Spore-pollen assemblages of the Bowen Basin, Queensland (Australia): Their relationship to the Permian/Triassic boundary

Vegetation history across the Permian–Triassic boundary in Pakistan (Amb section, Salt Range)

“…However, in the Australian Bowen Basin sequences, spore abundances of~80% (Lundbladispora brevicula) are known from the lower part of Rewan Formation (de Jersey, 1979). Foster (1982) also reported cavate trilete spore abundances of 44-80% in the Protohaploxypinus microcorpus Zone of the lower Rewan Formation, which can be correlated with the palynological assemblages of the Chhidru Formation in Pakistan . The Lower Triassic Kockatea Shale in Western Australia is also known for its high lycopod spore abundances (Balme, 1963).…”

Temnospondyl diversity of the Permian-Triassic Colonia Orozco Local Fauna (Buena Vista Formation) of Uruguay

“…The Permo-Triassic succession in Australia is represented by the Rewan Group, which includes the Upper Permianlowermost Triassic Sagittarius Sandstone conformably overlied by the Lower Triassic Arcadia Formation (Warren et al, 2006). The age of the Sagittarius Sandstone is supported by palinological and radiometric data (Foster, 1982;Archbald & Dickens, 1996in Warren et al, 2006 thus suggesting an earlier Triassic age than that previously proposed for the Arcadia Formation, closer to the P-T boundary (Warren et al, 2006). Nevertheless and according to Warren et al, (2006), the P-T boundary in Australia remains controversial.…”

The Permian–Triassic palynological transition in the Guryul Ravine section, Kashmir, India: implications for Tethyan–Gondwanan correlations

“…Some differences are apparent at species level between these assemblages but these may represent either intra-gondwanan provincialism or alternative approaches to taxonomic appraisal between palynologists from different regions. Significantly, Lunatisporites and lycophytic spores increase in abundance in the latest Permian of Australia and this pattern persists into the Early Triassic (Balme, 1963;Foster, 1982;Helby et al, 1987;Backhouse 1991;Shi et al, 2010). The presence of both of these spore-pollen groups in units C-E 1 of the Zewan and basal Khunamuh formations supports a stratigraphic position close to the PTB.…”

“…Basic similarities between the palynofloras of unit E 1 of the Khunamuh Formation and the latest Permian Protohaploxypinus microcorpus and earliest Triassic Lunatisporites pellucidus palynozones of Australia (Foster, 1982) are evidenced by the shared presence of Crescentipollenites/ Striatopodocarpites and Protohaploxypinus species, Playfordiaspora cancellosa, several lycophyte spore taxa and Reduviasporonites chalastus. Some differences are apparent at species level between these assemblages but these may represent either intra-gondwanan provincialism or alternative approaches to taxonomic appraisal between palynologists from different regions.…”

“…Amongst the core regions of Gondwana beyond India, the palynostratigraphy of Permian-Triassic transitional successions has been studied extensively from Australia (Foster, 1979(Foster, , 1982(Foster, , 1983Helby et al, 1987;Backhouse, 1991), Antarctica (Kyle, 1977;Kyle and Schopf, 1982;Farabee et al, 1990Farabee et al, , 1991Lindström, 1995;McLoughlin et al, 1997;Collinson et al, 2006;Lindström and McLoughlin, 2007), Madagascar (Wright and Askin, 1987), South Africa (Steiner et al, 2003), and East Africa (Hankel, 1992).…”
