Fig. 6 in Developing Best Practice In Micropalaeontology: Examples From The Mid-Cretaceous Of The Zagros Mountains

Fig. 6 Further examples of relatively recent Zagros mid-Cretaceous biozonation schemes that utilize larger benthic foraminifera. No numerical scaling of the geological timescale is implied. The age assignments and taxonomic nomenclature are often outdat- ed, and the uncertainty precludes precise calibration of stage boundaries and the precise relationship of one zonal scheme to another.
