Different species of ammonites lived at different times within the Mesozoic, so identifying a fossil species can help narrow down when a rock was formed.Correlation can involve matching an undated rock with a dated one at another location.While human cultural remains are rarely found in these layers, sites of human habitation can be relatively dated by comparing associated pollen and diatoms.This is a useful tool in corroborating other methods of dating.
