The approach adopted herein is suggested as an important supplement to other techniques used to infer paleodepth and, moreover, an approach that shows considerable promise for elucidating changes in ramp geometry and calibrating eustatic sea-level changes.

In addition to being excellent paleobathymetric markers, the abundance of some depth-related species, as well as the upper depth-limits of others, allow us to infer possible changes in paleodepth.
A comparison between paleodepth interpretations proposed by Pardo et al.
Paleodepths indicated by the benthic foraminiferal faunas are clearly of great importance to interpret the environment of deposition of the K/Pg sediments.
They also concluded that paleodepths fluctuated between upper bathyal and outer neritic.
Smaller benthic foraminiferal assemblages are widely applied for determination of the paleodepths (e.g.
It characterizes middle neritic (50-80 m) paleodepths. In this study 1m to 3m outcrop sample interval of Panoba Formation have Bolivina gracilis Cushman, Bolivina acerosa Cushman and varieties of Textularids that marks the shallower end of the Bulimina biofacies indicating middle neritic environment, while 3m to 9m outcrop samples of Panoba Formation show increase in biodiversity and abundance of Cibicides and polymorphinids that marks the deeper end of the Bulimina biofacies.
