Fate of calcareous nannofossils during the Rhaetian (Late Triassic) : evidence from the Northern Calcareous Alps, Austria
Calcareous nannofossils evolved in the global ocean from the Carnian (early Late Triassic) and have contributed to the accumulation of biogenic calcium carbonate in marine sediments since then. Bio-diversification and bio-productivity became more significant in the Rhaetian (Late Triassic), representing an important period to understand the dynamics of calcareous nannofossil evolution. The calcare
