The column labeled "Abundance" describes the relative proportion of calcareous nannofossils in each sample compared with other constituents such as other types of microfossils or mineral components such as clay (A = abundant). What, if anything, is micropaleontology? Small animals can also form microfossils, and in some cases, tiny fragments of bone or other hard tissues from larger animals can be found in the microfossil record as well. The technique is highly sensitive, non-destructive, time-efficient and avoids the need for sample pretreatment. I would definitely recommend Study.com to my colleagues.
