Deinonychus (/ d aɪ ˈ n ɒ n ɪ k ə s / [1] dy-NON-ih-kəs; from Ancient Greek δεινός (deinós) 'terrible' and ὄνυξ (ónux), genitive ὄνυχος (ónukhos) 'claw') is a genus of dromaeosaurid theropod dinosaur with one described species, Deinonychus antirrhopus.
The discovery of the Deinonychus fossils is considered one of the most important fossil finds in history. [22] [24] Deinonychus was an active predator that clearly killed its prey by leaping and slashing or stabbing with its "terrible claw", the meaning of the animal's genus name. Ostrom also suggested that it had hunted in packs.
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. [3]
Additional fragments were discovered in the 1940s and were later incorporated into an influential, though inaccurate, skull reconstruction at the American Museum of Natural History. Knowledge of Deinosuchus remains incomplete, but better cranial material found in recent years has expanded scientific understanding of this massive predator.

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 east as Maryland.
Bakker's drawings of Deinonychus and other dinosaurs depicted the animals leaping, running, and charging, and his novel artistic output was accompanied by his writings on paleobiology, with his influential and well-known book The Dinosaur Heresies, published in 1986, now regarded as a classic. [83]
