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. Paleontology incorporates knowledge from biology, geology, ecology, archaeology, and even computer science to understand the processes that have led to the origination and eventual destruction of the different types of organisms since life arose. In petroleum exploration, the biggest aim through micropaleontology is to determine the accurate age in the drilling well or to determine the correct stratigraphic position with the help of microfossils.
