Algal plankton turn to hunting to survive and recover from end-Cretaceous impact darkness – Science Advances
The end-Cretaceous bolide impact triggered the devastation of marine ecosystems. However, the specific kill mechanism(s) are still debated, and how primary production…
INTRODUCTION
The asteroid impact at the Cretaceous-Paleogene (K/Pg) boundary 66 million years (Ma) ago triggered a cascading mass extinction through the entirety of the global food web that occurred in a geological instant (days to years) (13). From giant marine reptiles to sharks and ammonites, down to microscopic plankton, most marine vertebrates and invertebrates were eliminated, leaving an ocean bereft of diversity and biomass (1, 4). The precise kill mechanism(s) associated with the impact…
