New Delhi: Researchers have found fossils of one of many Earth’s earliest recognized multicellular animals — the 550-million-year-old Dickinsonia — on the roof of the Bhimbetka rock shelters in Madhya Pradesh.

Dickinsonia is an extinct genus of basal animal that lived throughout the late Ediacaran interval in a geographical space now divided into Australia, China, India, Russia and Ukraine.

The particular person Dickinsonia sometimes resembles a bilaterally symmetrical ribbed oval. Its fossils are recognized solely within the type of imprints and casts in sandstone beds.

The specimens present in Bhimbetka are round 17 inches lengthy, whereas those which were present in different components of the world exceeded 4 ft in size, the researchers from Geological Society of India (GSI), Nagpur, Maharashtra, famous.

The discovering, printed within the journal Gondwana Research, confirms shut proximity of Australia and India, in accordance with the researchers.

“Dickinsonia fossil was first found in 1947 in Flinders Ranges of South Australia. Its fossils have additionally been found in Ukraine, Russia and China, Ranjit Khangar Director & Coordinator, GSI, instructed PTI.

“Bhimbetka Rock Shelters, a UNESCO World Heritage Site for Paleolithic and Mesolithic cave art, near Bhopal, is once again highlighted worldwide due to the first discovery of oldest animal fossil, Dickinsonia from India,” Khangar mentioned.

The new fossils have been found on the final day of 36th International Geological Congress 2020 subject journey carried out by GSI in March final yr. However, it took the workforce virtually a yr to publish the findings.

Other teammates concerned within the research have been from the University of Oregon within the US, National Operations Center, Bureau of Land Management, Geospatial Section, US, and the University of Witwatersrand in South Africa.

“Dickinsonia is the earliest Ediacaran multicellular animal life yet found — predating explosion of life in Cambrian Period (around 541 million years) in geological time scale,” Merajuddin Khan, senior geologist and member of GSI, Nagpur, famous.

“Palaeobiologists believe that these earliest living creatures used to live in shallow warm seas, as early as 570 million years ago, and are representative of earliest complex life form in animal kingdom,” Khan instructed PTI.

As the fossil is out of attain, a number of digital photos of the positioning have been processed utilizing three-dimensional (3D) modelling, the researchers mentioned.

The geological situation and occurrences of Dickinsonia have been in contrast with fossils reported from South Australia earlier than arriving on the remaining conclusion, they mentioned.
