- •
Plummerita hantkeninoides zone CF1 present in Bidart (France), Gamsbach (Austria)
- •
Low MS Deccan benchmark coincides with a carbonate dissolution event at both sites.
- •
Dissolution event immediately precedes the KTB mass extinction.
- •
Ocean acidification may have resulted in carbonate crisis for planktic foraminifera.
- •
Deccan volcanic main phase-2 may be the likely cause.
