What dinosaurs are thought to have evolved into birds?

Paleontologists who believe birds evolved from dinosaurs think that the most likely bird ancestors were the small, carnivorous theropods. At least one fossil finding seems to indicate that dromaeosaurs, a subgroup of the theropods, eventually branched into many lines, including birds. This subgroup line also included such dinosaur species as Velociraptor, Deinonychus, and Utahraptor.
