Tóm tắt	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.	The number of identified specimens, universally abbreviated NISP, is the most basic quantitative measure in zooarchaeology: a simple count of every bone or bone fragment that an analyst can identify to a taxon. It is the first number computed for almost any faunal assemblage because it is fast, transparent, additive across deposits, and reproducible. Yet, as Reitz and Wing emphasize and Lyman dissects in detail, NISP is an observation count rather than an animal count, and it is distorted by fragmentation, by recovery technique, and by the fact that fragments of a single bone are not independent of one another. Understanding precisely what NISP does and does not measure is the foundation on which all other faunal abundance estimates rest.
