mya = million years ago

Craftily taking samples from gas bubbles trapped inside fossiized tree sap, nerbs have discovered that jurassic air was 31% oxygen. This meant trees grew huge and the land was lush. The whole world was a smorgas-bord for constantly grazing herbivores and they became huge too. Bigger veggies called for bigger predators - it would be a shame to let all of that meat go to waste - and mother nature duly obliged.

The end of the jurassic saw cooling-down on a world wide scale. Dinosaurs struggled to adapt. Climate change meant a change in foliage therefore a change of diet, and the super-saurs were replaced with smaller more fuel efficient models.
