550 million year old Dickinsonia discovered at Bhimbetaka near Bhopal

Dickinsonia fossils have been found in the roof of Auditorium Cave at Bhimbetka Rock Shelters, a UNESCO World Heritage Site for Paleolithic and Mesolithic cave art, near Bhopal, capital of the central Indian State of Madhya Pradesh.

The fossils are identical with Dickinsonia tenuis from the Ediacara Member of the Rawnsley Quartzite in South Australia – clearly reminding of the period prior to the movement of the tectonic plate. That’s when this landmass would have been closer to Australia. The fossils show deformation due to lateral impingement, arcuate pieces missing, and alignment. They are within the late Ediacaran, Maihar Sandstone of the Bhander Group, in red sandstones.

This new occurrence was first published in the February edition of Gondwana Research. The research article by Gregory J.Retallack, Neffra A.Matthews, Sharad Master, Ranjit G.Khangar and Merajuddin Khan, confirms assembly of Gondwana land by 550 Million years ago but not reconstructions adjusted for true polar wander.
