Paleontology or palaeontology is the scientific study of life that existed prior to, and sometimes including, the start of the Holocene Epoch (roughly 11,700 years before present). It includes the study of fossils to determine organisms' evolution and interactions with each other and their environments (their paleoecology).
Paleontologists who engage in fieldwork may have to endure extreme weather conditions. They may be required to travel frequently to remote locations and carry lots of research equipment in backpacks, which is likely to make the task physically strenuous. Paleontologists who are employed as faculty members at universities or research institutes have regular 40-hour weeks in a comfortable environment.
Pramatha Nath Bose was a pioneering Indian geologist and paleontologist. P. N. Bose was educated at Krishnagar College and later at St. Xavier's College of theUniversity of Calcutta when he obtained a Gilchrist scholarship to study in London in 1874. During his study at Cambridge he became a friend of Rabindranath Tagore. He was one of the early Indians to join the Geological Survey of India as a graded officer. His initial work was on the Siwalik fossils. He is credited with the discovery of petroleum in Assam and the setting up of the first soap factory in India and was instrumental in the setting up of Jamshedpur by writing to J. N. Tata about the rich iron ore reserves
Dhirendra Kishore Chakravarti was an Indian geologist and palaentologist, who worked at Banaras Hindu University in the Geological Museum (now part of the Institute of Science).In 1934, he was the first Indian to describe a species of dinosaur, Brachypodosaurus gravis (now considered dubious). In 1935, he contested the interpretation of Lametasaurus indicus as an armoured dinosaur, arguing that it was a chimera. In 1982, the Geological Society of India organised a Festschrift in his honour.
