Figure 1 Estimated emissions. Estimated sauropod methane production compared to total modern (both natural and anthropogenic), global pre-industrial and estimated modern methane production from ruminants. Even reducing our estimate by half still predicts a major role for sauropod methane in the Mesozoic.
