All of the taphonomic and other factors involved in fossilization, exposure and collection of fossils affect the preservation state, the condition in which the fossils become available for collection. These factors also determine what should be done to, at the very least, at least maintain that preservation state, and ideally provide a stabilized specimen that can, if desired, be restored. Weathering of rocks and their contained fossils is always a combination of mechanical and chemical processes. The collection of fossils in the field, and later work in the laboratory, attempts to halt or slow those processes (Rixon, 1976; Converse, 1984).
