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.
Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. [1] This includes the study of body fossils, tracks (), burrows, cast-off parts, fossilised feces (), palynomorphs and chemical residues.
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.
The microfossils within the limestone, about the size of a thumbnail, were found to be ancient foraminiferans only found in what is now Europe. - Courtesy Marcus Key, Dickinson College Geosciences ...
