Loving this little article i found on New Scientist http://www.newscientist.com/article/dn21783-sauropod-farts-warmed-the-planet.html.
What is says is essentially was our planet getting warmed up through the methane in Sauropods and other dinosaurs. What they reckon is that the global population of these dinosaurs released about 520 million tonnes of methane a year which contributed to warming the Earth and this is apparently estimated to be the same as the total current emissions of greenhouse gas.
Wowza. Also during this time there were no polar ice caps, could this be because of some massive farting dinosaurs...
Go check the full article.
Cheers.
