The Vita-Ra (alt. "vaitara" or "fita-rha") are a species of sapient maniraptorian dinosaurs I invented a while ago. They evolved on an alternate Earth where the K-Pg extinction didn't occur, and their pre-industrial societies were mostly herding nomads, ocean-goers, and tribal hunters.
Post-industrialism, I tend to depict them as a space-faring race with highly advanced technology, in a multiverse full of intelligent life (both terrestrial and extraterrestrial).
