Rulerofprehistory

250 million years ago -The First Atomic Era. Earth is far more radioactive than today.  Giant organisms rule the planet, feeding on the radiation.  Known species include Legendary Godzilla, Skullcrawlers, Shinomura, & Jinshin-Mushi.  Necrotherius comes to Earth and causes the Permian extinction, forcing survivors into the Hollow Earth. He is supposedly repelled by Legendary Godzilla according to myths, but more research is required. 66 million years ago -King Ghidorah arrives at Earth and causes the Cretaceous extinction until Earth creates Mothra and Battra to drive him out.  Some species, like Godzilla, Rodan, Anguirus, etc., survive by escaping into the Hollow Earth. 70,000 years ago -The Elias come to Earth and create “The Children” (Garugaru, Barugaron, Dagahra, Shiigan, Vagnosaurus, Jyarumu, Balkzardan, & Razin) to regulate the planet's climate to suit their needs.  Battra wipes out this civilization in retaliation, but is stopped by Mothra and is sealed away.  Belvera
