Deinonychus

Deinonychus is a genus of small dromaeosaurid theropod dinosaurs from Early Cretaceous North America, notable for a large, curved claw on each hind foot.

Dromaeosauridae: A family of predatory theropod dinosaurs that includes Deinonychus and Velociraptor. Deinonychus belongs to this family of agile, sickle-clawed theropods.
Dromaeosaurid foot: The specialized foot of a dromaeosaurid, with an enlarged curved claw on the second toe. Deinonychus’s raised, enlarged second toe shaped both its stance and its famous claw.
John H. Ostrom: An American paleontologist who studied dinosaurs and argued that Deinonychus was active and birdlike. Ostrom’s study of Deinonychus helped revive interest in dinosaurs as active animals.
Dinosaur renaissance: A mid-to-late twentieth-century change in paleontology that recast dinosaurs as active, diverse animals. Deinonychus became a prominent example in this reassessment of dinosaur biology.
Theropoda: A diverse dinosaur group that includes living birds and extinct bipedal predators. This broader dinosaur group contains Deinonychus and its dromaeosaurid relatives.
Caudipteryx: A small feathered theropod dinosaur from Early Cretaceous China, known from well-preserved fossils. Its preserved feathers help frame what is inferred, rather than directly known, about Deinonychus’s covering.
Yale Peabody Museum: A natural history museum at Yale University in New Haven, Connecticut. Its collections and exhibits helped bring Deinonychus and Ostrom’s research to public attention.
Bird: A warm-blooded feathered vertebrate belonging to the living dinosaur lineage. Deinonychus’s anatomy helped strengthen arguments linking birds with theropod dinosaurs.
Dromaeosaur: A common name for a member of the predatory dinosaur family Dromaeosauridae. The name captures Deinonychus’s family-level identity as a dromaeosaur.
Deinonychus antirrhopus: The type and best-known species of the dinosaur genus Deinonychus. This species supplies most of the anatomical evidence used to reconstruct the genus.
