I've googled quite a bit. Other than finding articles that require payment to view I have found nothing usable.
I need a source - possibly a table would be best - of estimated oxygen levels since the Cambrian. Thanks.
- Reason: the only text I have was out of print during the Eocene
when nobody knew reliably about things like atmospheric oxygen levels. Well maybe not quite that old, but it may as well be.
