In archaeology, a type site (or type-site, or typesite) is a site that is typical of a particular archaeological culture. For example, the type site of the Pre-Pottery Neolithic A culture is Jericho, in the West Bank, while the type site of the pre-celtic/Celtic Bronze Age Hallstatt culture is the lakeside village of Hallstatt, Austria. A type site contains artifacts which are typical of that culture. Type sites are often the first or foundational site discovered about the culture they represent.
In geology the term is used similarly for a site considered to be typical of a particular rock formation etc.
