  Theropoda
The Theropoda represent one of the two main groups of Saurischian ("lizard-hipped") dinosaurs, the other being the herbivorous Sauropodamorpha.
Theropoda means "beast-feet", a rather inappropriate name; "bird(-like) feet" would have been better.
Included in this group are both small forms (among them the ancestors of birds) and large predators such as Allosaurus and Tyrannosaurus.

Theropoda (thair-uh-PODE-ah) is the suborder of carnivorous dinosaurs.
Theropoda includes the largest carnivore ever to roam the Earth, Tyrannosaurus, as well as the chicken-sized Compsognathus.
Somewhere between the two were the dromaeosaurids, medium-sized predators that ranged from 10 to 20 feet (3 - 6 meters) long and were equipped with disproportionately-large sickle-like claws on their hands and feet.

 Theropoda - EvoWiki
Theropoda ("Beast foot"; Marsh, 1881 sensu Gauthier 1986) are a group of bipedial, mainly carnivorous dinosaurs, and are the common ancestor of, and all descendants of forms closer to Neornithes, than Saltasaurus, making them the ancestors of all birds.
The group flourished during the Triassic, but is today only represented by birds.
The list of autapomorphic characters underwriting holophyly of Theropoda is substantial (from Gauthier 1986, and Weishampel et al.

 Theropod Dinosaurs
Still it's not as exciting seeing a sparrow at your birdfeeder as it would be to see a Tyrannosaurus rex there.
Our knowledge of the evolutionary history of the Theropoda is constantly under revision stimulated by new, exciting fossil finds every year or so such as Mononykus olecranus, a very bird-like theropod found recently in the Mongolian desert, or Giganotosaurus carolinii, a giant theropod probably rivaling the size of T.rex.
In fact, the 1960's discovery and study of the remains of Deinonychus antirrhopus helped to revise paleontology's old vision of all dinosaurs as slow, stupid reptiles, and was a key factor in the onset of the controversial hot-blooded/cold-blooded debate.
