Paleo-Environmental Significance of Ichnofossils from the Babaguru Formation of the Cambay Basin, Gujarat, India
Journal Title: Universal Journal of Environmental Research and Technology - Year 2012, Vol 2, Issue 1
Abstract
Ichnofossils are biogenic structures preserved on or within the substrate by an organism during their various movements such as dwelling, feeding, resting etc. Ichnofossils are widely used for the interpretation of the paleo-environment of the sediments / rocks. The present paper documents four ichnospecies from the ferruginous sandstone of the Babaguru Formation (early Miocene), exposed in the Amravati river section, at Bhilod village, Cambay basin, India. The Babaguru Formation consists of four ichnofossils, namely, Laevicyclus mongraensis, Planolites beverleyensis, Skolithos linearis and Skolithos verticalis. The presence of these ichnofossils indicates that ferruginous sandstone of the Babaguru Formation was deposited in shallow water near-shore / foreshore marine environment with moderate to high energy conditions. Less density of the ichnofossils and dominance of only vertical burrows among present burrows may be probably due to the paucity of the nutrients in the sediments.
