Jurassic Legacy

In the year 1985, dinosaurs were discovered in North America, then in Europe, and soon the prehistoric animals were everywhere. No one knows how they came back, all they could think about was survival. Cities were overrun by Utahraptors and Dilophosaurus. Roadways disabled by wandering Triceratops and Maiasauras. The world powers were helpless to stop the prehistoric wildlife as they reclaimed the Earth.
