If Deinonychus had feathered fingers and wings, the feathers would have limited the range of motion of the forelimbs to some degree. For example, when Deinonychus extended its arm forward, the 'palm' of the hand automatically rotated to an upward-facing position. This would have caused one wing to block the other if both forelimbs were extended ...

Deinonychosauria is a clade of paravian dinosaurs which lived from the Late Jurassic to the Late Cretaceous periods. Fossils have been found across the globe in North America, Europe, Africa, Asia, South America, and Antarctica, [2] with fossilized teeth giving credence to the possibility that they inhabited Australia as well.

The discovery of the Deinonychus fossils is considered one of the most important fossil finds in history.

Ostrom also suggested that it had hunted in packs.

Red's sister dies, and Red is crippled and defenseless against the smaller dinosaurs. The Deinonychus close in but are driven back by the sudden arrival of the older Utahraptor chick and Red's consort, who defend the nest.

Deinonychus is a genus of carnivorous dromaeosaurid dinosaur that existed during the Early Cretaceous. It contains only a single species, D. antirrhopus . Fossils of the 3.4 meter (11 ft) long dinosaur have been recovered from the U.S. states of Montana , Wyoming , and Oklahoma , though teeth attributed to Deinonychus have been found as far ...
Dromaeosaur research was fairly quiet until the 1960s, when John Ostrom described the new genus and species Deinonychus antirrhopus. [2] This discovery played a major role in setting off the Dinosaur Renaissance because Deinonychus was obviously a vigorous, active animal, and exhibited characteristics linking it to the origin of birds.
