Dromaeosauridae

Dromaeosauridae is a family of feathered theropod dinosaurs that includes Velociraptor and Deinonychus. Its members are known for enlarged sickle-shaped claws on their second toes.

Theropoda: A major group of mostly bipedal dinosaurs that includes birds and many carnivorous species. Dromaeosaurids are theropods, sharing this group’s ancestry and basic body plan.
Velociraptor: A small dromaeosaurid dinosaur known from Late Cretaceous deposits in Mongolia and China. It is one of the best-known members of the family.
John H. Ostrom: An American paleontologist whose research on Deinonychus reshaped interpretations of dinosaur activity and bird ancestry. His 1960s work brought dromaeosaurid anatomy to the center of dinosaur debates.
Troodontidae: A family of small to medium-sized maniraptoran theropods closely related to dromaeosaurids. Troodontids share close ancestry but differ in skull, teeth, and foot anatomy.
Maniraptora: A group of theropod dinosaurs that includes birds and several close non-avian relatives. Dromaeosaurids belong within this branch of bird-line theropods.
Deinonychus: A medium-sized dromaeosaurid dinosaur from Early Cretaceous North America. Its anatomy helped establish the family’s distinctive sickle-clawed form.
Robert T. Bakker: An American paleontologist who argued that many dinosaurs were active, warm-blooded animals. He helped popularize the energetic, birdlike interpretation associated with Deinonychus.
Dromaeosaurinae: A subfamily of dromaeosaurids that includes robust forms such as Dromaeosaurus. It is one major branch within the family, contrasted with more lightly built relatives.
Feathered dinosaur: A dinosaur with feathers or feather-like integument, structures preserved directly in many fossils. Feather evidence places dromaeosaurids within the broader history of dinosaur feathers.
Microraptor: A small, feathered dromaeosaurid genus from Early Cretaceous China, with long feathers on all four limbs. Its exceptional fossils reveal a winged body plan within the family.
