Process of dinosaurs' extinction under probes

Some paleontologists have reportedly suggested that dinosaurs might have already been ''on the road'' to extinction before an asteroid from ahigh crashed into the earth and ''finished the job''. 'In the process of decomposition, the many dead bodies of the mammoth animals must have released a huge quantity of toxic materials and 'polluted the air. Some of the fairly toxic substances - in addition to the flatulence the beasts passed out while they were still alive -might have also caused climate change that, in turn, led to even more deaths of the animals.
