Super volcano killed the dinosaurs, say some scientists
The extinction of the dinosaurs – thought to be caused by an asteroid impact some 65 million years ago – was more likely to have been caused by a 'mantle plume' – a huge volcanic eruption from deep within the earth's mantle, the region between the crust and the core of the earth.
This theory, already supported by a significant body of geologists and palaeontologists, is strengthened by new evidence presented at an international conference at Cardiff University.
