Cambrian Explosion: role of oxygen (Introduction)

by David Turell , Wednesday, February 19, 2014, 18:47 (3930 days ago) @ David Turell

Nature has an article on oxygen levels. Paywalled. It seems they can measure anceint levels:-http://www.nature.com/nature/journal/v506/n7488/full/nature13068.html?WT.ec_id=NATURE-20140220
