Definition of theropod in English:



  • A carnivorous dinosaur of a group whose members were typically bipedal and ranged from small and delicately built to very large.

    • ‘The theropods include such charismatic extinct animals as Tyrannosaurus rex, as well as the only surviving dinosaurs - the birds.’
    • ‘We know that it is a dromaeosaur, a theropod and relative of Velociraptor.’
    • ‘T. rex is a member of a large group of dinosaurs called theropods.’
    • ‘The next largest carnivores were usually dromaeosaurs or other, much smaller theropods.’
    • ‘Some theropods probably ate other dinosaurs' eggs.’
    • ‘Much fossil evidence has been uncovered supporting the idea that birds evolved from a group of bipedal carnivorous dinosaurs called theropods.’
    • ‘Accumulating evidence suggests that living birds are the direct descendants of theropods, a group of meat-eating dinosaurs that walked on two legs.’
    • ‘Just to add an element of confusion, actual birds evolved from the lizard-hipped theropods, not from the bird-hipped ornithischians.’
    • ‘Allosaurus is the most common of the theropods, making up more than 60% of all theropod specimens.’
    • ‘Much has been written about the small, late Cretaceous theropods known as alvarezsaurids.’
    • ‘If no later birds had evolved, Archaeopteryx would be classified as a feathered theropod, assuming we understood feathers in the absence of birds.’
    • ‘Case said the shape of the teeth and features of the feet were characteristic of a group of dinosaurs known as theropods, which includes the tyrannosaurs, as well as all other meat-eating dinosaurs.’
    • ‘Although great size, as well as a great range of body sizes, are among the most familiar qualities of dinosaurs, the early theropods were both small and fairly uniform.’
    • ‘However, these feathered theropods are clearly just one small group of dinosaurs, and if they were all transported to modern times, they are so similar we would put them all in the same small group.’
    • ‘Apparently, however, the jaws of theropods were relatively weaker for their length than those of carnivorans.’
    • ‘Russell reminds readers that we do not know the biogeographic origin of birds, or theropods, or dinosaurs.’
    • ‘The bones of ceratosaurians, like those of all known theropods, are hollow.’
    • ‘Sifting through the collection, they separated out the bones of a theropod, or meat-eating dinosaur.’
    • ‘Hence, we are suggesting that the pattern of lung ventilation during running in non-avian theropods was the opposite of that observed in recent birds.’
    • ‘Dromaeosaurs, a group of small, fleet-footed dinosaurs in the theropod family, are thought to be the closest known relatives of birds.’


1930s: from Greek thēr ‘beast’ + pous, pod- ‘foot’.
