This paper compares shallow water PETM record from India with model simulations. Shallow marine PETM succession are rare; here we presented from the low paleolatitude NE India (eastern Tethys). The absence of coral reefs in NE India, in contrast to other Tethyan records, was driven by very high temperatures. Linking biotic records of this section with climate modelling allow to interpret the biotic differences across the Tethyan region.

| Abstract | The Paleocene Eocene Thermal Maximum (PETM) is associated with major extinctions in the deep ocean, and significant paleogeographic and ecological changes in surface ocean and terrestrial environments. However, the impact of the associated environmental change on shelf biota is less well understood. Here we present a new PETM record of a low paleolatitude shallow-marine carbonate platform from Meghalaya, NE India (eastern Tethys). The biotic assemblage was distinctly different to other Tethyan PETM records dominated by larger benthic foraminifera and calcareous algae both in the Paleocene and Eocene. A change in taxa and forms indicating deeper waters with a concurrent decrease in abundance of shallow water algae suggests a sea-level rise during the onset of the PETM. The record is lacking the ecological change from corals to larger foraminiferal assemblages and the Lockhartia dominance, characteristic of other sections in the Tethys. Comparison with a global circulation model (GCM) indicates high regional temperatures in the Thanetian which may have excluded corals from the region. Furthermore, the regional circulation pattern is isolating the site from the wider Paratethys. A change in taxa and forms indicating deeper waters with a concurrent decrease in abundance of shallow water algae suggests a sea-level rise during the onset of the PETM. Our study highlights the need for a diverse global perspective on shallow marine response to the PETM and the strength of coupling data to global climate models for interpretation. |
