The Cretaceous Dinosaur

By:Malena Yocum

Major geologic events in the time period

During the Late Cretaceous time period the global climate was warmer than today's climate. No ice existed at the Poles.Dinosaurs migrated between the Warm Temperate and Cool Temperate Zones as the seasons changed..Cretaceous period (krĬtā´shəs), third and last period of the Mesozoic era of geologic time (see Geologic Time scale, table), lasting from approximately 144 to 65 million years ago. The Cretaceous was marked, in both North America and Europe, by extensive submergence of the continents. Changes both in the earth's surface and in its flora and fauna brought the Mesozoic to a close.

Things that you would need

What was the environment like

The environment during the cretaceous period was warm with ice-free poles. Back then, there were mostly dinosaurs roaming the earth, but other mammals we see today were starting to appear.

Some things that the travelers might want to see

What dangers might travelers face

They might face danger's like the dinosaurs trying to eat them and that they might not be able to find a food and how will they make weapons.

Living plants and animals in the Cretaceous time period

One of the hallmarks of the Cretaceous Period was the development and radiation of the flowering plants. The oldest angiosperm fossil that has been found to date is Archaefructus ljiaoningensis, found by Ge Sun and David Dilcher in China. It seems to have been most similar to the modern black pepper plant and is thought to be at least 122 million years old.

It used to be thought that the pollinating insects, such as bees and wasps, evolved at about the same time as the angiosperms. It was frequently cited as an example of coevolution. New research, however, indicates that insect pollination was probably well established before the first flowers. While the oldest bee fossil was trapped in its amber prison only about 80 million years ago, evidence has been found that bee- or wasp-like insects built hive-like nests in what is now called the Petrified Forest in Arizona.
