Mega eruption may have wiped out [Cambrian] life


Mega eruption may have wiped out life

Scattered rafts of black lava over northern and central Australia are really part of one gigantic volcanic field that appears to be one of oldest and largest on Earth, geologists believe.

If so, the half billion year old eruption might be the culprit in the first mass animal extinction event in the history of life.

Australian geologists used the chemical signatures of the far-flung basalt lava rocks and their ages to connect them to a single huge volcanic eruptive episode between 505 and 508 million years ago...
