Herein, the major objective is to discuss the validity of species determination of the larger benthic foraminifera Alveolina from the Umlatdoh Limestone that were used as zonal index markers for applying the shallow benthic zones (SBZs) by Pereira et al. (2022). This group of larger benthic foraminifera (LBF) is widely used in the application of biostratigraphy to Eocene shallow-water successions. It displays a noteworthy diversification rate over the Eocene and a wide geographical occurrence (Samanta, 1993; Hottinger, 2001; Drobne et al., 2011) that extends throughout the tropical and subtropical shelves of the western to eastern...
