This raptor is Dromaeosaurus, a hunter and scavenger from the Late Cretaceous.
— Allen, about Dromaeosaurus

Dromaeosaurus (name meaning "Swift Running Lizard") is a genus of dromaeosaurid theropod dinosaur that originated during the Middle Cretaceous period in what is now North America. Measuring 2 meters long, Dromaeosaurus was very similar to is close relative Velociraptor, which happened to be living at the same time, however, on the other side of the world.

In the Series 2 finale "Fall of a Kingdom Part II: The Return of the King", a pack of Dromaeosaurus was brought to the park from Late Cretaceous Montana 65 million years ago. The pack resides in their own pen at Raptor Peak alongside their other relatives.


Era & DiscoveryEdit

Dromaeosaurus lived in North America during the Middle to Late Cretaceous period from 90–65 million years ago, living up to the last days of the dinosaurs. It died out with the other dinosaurs at the end of the Cretaceous.

The first known Dromaeosaurus remains were discovered by paleontologist Barnum Brown during a 1914 expedition to Red Deer River on behalf of the American Museum of Natural History.

Physical AttributesEdit

Dromaeosaurus was small compared to other members of its family. They stood 3–4 feet (1–1.4 m) tall at the hips, measured 6 feet (2 m) long and weighed less than 45 kilograms (100 lbs). A part-time scavenger of the Late Cretaceous, these predators were small but were still members of the raptor family. As such, they were lethal dinosaurs.

Dromaeosaurus was unique among other dromaeosaurs. Unlike other medium-sized dromaeosaurs such as Velociraptor, Dromaeosaurus had a short, massive skull, deep mandible, and robust teeth, which seem to be made for crushing and tearing meat due to the heavy wear marks on them. 

It had a very stiff tail, like all dromaeosaurs, and it had a huge, sickle-like claw on its second toe, most likely used to stab the throat of its prey. It was the first non-dubious dromaeosaur found and is the type genus. It is closely related to such large dromaeosaurs as Utahraptor.

Behavior & TraitsEdit


Dromaeosaurus pack

Like all members of the raptor family, Dromaeosaurus hunted in packs, from numbers of as many as 3-12 individuals. And like wolves as well as other raptors, the pack was always lead by an Alpha. Using darkness, these pack hunters tried to unsettle herds of plant-eating dinosaurs and isolate the youngsters, even herbivores as big as Torosaurus.

Even alone, a single Dromaeosaurus hunted other small dinosaurs and even tried to feed on T. rex nests.



  • The sound effects of Dromaeosaurus are that of coyote, lynx, and vulture.
  • Dromaeosaurus was the last dromaeosaur brought to the park.
  • This dinosaur gives its' name it to the entire family of the Dromaeosauridae, that being all of the 'Raptors'.
  • Dromaeosaurus is now known to have feathers.
