Stinking seas not to blame for 'mother of all mass extinctions'

Scientists on Sunday said they had ruled out a key hypothesis to explain
Earth's greatest extinction, when 95 percent of marine species and 70
percent of land species were wiped out.

British researchers, reporting on Sunday in the journal Nature
Geoscience,
ruled out a leading theory that the oceans became starved of oxygen and rich
with sulphide, causing marine life to die out.

A team led by David Beerling of the University of Sheffield in northern
England created a two-dimensional computer model of atmospheric chemistry to
test this notion.

Ah, a two dimensional model - wonder which two dimensions.
