Abstract
On the basis of a Mo-based geochemical proxy calibrated to the fossil record of fish, Dahl et al. argued that oxygen levels in the early Paleozoic were 15–50% of present atmospheric levels (PAL) and probably no more than a few percent PAL for the previous 2 billion years ( 1). It is an interesting result, but the study raised a number of issues.
