Mass Extinction

Scientists have discovered the cause of a mass extinction of sea-floor marine organisms 800,000 years ago - which also provides insight into how climate change can impact [blank] deep ocean biota. In a new study [blank] in the journal Nature Communications, scientists from the universities of Nottingham and Durham and the British Geological Survey (BGS), have discovered the cause of a mass extinction within marine organisms called foraminifera. Foraminifera are an important group in relation to biomass in the deep ocean and the cause of their extinction was [blank] unknown. Scientists tested various possible [blank] for the mass extinction and were able to discount others such as ocean cooling. [blank] , they discovered that the extinction was caused by a global change in plankton at the surface of the ocean.
