概要	Soil micromorphology is the microscopic study of undisturbed soils and sediments in thin section to reconstruct how archaeological deposits formed and were altered. An oriented block is cut from a deposit without disturbing its internal structure, hardened with resin, and ground into a slice about thirty micrometers thick that can be examined under a petrographic microscope. At that scale the analyst can read features invisible in the field — the arrangement of mineral grains, microscopic charcoal and bone, plastered surfaces, dung, trampling fabrics, and the pedofeatures left by water, roots, and burrowing organisms. Developed for soil science by Walter Kubiëna and adapted for archaeology by geoarchaeologists such as Goldberg, Macphail, and Courty, micromorphology is the highest-resolution tool for interpreting site formation, occupation surfaces, and anthropogenic deposits in their original spatial context.	Taphonomic analysis is the study of everything that happens to animal remains between the death of an organism and the moment an archaeologist records its bones, and of how those processes shaped the assemblage we recover. Coined by the paleontologist Ivan Efremov as the 'laws of burial,' taphonomy became a rigorous archaeological method through R. Lee Lyman's Vertebrate Taphonomy, which systematized the reading of bone surfaces, weathering, breakage, and skeletal-part survival. The goal is twofold: to identify which agents — humans, carnivores, water, weathering — accumulated and modified the bones, and to measure how much of the original assemblage was destroyed by density-mediated attrition. Because every quantitative faunal measure depends on these formation processes, taphonomic analysis is the indispensable prelude to interpreting subsistence and behavior from animal bone.
