Q. Tharosaurus indicus, dinosaur fossils from the Middle Jurassic period, was recently discovered in which region?
Answer:
Thar Desert, India
Notes: Recently, scientists from IIT Roorkee made a discovery by characterizing dinosaur fossils from the Middle Jurassic period, unearthed in the Thar Desert near the Jaisalmer Basin, by the Geological Survey of India. The fossils belong to a species known as Tharosaurus indicus, a member of the Dicraeosauridae family within the superfamily Diplodocoidea. These fossils represent the first dicraeosaurid sauropods ever found in India and are approximately 167 million years old, making them the world's oldest known diplodocoid fossils.
The scientists coined the name Tharosaurus indicus, drawing from "Tharo" (referring to the Thar desert), "sauros" (Greek for lizard), and "indicus" (indicating its Indian origin). These dinos were distinct within their family, characterized by smaller size and shorter necks and tails compared to their long-necked sauropod counterparts. Sauropods originated during the Jurassic period around 200 million years ago and were a dominant group of dinosaurs, surviving until the late Cretaceous period, when dinosaurs met their demise. While dicraeosaurid fossils have been found in other parts of the world, this discovery sheds new light on prehistoric India's biodiversity.
