Forget the gene splicing of Jurassic Park — the best dinosaurs in science fiction are hyper-evolved reptosapiens or confused, time-displaced beasts. Here are 20 fantastic saurians who just wouldn't go extinct.

Dinosaucers (1987)
This 1980s cartoon was about two warring factions of alien dinosaurs who come to Earth to air their grievances or something. Along the way, the Dinosaucers (the good guys) recruit a gang of confused 14-year-olds to be their sidekicks. The kids were roundly useless, but it wasn't entirely their fault. If an allosaurus in body armor flies in from the troposphere and asks you to join his secret club, you really don't have a say.

To the show's credit, the theme song was one of the best of the 1980s cartoon arena rock anthems. It's like Stan Bush's "The Touch" but with only one lyric.
