Any creature whose name means 'terrible claw' is one that should be given respect. That's what you have there... a Deinonychus.

- Dr. Kajal Dua

Deinonychus is a genus of dromaeosaurid dinosaur that originated from Early Cretaceous North America. A close relative of Velociraptor, the Deinonychus bred by InGen can be distinguished by their head crest and distinctive red coloration. Deinonychus are unlocked by the Hammond Foundation on Isla Tacaño.


Deinonychus was not planned to be a featured dinosaur in the original Jurassic Park on Isla Nublar, and no Deinonychus populations were reported by InGen on either Nublar or their Site B facility on Isla Sorna in 1996.[1]

However, a promotional art piece by Claire Dearing's Dinosaur Protection Group listing both extinct and extant species of dinosaur on Isla Nublar, listed Deinonychus as apparently extinct, implying that the animal had previously been cloned for Jurassic World.[2]

A close relative of Velociraptor, Deinonychus has a rooster-like comb on its head, as well as another fleshy ridge along its tail. It also has a short skull than Velociraptor, with large pronounced eye ridges. The base genome has reddish-grey skin with a dark band along its body and around its eyes.


Much like Velociraptor, Deinonychus is a swift moving predator. Despite their similarities, they cannot coexist and will fight each other. In fact that genera seem extremely antagonistic towards one another and will hunt down the other even if food is available. Who is the victor in the battles can vary, though unmodified the Velociraptor has slightly higher base stats and may have an advantage. However Deinonychus can reap a higher benefit from some genome splices, meaning a heavily modified Deinonychus will be exponentially more dangerous than the base creature.

Also like Velociraptor, Deinonychus are social animals and will rapidly lose comfort and turn antagonistic if denied a pack. A bare minimum of 3 individuals per paddock can reduce rampages though a number of 4 to 6 is recommended. If given space and numbers, Deinonychus can be considered a more docile alternative to Velociraptor.


Deinonychus has been found in both the Cedar Mountain and Cloverly Formations. A relatively medium-sized dromaeosaur, it was also one of the earliest of its family, yet showed advanced features that would be passed onto later theropods of the Coelurosauria line; such as a stiffened tail to keep the dinosaur steady while running and stereoscopic vision so it could gauge distances.

Deinonychus was somewhere in the middle of the food chain. It lived in packs and preyed on small to medium-sized herbivores, such as Tenontosaurus, and Zephryosaurus, but avoided the large sauropods such as Astrodon and Sauroposeidon. It may have also taken on armored dinosaurs such as Sauropelta when in packs. It also lived alongside much larger predators, such as the apex predator at the time, the Acrocanthosaurus.


  • In real life, Deinonychus was only about 3 meters long, 0.87 meters tall at the hip, 1.2 meters at the head, and was also quite likely feathered. Both the comb and tail ridge present in Evolution is only artistic license. Deinonychus only had a long skull with no obvious eye ridges in real life. The look of the in-game genus is due to the developers using older reconstructions which had shorter and taller skulls to further differentiate it from Velociraptor.
  • The design for this dinosaur resembles the Green Basilisk (Jesus Christ lizard), especially in its Rainforest and Taiga colors.
  • In the Jurassic Park novel canon, Deinonychus is considered to be synonymous with Velociraptor, and also precisely, primarily used as the basis of the raptor's larger-than-life size.
  • In the The Lost World: Jurassic Park (console game), Deinonychus briefly appears as an enemy. It bears a resemblance to the Velociraptor that appeared as well, only different in colors. Oddly, it is smaller than the Velociraptor, instead of ultimately being bigger as in real life. They are also called "Deinon-Raptor", likely to differentiate them from the Velociraptor.
  • In Jurassic Park III: Park Builder, Deinonychus briefly appears and can be recreated from Paleo-DNA.
  • Deinonychus was originally intended to be in Jurassic Park Operation Genesis, but was ultimately cut, due to time constraints.
  • The Deinonychus also shares some similar sounds with the Dilophosaurus in the game.
  • Originally, the Deinonychus in the game was ultimately confused with Guanlong, that was also precisely in no way similar to the Deinonychus.
  • It was also once commonly thought that in the Jurassic Park film canon, much like the novel canon, Deinonychus was synonymous with Velociraptor and was precisely, primarily the basis for the Velociraptor, until it was proven that both Deinonychus and Velociraptor in the film canon, due to both the Holoscape and DPG List, are precisely separate genera.
