The Voth are an intelligent, space-faring, bipedal saurian species that the USS Voyager encountered in the Delta Quadrant. The crew of that ship determined that the Voth evolved from Earth's dinosaurs. Apparently millions of years ago the Voth's ancestors survived extinction after a cataclysmic meteor or comet impact, developed space-faring technology and left Earth. The Voth travel around in massive city-ships that are several kilometers long.
