Greenhouse gas dinosaurs

Need to heat your planet? Install some dinosaurs. The biggest plant-eating dinosaurs pumped out huge amounts of greenhouse gas, helping to keep Earth toasty warm, according to new calculations.

New duck-billed dinosaur was a 'chewing machine'

Prehistoric plants had a lot to fear from Gryposaurus monumentensis – with around 800 teeth inside its massive jaws, the 9-metre-long (30 feet) duck-billed dinosaur could have made a snack of tree branches as well as foliage. The creature lived in what is now southern Utah, some 75 million years ago.
