Absolute geochronology can be accomplished through radioactive isotopes, whereas relative geochronology is provided by tools such as palaeomagnetism and stable isotope ratios.
By combining multiple geochronological (and biostratigraphic) indicators the precision of the recovered age can be improved.
Many people think paleontology is the study of fossils. Paleontology is traditionally divided into various subdisciplines: Micropaleontology: Study of generally microscopic fossils, regardless of the group to which they belong.
Human Paleontology (Paleoanthropology): The study of prehistoric human and proto-human fossils.usage: The usual singular of this noun, taken from Latin, is stratum: the lowest stratum in society.The plural is strata: Several strata of settlement were discovered in the evacuation.“There is one quite astonishing example of the unwillingness of ‘Flood geologists’ to consider the implications of their theory.The sedimentary rocks are arranged in clearly defined layers, or strata.
