Voth
The Voth are an alien of the week race from the Voyager episode "Distant Origin". They are a typical example of how Star Trek writers have no clue how evolution works. The Voth are supposedly the descendants of an advanced species of dinosaurs that fled from Earth to escape the mass extinction event that killed off all of the other dinosaurs. They settled in the Delta Quadrant, where they "evolved" into a very humanoid species.
Voth Technology
Having been space travellers for millions of years, the Voth are technologically quite advanced. They have space ships the size of cities, transwarp drive, advanced cloaking technology (including personal cloaking devices), transporters capable of moving an Intrepid-class starship, and computer-cracking technology capable of breaking Federation computer security in seconds (granted, given the nearly non-existent computer security seen in Trek, this last ability isn't exactly saying much).
