Survey Mesozoic

At the end of Cretaceous, there was a great mass extinction, which circa 90% of marine- and circe 56% of terrestrial flora falled to prey. The dinosaurs completely extincted. The species of flora  were decimated by approx. 10% of high level species.

A massive meteorite penetation (K/T Boundary) at the peninsula of Yucatanis is to be proved besides volcanic activities, breeding yet another massive degradation of the already degradated ecological system.

Continuous massive volcano activities during the last 500000 years of Cretaceous, leading to a serious decimation of flora and fauna, caused of activities ecological impacts.

The diversity and extension of dinosaurs reached its peaks during Cretaceous.

Little mammals appear.

At the beginning of chalk time first flower plants appear, leading to a considerable intervention in ecology.

The sourpods reached their peak Jurassic.
