This video quickly presents the notion of stratotype, which in fact corresponds to a standard section or reference section, which is used to define a geological stage or the limits of a stage. It is internationally recognized and defined according to precise criteria. The name of the original stratotype is used to define the name of the stage.
This video has been put online for beginners in geology, in particular in License 1 and 2 at the University, or for high school students in science courses.
