  • A mass extinction occurs at the end of the Cretaceous period on Earth when an asteroid impacts the planet, wiping out the dominant reptile superorder, the dinosaurs, amongst others. (VOY: "Distant Origin"; ENT: "Azati Prime")
  • According to the Distant Origin Theory, some of Earth's dinosaurs belonging to the hadrosaur genus survive the mass extinction. Although the dominant reptile superorder was almost wiped out, these surviving dinosaurs continue to develop, likely on a secluded, by now destroyed landmass. Sometime thereafter, they possibly become one of the first interstellar species in the galaxy when they leave Earth and travel to the Delta Quadrant, laying the foundation for the Voth civilization. (VOY: "Distant Origin")
While Dr. Forra Gegen suggests this hypothesis for the origin of the Voth, Cmdr. Chakotay later theorizes that the Voth's ancestors left before the extinction event, the impending catastrophe being what motivated them to do so in the first place.

In DS9: "The Dogs of War", Weyoun euphorically claims that "the Dominion had not surrendered in battle since it was founded ten thousand years ago." However, this statement contradicts what Weyoun said in DS9: "To the Death", when he stated that "the Dominion has endured for two thousand years [...]."
In DS9: "Little Green Men", Nog states that it "took [ten thousand years] to establish the Ferengi Alliance", which implies it dates back to 8000 BC or earlier. This might also imply that Gint, the first Grand Nagus and original author of the Rules of Acquisition lived at this time, if he is considered the founder of the Alliance.
