What are “Tertiary rocks?
Arduino devised a stratigraphic system in which sedimentary rocks containing fossils were called “tertiary” rocks to distinguish them from igneous and metamorphic rocks present in the cores of mountain ranges (“primary” rocks), the shales and limestones of Europe (“secondary” rocks), and surficial gravel (“quaternary” rocks).
