Dinoanatotinan small square 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 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
Cretaceous%20scene small square 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
