Type locality (geology)

In some natural sciences, type locality (Latin locus typicus) is the typical or representative location and is typically the first example of a newly discovered or described object. Often it is namesake for the term.

It is most commonly used in geology for formations, structures, rock types, minerals and fossils. A synonymous term is type locale. It is also used in biology. The term is similar to the term type site in archaeology or the term type specimen in biology.
