From Memory Alpha:
Clan Ru
Troodon species transplanted from Earth before the extinction of the dinosaurs who later gained sentience. Efforts at aggressive expansion in the galaxy were thwarted by the Federation. Attempted to alter time, preventing the evolution of Humanity and the formation of the Federation by deflecting the asteroid responsible for the extinction of the dinosaurs. However, this resulted in the Clan Ru developing on Earth and destroying themselves in nuclear wars before reaching the stars. Convinced against changing the timeline when their alternate future is revealed to them.
Troodon dinosaurs always weirded me out I. Artwork because of their big eyes and random art I saw in a sci-fi book imagining a humanoid version.
