Faunipollenites Bharadwaj 1962 and Protohaploxypinus Samoilovich 1953 emend. Morbey 1975: morphologic comparison of oxidized and non- oxidized specimens from India and Brazil, and its taxonomic importance

Upper Pennsylvanian Age of the Lower Talchir Formation in the Wardha Basin, Central India, Based on Guide Palynomorphs Present in Radiometrically-Dated Palynozonations in South America, Africa, and Australia

“…Samples were processed applying HCL (10%) and HF (40%), washed with distilled water, sieved through a 10 µm mesh and slides prepared with +10 residues and Canada balsam. The residues were divided in two sets and one oxidized with HNO 3 (40%) for two hours and KOH (10%) applied for 2 minutes (see di Pasquo et al, 2021). Quali-quantitative (200 palynomorphs per sample) examination performed using a Leica DM 2500 light microscope and pictures of specimens were captured with a Leica DFC290 camera using LAS V4.6 software.…”

“…Tiwari & Tripathi, 1992;Aggarwal & Jha, 2013, and their references), is required as previously highlighted in several publications (Truswell, 1980;Stephenson, 2008;Modie & Le Hérissé, 2009;di Pasquo et al, 2015di Pasquo et al, , 2021Barbolini et al, 2018). In the case of those not illustrated taxa a revision of samples of their respective works or the development of new studies to identify Pennsylvanian and Permian guide species is mandatory (see Murthy et al, 2020;di Pasquo et al, 2021). Murthy et al (2020) obtained a palynoassemblage attributed to the Potonieisporites neglectus Zone of Tiwari & Tripathi (1992) from the Lower Talchir Formation that appears below the Plicatipollenites gondwanensis Assemblage Zone bearing diagnostic Permian spores/pollen grains.…”

“…Additionally, a taxonomic revision of illustrated and listed endemic species of the Permian successions in India (e.g. Tiwari & Tripathi, 1992;Aggarwal & Jha, 2013, and their references), is required as previously highlighted in several publications (Truswell, 1980;Stephenson, 2008;Modie & Le Hérissé, 2009;di Pasquo et al, 2015di Pasquo et al, , 2021Barbolini et al, 2018). In the case of those not illustrated taxa a revision of samples of their respective works or the development of new studies to identify Pennsylvanian and Permian guide species is mandatory (see Murthy et al, 2020;di Pasquo et al, 2021).…”
