Scientists believe that 65,000,000 years ago, a meteorite's crash on Earth killed
off the dinosaurs, but in truth, it split Earth into two parallel universes: The
Earth we know is referred to as "Another Earth" by the residents of the Earth where
dinosaurs were still the superior species, Dino Earth. Overtime, the humanoid
Ryujin (dinosaur people) and Bakuryu (mechanical dinosaur) races came into being on
DinoEarth but were at war with the Evolians, entities that emerged from the meteor.
The two Earths are separate until Asuka, a Ryujin from Dino Earth, arrives on Earth
via a transdimensional portal. However, he is followed by the Evolians in their
Anamolicarus spaceship and the three Bakuryuus under their control. As the Bakuryus
Tyrannosaurus, Ptreranodon, and Triceratops attack Tokyo, a call is sent out to
people who possess DinoGuts and the potential of gaining the power to tame the
rampaging Bakuryu. Together with their Bakuryu partners, the three people
recognized by the first three Bakuryu become Abarangers to protect their dimension
from the Evolians
