Due to time-averaging (age mixing), fossils preserved together within single strata typically represent organisms that died at different times. The extent of time-averaging determines the temporal resolution of fossil samples and represents one of the most fundamental characteristics of the paleobiological data. Quantitative dating of skeletal remains from present-day depositional systems and numerical modeling both predict that typical paleontological samples should be mixed temporally over centennial-to-millennial time scales. However, the resolution of samples varies notably across taxa and environmental settings. Despite all challenges and uncertainties, our growing understanding of time-averaging processes is improving our ability to interpret the fossil record.
