Were sauropod dinosaurs responsible for the warm Mesozoic climate?

open access: yesJournal of Palaeogeography, 2012
It was recently postulated that methane production by the giant Mesozoic sauropod dinosaurs was larger than the present-day release of this greenhouse gas by nature and man-induced activities jointly, thus contributing to the warm Mesozoic climate.
