The principles of lithostratigraphy were first established by the Danish naturalist, Nicolas Steno, in his 1669 Dissertationis prodromus. [1] A lithostratigraphic unit conforms to the law of superposition, which in its modern form states that in any succession of strata, not disturbed or overturned since deposition, younger rocks lies above older rocks.

Archaeological stratigraphy at the Iron Age site of Goosehill Camp on Bow Hill, West Sussex in Southern England. Neat stratification in Athens (Ceramicus Cemetery). Stratigraphy is a key concept to modern archaeological theory and practice. Modern excavation techniques are based on stratigraphic principles.
Animation showing interpretive grouping and phasing on matrix diagram. The Harris matrix is a tool used to depict the temporal succession of archaeological contexts and thus the sequence of depositions and surfaces on a 'dry land' archaeological site, otherwise called a 'stratigraphic sequence'.
The art of the Upper Paleolithic represents the oldest form of prehistoric art. Figurative art is present in Europe and Southeast Asia , beginning around 50,000 years ago. [ 1 ] [ 2 ] [ 3 ] Non-figurative cave paintings , consisting of hand stencils and simple geometric shapes, are somewhat older, at least 40,000 years old, and possibly as old ...
Portable art (sometimes called mobiliary art) refers to the small examples of Prehistoric art that could be carried from place to place, which is especially characteristic of the Art of the Upper Palaeolithic and Mesolithic eras. Often made of ivory, bone, antlers or stone, these pieces have been found in South Africa all the way up to Eurasia.
Stratigraphy is a branch of geology concerned with the study of rock layers and layering (stratification). It is primarily used in the study of sedimentary and layered volcanic rocks . Stratigraphy has three related subfields: lithostratigraphy (lithologic stratigraphy), biostratigraphy (biologic stratigraphy), and chronostratigraphy ...
A well-known example of a key bed is the global layer of iridium-rich impact ejecta that marks the Cretaceous–Paleogene boundary (K–T boundary). Palynology , the study of fossil pollens and spores, routinely works out the stratigraphy of rocks by comparing pollen and spore assemblages with those of well-known layers—a tool frequently used ...
In archaeology a section is a view in part of the archaeological sequence showing it in the vertical plane, as a cross section, and thereby illustrating its profile and stratigraphy. This may make it easier to view and interpret as it developed over time. Stylised section drawing
