Poison gas 'caused' great dying
The Earth's greatest mass extinction was probably caused by poisonous volcanic gas, according to a study published in the journal Geology.

This "great dying" 250 million years ago killed off more than two-thirds of reptile and amphibian families.

But it also facilitated the rise of the dinosaurs, which would rule Earth for the next 185 million years.

New evidence comes from molecules preserved in rocks laid down at the time of the extinction.
