Record of the genus Lycopodites in the Lower Permian of Paraná Basin, Brazil.
The genus Lycopodites, which encompasses the herbaceous forms of the lycopsids, presents broad time and spacial distribution during the Paleozoic in the Northern Hemisphere, with its initial records dating from the European Devonian. As to Gondwanan Paleozoic, to this moment, only Lycopodites amazonica Dolianiti had been reported for the Amazonian Middle Devonian (Curuá Group). Thus, the specim...
متن کاملDispersal syndromes of fossil seeds from the Lower Permian of Paraná Basin, Rio Grande do Sul, Brazil.
The morphological analysis of seeds has been an important subject in modern ecological studies, once it provides evidence about the biology and adaptations of the parent plant. However, this kind of study has been restricted to the ecology of modern plants and is rarely used in interpretations of Paleozoic data. From the understanding of dispersal syndromes analysis as an important tool to pale...
متن کاملDepositional History of the Atokan Succession (lower Pennsylvanian) in the Permian Basin
Atokan-age units in the Permian Basin record a 2-order transgression, with aerially restricted, lower Atokan fluvial to shallow-marine siliciclastics followed by pervasive carbonate deposition. In general, Atokan-age siliciclastics dominated deposition in the west of the Permian Basin while carbonate deposition dominated throughout the rest of the basin. Predominance of carbonate facies across ...
متن کاملDepositional History of the Morrowan Succession (lower Pennsylvanian) in the Permian Basin
Morrowan-age units in the Permian Basin appear to show a “second-order” transgression from siliciclastic fluvial-deltaic to shallow-marine and subsequently to carbonate deposition. In general, Morrowan-age siliciclastics dominate deposition in the west of the Permian Basin, while carbonate deposition dominates in the east. The predominance of carbonate facies in the east is due to a lack of sil...
متن کاملA 7diapsid (reptilia) Parietal from the Lower Permian of Oklahoma
A single isolated parietal bone from the Fort Sill deposit of Oklahoma is described. It has a well-developed upper temporal opening, resembling that of the primitive South African diapsids. The parietal is compared with that of Araeoscelis and Youngopsis. Based on comparison with this parietal and the configuration of the rear skull table of millerosaurs and romeriids, the bone usually identifi...
