In geology, range offset is the time difference between the last fossil occurrence of a taxon and the actual disappearance of this taxon. Range offset can be used as a measure of biostratigraphic precision [1] and determines among others how much information about extinctions can be derived from fossil occurrences.
The range offset of a taxon is defined as [2]
Range offset is strongly affected by sequence stratigraphy. Simulations show that range offset changes by up to three orders of magnitude dependent on the position in the systems tracts. [2]
