What type of rock might contain evidence of past life.
Site type provides important information for archaeologists. It indicates the likely function of the site and allows archaeologists to predict the types of artifacts and ecofacts likely to be uncovered. An open site, for example, will rarely contain well-preserved perishable artifacts or features because of damage from wind, rain, heat, and cold.
