Prehistoric World

Chapter 6: Mammals didn't always rule

This is (Y/N) (L/N). He/She is a (G) with a dream: a dream to show the world what it was like, once upon a time. Using special technology, he/she plans to go back in time to save some of the most spectacular animals that ever existed. Today, he/she plans to go back and save the animals that rules two continents during the time of mammals. But these weren't mammals. These came in the form of a giant flightless bird, and a giant monitor lizard.

"Phorusrhacos, better known as the Terror Bird, ruled South America for most of the Pleistocene, until North America was connected to South America. It's ancestor Titanis then migrated to North America, where it had competition from animals like Wolves and Saber-Tooth Cats. But this species, Phorusrhacos, went extinct before it met the saber toothed cat, Smilodon. The animals thrived, and were top predator for millions of years.

"And Megalania, the ruler of Australia, during the Pleistocene. It was the largest carnivorous reptile to walk the earth since Tyrannosaurus Rex. Both continents are examples of evolution isolation. Basically they were separated from the rest of the world, so they had a way of like, 'experimenting' with nature. And thus, the Terror Birds and Megalania were born from the evolution isolation." 

Soon, the portal was set up, and (Y/N) headed off to South America, 15 million years ago, with Alice, Steve, and guest zoologist Nigel Marvin.

Here in South America, the land is covered with savannah surrounded by forests. These open areas are perfect for some of the animals that live here. During this time, there are animals called megafauna. These are super sized animals of present day animals. And their first example came sooner than expected.
