Dinosaurs ‘gassed’ themselves into extinction, British scientists say

I didn’t delve into the primary literature (if there was any, I didn’t see any citation in the above article) but right on the surface I would have to question the statements. There would have to be a whole lot fewer giant dinosaurs than the number of grass eaters we have today and while the dinosaurs would eat a lot more than our current grazers, I suspect the amount of vegetation consumed per ‘herd’ would work out to be about the same.
It was funny thinking about those huge farting noises, though!
