Fig. 3 in Developing Best Practice In Micropalaeontology: Examples From The Mid-Cretaceous Of The Zagros Mountains

Fig. 3 Early – mid-Cretaceous Zagros biozonations (mostly assemblage zones or biofacies) utilising larger benthic foraminifera. The Wynd (1965) zonation and Sissingh (1977) zonations are based on data presented in Motiei (1993). Sampò (1969) and Kalantari (1976) are published schemes, whilst that of Ammen & Gharib (2014) is a scheme using more modern taxonomic concepts. LAD = Last Appearance Datum. FAD = First Appearance Datum. s.l. = sensu lato. No numerical scaling of the geological timescale is implied. The age assignments and taxonomic nomenclature are often outdated, and the uncertainty precludes precise calibration of stage boundaries and the precise relationship of one zonal scheme to another.
