GEOLOGY

Detailed explanation-1: -Micropaleontology involves the study of organisms so small that they can be observed only with the aid of a microscope. The size range of microscopic fossils, however, is immense. In most cases, the term micropaleontology connotes that aspect of paleontology devoted to the Ostracoda, …

Detailed explanation-2: -Micropaleontology is also a tool of geoarchaeology used in the archaeological reconstruction of human habitation sites and environments. Changes in the microfossil population abundance in the stratigraphy of current and former water bodies reflect changes in environmental conditions.

Detailed explanation-3: -MICROFOSSILS ARE the tiny remains of bacteria, protists, fungi, animals, and plants. Microfossils are a heterogeneous bunch of fossil remains studied as a single discipline because rock samples must be processed in certain ways to remove them and microscopes must be used to study them.

Detailed explanation-4: -Chalk, for example in the shells of coccoliths and foraminifera, Phosphate, for example in bones of vertebrates, Organic compounds, for example in pollen and spores.

Detailed explanation-5: -UCL Micropalaeontology The production of these organisms is a basic component of the global biogeochemical system, intimately linked to present and past environmental change. In this way microfossils are keys to Palaeoceanography and Palaeoclimatology and to understanding the evolution of the biosphere.
