Hello aspirant

I am sorry but there is no Undergraduate level course in Paleontology in India. You can join any U.G.Course in Geoloogy,Geography, History, Biology which is both botany and zoology,Chemistry or Physics, then you need Masters’ level student in that subject , and zero in on Paeontological aspects of your subject at M.Phil or Ph.D.

Under paleontology  there are many research positions in Headquarters of Geological Survey of India. They may be deputed to any field points where interesting fossils are found or expected to be found, like the fossils of Dinosaur eggs were found in North West Gujarat some years back.

Hope this helps. All the best.
