Fusulinid from the Plattsmouth Chert, Red Oak, Iowa ().Micropaleontology can be roughly divided into four areas of study on the basis of microfossil composition: (a) calcareous, as in coccoliths and foraminifera, (b) phosphatic, as in the study of some vertebrates, (c) siliceous, as in diatoms and radiolaria, or (d) organic, as in the pollen and spores studied in palynology.
Palynology is the study of microorganisms and microscopic fragments of mega-organisms that are composed of acid-resistant organic material and occur in sediments, sedimentary rocks, and even some metasedimentary rocks.
A microfossil is a fossil that is generally between 0.001 mm and 1 mm in size, [2] the visual study of which requires the use of light or electron microscopy.A fossil which can be studied with the naked eye or low-powered magnification, such as a hand lens, is referred to as a macrofossil.
See also microfossils and palynology. Paleovirology examines the evolutionary history of viruses on paleobiological timescales. Paleobiochemistry uses the methods and principles of organic chemistry to detect and analyze molecular-level evidence of ancient life, both microscopic and macroscopic.
Fossil preparation is a complex of tasks that can include excavating, revealing, conserving, and replicating the ancient remains and traces of organisms. It is an integral part of the science of paleontology, of museum exhibition, and the preservation of fossils held in the public trust.
Molecular paleontology refers to the recovery and analysis of DNA, proteins, carbohydrates, or lipids, and their diagenetic products from ancient human, animal, and plant remains. [ 1 ] [ 2 ] The field of molecular paleontology has yielded important insights into evolutionary events, species' diasporas , the discovery and characterization of ...
Clinical pathology is a medical specialty that is concerned with the diagnosis of disease based on the laboratory analysis of bodily fluids, such as blood, urine, and tissue homogenates or extracts using the tools of chemistry, microbiology, hematology, molecular pathology, and Immunohaematology.
Micropaleontologists study microscopic fossils, including organic-walled microfossils whose study is called palynology. There are many developing specialties such as paleobiology , paleoecology , ichnology (the study of tracks and burrows) and taphonomy (the study of what happens to organisms after they expire).
