概要	Dental microwear texture analysis (DMTA) is a method that reconstructs diet and dietary behavior from microscopic wear patterns on the surfaces of teeth. Pioneered by Mark Teaford in the 1980s, DMTA analyzes the three-dimensional texture of wear patterns produced as food is chewed. The method reflects short-term (last few months) dietary composition, complementing longer-term dietary information obtained from stable isotope analysis. DMTA has proven powerful for distinguishing diets rich in tough/fibrous foods from those dominated by hard/brittle foods.	Minimum number of individuals (MNI) is a quantitative zooarchaeological method that estimates the minimum number of animals represented in a faunal assemblage based on the frequency of unique skeletal elements. Developed by Theodore White in 1953, it is one of the most widely used techniques for analyzing animal bone assemblages from archaeological sites. The MNI method helps archaeologists understand hunting and butchering patterns, interpret subsistence practices, and assess the diversity of fauna exploited by past human populations.
