Macro‐charcoal, as direct evidence of palaeo‐wildfires, is a common constituent throughout an Early Permian (Cisuralian) inertinite‐rich coal seam from the Dhanpuri Coal Mine (Barakar Formation, Sohagpur Coalfield, Madhya Pradesh, India). The continuous presence macro‐charcoal within this particular demonstrates that fires occurred repeatedly in source vegetation seam. Based on these remains, anatomical assessment diversity and taxonomic composition vegetation, which experienced wildfires...
The first record of palaeo-wildfire evidence in the form charcoal is documented from Late Permian Zewan Formation Kashmir region, northwest Himalaya. This fragments tracheids that show homogenized cell walls, a characteristic feature charcoal. Considering palaeowildfire studies provide important palaeoecological information, present study significant, as it allows reconstructing new information about environmental conditions during deposition sediments Formation.
Exceptionally well-preserved organic remains of thecamoebians (testate amoebae) were preserved in marine sediments that straddle the greatest extinction event Phanerozoic: Permian-Triassic Boundary. Outcrops from Late Permian Zewan Formation and Early Triassic Khunamuh are represented by a complete sedimentary sequence at Guryul Ravine Section Kashmir, India, which is an archetypal boundary [1]. Previous biostratigraphic analysis provides chronological control for section, perspective faunal...

Well preserved plant fossil assemblage recorded for the first time from Barakar Formation of Sharda Open Cast Mine, Sohagpur Coalfield, Shahdol District, Madhya Pradesh is documented in this study. The comprises orders Equisetales, Glossopteridales and Cordaitales. Equisetales represented by unidentifiable leafless equisetalean axes bearing nodes internodes, one species Gangamopteris (Gangamopteris intermedia) seven Glossopteris (Glossopteris communis, G. gigas, giridihensis, indica,...
Platyspermic and radiospermic gymnospermous seeds are documented from the top seam of Barakar Formation, Makardhokra Open Cast Project, Umrer Coalfield, Nagpur District, Wardha Basin, Maharashtra. A variety seed types including Cordaicarpus sp., zeilleri, Samaropsis feistmantelii, Rotundocarpus ovatus a new species, viz. mucronatus systematically described. The largely comparable with those described Karharbari Formation Damodar Basin. Besides adding to knowledge flora this communication...
Abstract A large number of Dicroidium -frond, considered as the marker Early Triassic Gondwana flora, are discovered for first time with well preserved cuticle from Permian (Lower Gondwana) sequence Barakar Formation, Satpura Basin, India. The presence in Late mixed floral zone Jordan has been viewed its possible origin paleotropics but evidence hand exhibits Gondwanic derivation and threatens recognition flora Middle association Lower Glossopteris Upper Ptilophyllun flora.
Morphological and taxonomic features of dispersed sterile scale leaves collected from the Barakar Formation Pench, Kanhan Pathakhera coalfields Satpura Gondwana Basin, Madhya Pradesh are described. The normally described as morphological types without their assignment to status. Due this practice, identity significance have gone astray in Glossopteris flora. presence large number with different present assemblage has helped discuss structure, nature affinity. been assigned genera species...
The morphological and cuticular features of well-preserved leaves Glossopteris stenoneura Feistmantel collected from Barakar Formation Churulia area, Raniganj Coalfield are analyzed. study indicates that spathulate shaped distinct in having narrow-elongate trapezoidal meshes near the midrib short, narrow margin leaves. Cuticle is amphistomatic, surface upper cuticle characteristically shows fine striations over vein area. Stomata anomocytic, ovalelongate with cutinized guard cells....
