Campanian question



Hello,

Could it be that  the explanation of the "diversity explosion" among the
dinosaurs in the Campanian was a result of an attempt to adapt to a rapidly
changing environment? The climate was stable until the first half of the
Creteceous period, after that the climate was cooling down, slowly at first
but later on must faster. Also the flora changed at the end of the
Cretaceous period, the first flowering plants eppear. In a stable
environment there wouldn't be a need to change but in a unstable environment
that changend "quickly" animals would have to adapt to the new circumstances
in order to survive. So was the Campanian actual a verry unfavourable period
for the dinosaurs instaead of a good one as dr. Norman says in his book
Dinosaurs?
