Theropoda

Extant clade of dinosaurs

Theropoda (from ancient Greek θηρίο- ποδός [θηρίον, (therion) "wild beast"; πούς, ποδός (pous, podos) "foot"]) is one of the three major clades of dinosaurs, alongside Ornithischia and Sauropodomorpha. Theropods, both extant and extinct, are characterized by hollow bones and three toes and claws on each limb. They are generally classed as saurischian dinosaurs, placing them closer to sauropodomorphs than to ornithischians.
