state of Mato Grosso do Sul, Brazil. A total of 35 indigenous palynomorph taxa was recognized, comprising 6 species of spores (related to 5 genera), 28 species of pollen grains (14 genera) and 1 species of chlorophycean algae. Monosaccate pollen grains are exceptionally dominant, representing 90.38% of the association, particularly constituted by species of the genera Cannanoropollis (30.41% of the total assemblage), Potonieisporites (28.14%) and Plicatipollenites (19.52%). This quantitative overrepresentation is not usual from Gondwana deposits, revealing a particular plant dominance of Cordaitales in the terrestrial flora. These results are interpreted as an upland ecology characterized by plants with a moisture-independent reproduction strategy, under a glacial climate influence. Certain species of pollen allow assignment of this assemblage to the Crucisaccites monoletus Zone (Late Pennsylvanian), which had been recognized only in the middle portion of the Itararé Group at the northeastern margin of the basin.

Abstract:
A flora do Paleozóico Superior da Província Gondvânica encontra-se dividida em dois grupos principais, de acordo com sua posição taxonômica, um característico do Carbonífero Superior e outro típico do Permiano. O primeiro era composto por licópsidas, pteridospermas, cordaitales e ginkgoales, e o segundo tinha Glossopteris Brongniart constituindo o gênero mais típico, além de ser composto por muitas espécies bastante diferenciadas ecologicamente. Esta flora encontra-se hoje representada no registro fossilífero por folhas e órgãos reprodutivos preservados por impressão / compressão carbonosa e por lenhos permineralizados. Estes têm sido descritos desde meados do século dezenove principalmente como Dadoxylon Endlicher e Araucarioxylon Kraus. Entretanto, desde suas definições originais, pouco precisas, estes nomesgenéricos têm sido aplicados indiscriminadamente para diferentes tipos lenhosos, transformando- se em verdadeiro complexo taxonômico, englobando formas não necessariamente relacionáveis entre si. Na primeira parte desta reavaliação taxonômica serão analisadas as espécies de Dadoxylon com base nas novas propostas estabelecidas por diferentes autores e nas regras do CINB (Código Internacional de Nomenclatura Botânica). Como resultado do presente estudo, das 20 espécies identificadas na literatura, três foram recombinadas no gênero Dammudoxylon (Maheshwari) Maheshwari: Dammudoxylon arberi, D. waltonii e D. sp. (D. australe?); nove foram consideradas inválidas: Dadoxylon cf. D. indicum, D. cf. Eristophyton, D. kumarpurensis, D. sp. Arber, D. sp. Walton, D. sp. Moonje, D. sp. Jacob, D. sp. Narasimhan e D. sp. Seward; cinco não foram passíveis de transferência devido a ausência de características diagnósticas preservadas:Dadoxylon angustum, D. binneyi, D. brisbanense, D. maitlandi e D. williamsoni; e três necessitam ser enquadradas em novos gêneros: Dadoxylon butiense, D. sudanense e D. tordoxyloïdes.

Abstract:
The late Paleozoic deposits of the Czech Republic are famous for their rich occurence of silicified stems. Despite the fact they have been often described and are well-known among scientists and collectors, their modern evaluation is lacking. This work summarizes results of recent anatomical and paleoenvironmental studies of silicified stems of the Intra Sudetic and Krkonoše Piedmont basins, where are these fossils found very frequently. Based on field research and review of public and private collections, the presence of silicified remnants was proved in several stratigraphic units. Firstly, this work deals with silicified stems of calamitaleans, which are known from the Ploužnice Horizon of the Krkonoše Piedmont Basin, and some gymnosperms. Based on anatomical studies of the secondary xylem and other related features there were found two species of calamitaleans: Arthropitys cf. bistriata and Calamitea striata. Secondly, the more abundant Agathoxylon - type of wood was divided into two groups, which are assigned to cordaitaleans, and conifers. The palaeoenvironmental conditions were partly reconstructed according to sedimentary structures and also according to cordaitaleans - conifers ratio in each wood-bearing layer.
