In geoscience, paleosol (palaeosol in Great Britain and Australia) is an ancient soil that formed in the past. The definition of the term in geology and paleontology is slightly different from its use in soil science .
Alfisol paleosol cut by stream channel sandstone in Middle Devonian Oneonta Formation near East Windham, New York. The Mata Amarilla Formation, a formation in the Austral Basin in southern Patagonia, Argentina is the location known for the preservation of podocarp-dominated fossil forests. In the eastern area of the middle section of the Mata ...
Vertisol paleosol Watervol Onder Mollisol in Dayville, Oregon. Chemical analysis of soil fossils generally focuses on their lime content, which determines both their pH and how reactive they will be to dilute acids. Chemical analysis is also useful, usually through solvent extraction to determine key minerals. This analysis can be of some use ...
Astropedology is the study of very ancient paleosols and meteorites relevant to the origin of life and different planetary soil systems. It is a branch of soil science concerned with soils of the distant geologic past and of other planetary bodies to understand our place in the universe. [1]

Usselo is the type site for the 'Usselo Soil', which is also known as either the 'Usselo horizon' or 'Usselo layer'. It is a distinctive and widespread Weichselian (Lateglacial) buried soil, paleosol, that is found within Lateglacial eolian sediments known as 'cover sands' in the Netherlands, western Germany, and western Denmark.
Gregory John Retallack (born 8 November 1951) is an Australian paleontologist, geologist, and author who specializes in the study of fossil soils (paleopedology).His research has examined the fossil record of soils though major events in Earth history, extending back some 4.6 billion years. [1]
Map of the United States showing what percentage of the soil in a given area is classified as an Ultisol-type soil. The great majority of the land area classified in the highest category (75%-or-greater Ultisol) lies in the South and overlays with the Piedmont Plateau, which runs as a diagonal line through the South from southeast (in Alabama) to northwest (up into parts of Maryland).
