The Cretaceous Period Began
The first ceratopsian and pachycepalosaurid dinosaurs appeared. Also during this time, we find the first fossils of many insect groups, modern mammal and bird groups, and the first flowering plants.

Anatotitans existed
Its name means 'Giant Duck'. It lived about 67 to 65 million years ago in the Late Cretaceous period.
Anatotitan was a 'bird-hipped' dinosaur from the group known as the duck-billed dinosaurs or hadrosaurs. The front of the jaw formed a long, wide beak, with hundreds of teeth at the back lining the cheeks.
Anatotitan had long, powerful back legs with three hoof-like toes. It had small front limbs, with a mitten-like covering on its hands. It stood on all fours to graze, but it could rear up on -
Tyrannosaurus
The name means 'tyrant lizard'. It is probably the most famous of all the dinosaurs!
Tyrannosaurus lived about 65 million years ago in the late Cretaceous period (not the Jurassic as many people think).
Tyrannosaurus was a fierce carnivore (meat-eater) that stood up to 5 metres tall. It was about 14 metres long and weighed up to 5 tonnes. http://www.kidcyber.com.au/topics/dinoCret.htm -
The Cretaceous Period Ends
The end of the Cretaceous brought the end of many previously successful and diverse groups of organisms, such as non-avian dinosaurs and ammonites. This laid open the stage for those groups which had previously taken secondary roles to come to the forefront. The Cretaceous was thus the time in which life as it now exists on Earth came together. It ended with a BOOM a BOOM big enough to cause mass extinction all ova the waaalllllddddd http://www.scientificpsychic.com/etc/timeline/timeline.html
