Dinowars: Kyouryuu Oukoku e no Daibouken is a Super Nintendo game in which two characters, Timmy and Jaime, accidentally time travel to the prehistoric era through their father's lab screen. The pair must retrieve a missing time machine fuse from Neanderthals called 'The Rockies' in order to return home. Along the way, they team up with dinosaur characters, Rex and Tops, to defend the threatened DinoCity.
Timmy and his friend, Jaime go into Timmy's father's lab to watch a movie on the big screen. Little do they know that the big screen is actually a time machine. When Timmy touches the remote they are both sucked into prehistoric times. Now in order to return home they must reclaim a time machine fuse that was stolen by some Neanderthals who go by the name of "The Rockies". The Rockies are also looking to destroy DinoCity, so two dinosaurs named Rex and Tops decide to help out the two human children in their fight against the Neanderthals.
