Sahni (PhD, Minnesota) is professor emeritus, Panjab University, and (retd.) INSA senior scientist at the Centre of Advanced Study in Geology, Lucknow University, India. He has combined with ease and success the subdisciplines of paleontology, sedimentology and geochronology. Using this three-fold approach, Sahni has been able to highlight the uniqueness of the Indian geological record in terms of the India/Asia collision, duration of the Deccan Trap activity and the Cretaceous/Eary Tertiary microvertebrate paleontology. He has also discovered the bones of a stocky, carnivorous dinosaur with an unusual head crest, named Rajasaurus narmadensis, belonging to a significant line of predatory dinosaurs known from the southern continents. He is a fellow of all the science academies of India, and an honorary member of the American Society for Vertebrate Paleontology.
