Stratotype (type section) The designated exposure of a named layered stratigraphic unit or of a stratigraphic boundary that serves as the standard of reference.A stratotype is the specific stratal sequence used for the definition and/or characterization of the stratigraphic unit or boundary being defined. 2. Unit-stratotype.France used the successions of faunas in stratified rocks for mapping. This led to the development of the principle called the law of faunal succession: distinct faunas succeed one another regularly in the rocks. Why fossil faunas work this way was not well understood, however, until the middle 1800s, as a result of the work of Darwin and Wallace.revised by Werner E. Piller3 and Marie-Pierre Aubry4.
