Dinosaurs Go Extinct

Geological / environmental event

Dinosaurs were the dominant life form on Earth for several million years. Then a comet crashes into the Earth, the planet’s climate changes suddenly and dramatically, and the massive reptiles begin to go extinct. Some dinosaurs escape through portals leading across dimensions to places like the other-dimensional Skartaris, and through time to the modern-day Dinosaur Island in the Pacific. Most of those that remain are hunted to extinction by an alien race whose name translates as Hunter/Gatherers; later, this same race returns to Earth and interbreeds with the earliest Atlantean clans, providing a spark of genetic adaptability that will help the Atlanteans survive after their homeland sinks beneath the waves.

Aboard the comet are worms from the planet Venus, who use their ability to dominate the minds of other living creatures to carve out an empire on Earth before the encroaching ice age forces them to return home. Only in the present era does a Venusian worm who calls himself Mister Mind return and attempt to conquer Earth anew.

Soon after the comet, the Beast of Kilimanjaro, a hulking monster possibly created as a war machine in an alien war, begins to rampage across Earth. The meteor that crashed into the Earth did so in the region that will one day become Dakana, Africa. The meteor’s impact infuses the region with the powerful daka crystals, it was later found that this energy has the effect of paralyzing the Beast, trapping it beneath Mount Kilimanjaro.
