Theropods ('beast foot') are a group of bipedal saurischian dinosaurs.

Although they were primarily carnivorous, a number of theropod groups evolved herbivory, omnivory and insectivory.^[2]

Today, they are represented by 10,000 living species of birds, which evolved in the Upper Jurassic from small feathered coelurosaurian theropods.

Among the features linking theropods to birds are bipedalism, the three-toed foot, a furcula (wishbone), air-filled bones, feathers and brooding of the eggs.
