GEOLOGY

Detailed explanation-1: -A paleontologist collects as many fossils as possible from a rock or sediment. Once the fossils are prepared by scraping and cleaning, they are sorted by geometry. Fossils with very similar geometry are assumed to belong to a single species.

Detailed explanation-2: -In short, paleontology is the study of what fossils tell us about the ecologies of the past, about evolution, and about our place, as humans, in the world.

Detailed explanation-3: -What is Paleontology? Paleontology is the scientific study of life in the geologic past, based on examination of fossilized remains of once living organisms, such as tracks, bones, teeth, plants, and shells. Fossils are unique, nonrenewable resources that paint a ancient portrait of life on Earth.
