2 to 4 players compete in this roll and move children's game. The object is to be the first dinosaur to move from the prehistoric era to the 21st century with a live dinosaur. Along the way you'll have to fight the other dinosaurs and get past various "earth events". The earth events include "ice ages, volcanoes, earthquakes and meteorites". The game board also features "dino switch" spaces where you get to switch positions with another player's dinosaur and Time warp spaces, where you move ahead or fall back. Players may choose to be a Triceratops, Stegosaurus, Corythosaurus, or an Apatosaurus. Each of the 4 Dinosaurs has a colorful card with overlays. The base card shows the Dinosaur bones, the overlay shows the Dinosaur alive. As you get closer to extinction, you flip over the overlays to expose the fossil bones. For ages 5 and up.
