Jurassic deposits are discovered in the Shahreza area, southwest of Isfahan city, central Iran. They yield plant macrofossils belonging to 22 species assigned to 17 genera of various orders such as Equisetales, Filicales, Bennettitales, Cycadales, Ginkgoales and Coniferales. According to the occurrence of Annulariopsis simpsonii, Coniopteris hymenophylloides, Cladophlebis aktashensis, Nilssonia...

New evidence is presented on the Triassic–Jurassic boundary in northern Lusitanian Basin, Portugal, based miospore assemblages from a composite Upper Triassic to Lower Jurassic succession of Silves Group. The latter comprises, base top, Conraria, Penela, Castelo Viegas and Pereiros formations. Three informal palynological zones have been documented compared with coeval palynozones West South Eu...

Palynological investigations have been carried out on samples from the Upper Devonian Hongguleleng Formation of Western Junggar, Xinjiang, NW China. In total, 26 miospore species belonging to 19 genera and 28 acritarch assigned recognized lower member Fm. in Bulongguoer section. The palynofloral assemblages, particular taxa, are similar those eastern European early Famennian Corbulispora vimine...

A Mississippian miospore assemblage has been recorded from well A in the Persian Gulf in Iranian offshore, for the first time. Fifteen species of spores have been recognized in the Early Carboniferous assemblage of this well which the most important of them are: Spelaeotriletes arenaceus, Aratrisporites saharaensis, Spelaeotriletes balteatus, Spelaeotriletes triangulus and Radiizonates arcuatus...

The depositional succession of the Ponta Grossa Formation (Paraná Basin) corresponds to a wave-dominated shallow-marine environment, represented by four coarsening-upwards cycles, limited flooding surfaces. Previous studies on well-preserved and diverse assemblage miospores indicated late Pragian possibly middle Emsian age. palynological analysis Jaciara section is completed herein with marine ...

Accurate palyno-analysis by S. Loboziak (from 1980 to 1983) of 28 samples from the Upper Givetian Middle Frasnian Blacourt, Beaulieu and Ferques Formations 44 Lower Famennian Hydrequent Formation are re-evaluated. Chelinospora concinna, Verrucosisporites bulliferus, Cirratriradites jekhowskyi, Lophozonotriletes media first occurrences major criteria for Frasnian, well calibrated conodonts. Cymb...
