Miljonär John Hammond on hakkama saanud võimatu ettevõtmisega - tema palgatud teadlased on avastanud viisi, kuidas kloonida miljonite aastate eest välja surnud sauruseliike. Saurused paigutati üksikule saarele, kus avatakse looduspark. Enne selle avamist kutsub John sinna grupi teadlasi, et kuulda nendepoolset hinnangut. Õnnetuseks saavad saurused oma aedikutest välja ja sellest midagi head juba ei tule.
Five young warriors from the ancient civilization of Dinosaur-evolved Humans are awakened in the present day after 170 million years of suspended animation when their sworn enemy, Bandora the Witch, is inadvertently released from her magical container on Planet Nemesis by two astronauts. The five warriors, the Zyurangers, must summon the power of mechanical-looking deities known as the Guardian Beasts, each modeled after a different prehistoric beast, in order to protect mankind from Bandora's evil forces.
In the present a team of four anthropomorphic dinosaurs, created by aliens, must stop three anthropomorphic velociraptors who want to cause a cataclysm that would speed up global warming and make Earth's climate pleasant for dinosaurs again.
