Ar40; half-life of 1. 26kkk years; acts as measure of time: therefore, fossils not dated directly; date volcanic rocks or ash falls they are associated with, preservation conditions = Influences likelihood of recovery = good: dry, hot climates or very cold environments (anaerobic environments because inhibits growth of organics); bad: hot/moist environments, areas with major seasonal changes (wet and dry cycle) Material of object = organic materials do not preserve as well as non-organic. Hammerstone = tool used to strike the stone.
