Abstract
The present paper deals with the new record of fungal remains from the Subathu Formation exposed along Dogadda-Kotdwar road section in Dogadda, Uttarakhand. The assemblage is composed of 13 species assignable to 10 genera. The important genera are Callimothallus senii, Haplopeltis mucoris, Haplopeltis sp., Parmathyrites sp., Phragmothyrites eocaenicus, Plochmopeltinites sp., Spinosporonites saxenae, Spinosporonites angularis and Trichothyrites padappakkarensis. The presence of microthyriaceous fungi in dominance suggests that the region experienced a warm and humid climate during the course of sediment deposition with thick vegetation providing suitable substrates for the growth and proliferation of fungi. Their presence depicts the prevalence of moist tropical type of vegetation during deposition in the area. The present fungal assemblage is assigned Late Palaeocene-Middle Eocene age.
Highlights
Nowadays, fungal remains studies along with spores/pollen provide significant records for palaeoenvironmental interpretations
The fungal remains recovered from the Subathu Formation exposed along
Based on the occurence of the Callimothalus senii (Late Paleocene - Miocene), Haplopeltis mucoris (Early Eocene), Phragmothyrites eocenicus (Late Paleocene - Middle Miocene), Spinosporonites saxenae (Late Paleocene - Middle Miocene), Spinosporonites angularis (Late Paleocene - Middle Miocene) in the present fungal assemblage, Late Palaeocene-Middle Eocene age is assigned to this horizon of Dogadda-Kotdwar section, Dogadda area, Pauri-Garhwal district, Uttarakhand
Summary
Fungal remains studies along with spores/pollen provide significant records for palaeoenvironmental interpretations. The term “Subathu” was initially coined by Medlicott in 1864 It represents the oldest sequence of the Palaeogene succession of Himalayan Foreland Basin succession. [10] recorded lamellibranch genera Perna, Cardiocardita, Astarte from the Dogadda Formation in Garhwal Synform at Golikhet, Garhwal, U.P. On the basis of fossil records, the Subathu formation is considered to range in age from Upper Palaeocene to middle Eocene and the deposition of the lithounit in marine conditions. On the basis of fossil records, the Subathu formation is considered to range in age from Upper Palaeocene to middle Eocene and the deposition of the lithounit in marine conditions These workers deal with the foraminiferas and vertebrates, the fungal spores and their fruiting bodies seem to have been received no attention. The present study is focused on the fungal remains from the Subathu sediments of the Dogadda area located in the Uttarakhand (Figure 1) because of its relevance in palaeoenvironmental considerations
