Question

Study of fossils is
(a)Palaeontology
(b)Herpetology
(c)Saurology
(d)Organic evolution

Answer 1

They are the study of ancient life. It’s one among the historical sciences that aims to explain the phenomenon of the past and reconstruct the causes. They lie between biology and geology.

Complete answer:
Paleontology is the scientific research of life of the geologic past that requires the analysis of plant and animal fossils, together with such microscopic size and preserved in rocks. It is covered with all facts of the biology of ancient life forms which includes their shape and structure, evolutionary patterns, taxonomic relationships with one another and with modern living species, geographic spread, and correlations with the environment. Paleontologists use fossil remains to know different aspects of extinct and living organisms. Single fossils may carry the facts about an organism’s life and environment.

Additional Information: The field of paleontology has many sub disciplines. Within the case of paleontology, sub disciplines can specialise in a selected fossil type or a selected aspect of the world, like its climate.
One important sub discipline is vertebrate paleontology, the study of fossils of animals with backbones. Invertebrate paleontologists examine the fossils of animals without backbones. Paleobotanists study the fossils of ancient plants. Micropaleontology examines the fossils of microscopic organisms.
So, the right answer is ‘Palaeontology’.

Note: Paleontologists generally use approaches supported by cladistics, a way for understanding the evolutionary "family tree" of a group of organisms. These are a few medicinal and preventive uses for a few fossils. Largely the utilization of fossils as medicine may be a matter of consequence. However, the consumption of certain fossils has been proven to assist against stomach acidity and mineral depletion.
