Paleopedology's earliest developments arose from observations in Scotland circa 1795 whereby it was found that some soils in cliffs appeared to be remains of a former exposed land surface. During the nineteenth century there were many other finds of former soils throughout Europe and North America. However, most of this was only found in the search for animal and/or plant fossils and it was not until soil science first developed that buried soils of past geological ages were considered of any value.
