Lucknow, Aug 8 – Scientists from the Indian Institute of Know-how (IIT)-Roorkee and Geological Survey of India (GSI) have found the oldest fossil stays of a long-necked, plant consuming dicraeosaurid dinosaur in Jaisalmer, Rajasthan.
The research revealed in ‘Scientific Reviews’, a global journal by the publishers of Nature, not solely reveals that is still are 167 million years outdated but in addition that they belong to a brand new species unknown to scientists to this point.
Former director of Birbal Sahni Institute Palaeosciences (BSIP), Lucknow, Sunil Bajpai, who’s presently the Chair Professor of Vertebrate Paleontology within the Division of Earth Sciences, IIT-Roorkee and his IITian colleague Debajit Datta, a nationwide post-doctoral fellow, carried out the detailed research of the fossils.
“A scientific fossil exploration and excavation program initiated by GSI in 2018 within the Center Jurassic (~ 167 Ma) rocks within the Jaisalmer area of Rajasthan, has led to this discovery. The fossils had been collected by the GSI officers Krishna Kumar, Pragya Pandey and Triparna Ghosh beneath the supervision of Debasis Bhattacharya after which we studied it for round 5 years,” stated former BSIP director Sunil Bajpai.

In keeping with scientists, fossils of dicraeosaurid dinosaurs have been discovered beforehand in North and South America, Africa and Asia (China) however such fossils weren’t recognized from India. The invention additionally suggests India was a serious centre of dinosaur evolution, they stated.
The fossil stays had been collected from the Jaisalmer area in 2018 and thereafter a bunch of six scientists from two premier organizations carried out analysis on it for round 5 years.
Their research revealed that the first-ever dicraeosaurid dinosaurs present in India existed within the Jaisalmer area.
The brand new dinosaur has been named ‘Tharosaurus indicus’, the primary title referring to the ‘Thar desert’ the place the fossils had been discovered, and the second title is after its nation of origin, i.e., India.
He stated the primary significance of this discovery lies in its age. The rocks by which it was discovered are dated to be round 167 million years outdated which makes this new Indian sauropod not solely the oldest recognized dicraeosaurid but in addition globally the oldest diplodocoid (broader group which incorporates dicraeosaurids and different intently associated sauropods).
Prof Bajpai stated the brand new Indian dinosaur is a part of an extended lineage that originated in India and underwent speedy dispersal throughout the remainder of the world.
Explaining additional, Debajit Datta from IIT-Roorkee stated, “The research comes up as a substitute for earlier theories on sauropods which urged that the oldest dicraeosaurid was from China (about 166–164 million years outdated) and that the ancestors of diplodocids and neosauropods had been solely current in Asia or the Americas.”
He stated the Indian Tharosaurus is older than its Chinese language kinfolk. Coupled with different primitive dinosaurs in India similar to Barapasaurus and Kotasaurus from the early Jurassic rocks of central India, the brand new Indian discovery strongly means that India was a serious centre for the origin and radiation of neosauropod dinosaurs.
