Velociraptor (Velociraptor mongoliensis) and Deinonychus (Deinonychus antirrhopus) are both dromaeosaurid theropod dinosaurs, often referred to as “raptors.” Despite their similarities, there are notable differences between the two species.
Velociraptor primarily lived in Asia during the Late Cretaceous period, about 75 to 71 million years ago1. It was smaller, lighter, and faster than its counterpart, Deinonychus. Velociraptors measured approximately 1.8 meters (5.9 feet) in length, stood 0.5 meters (1.6 feet) tall, and weighed between 15 to 20 kilograms (33 to 44 pounds)2. Their most distinguishing characteristic is their sharp, 6.35 cm (2.5 inches) long sickle-shaped claw on their second toe. They likely used it as a weapon for killing prey.
Deinonychus, on the other hand, lived during the Early Cretaceous period, from around 115 to 108 million years ago3. It was a more robust creature, measuring up to 3.4 meters (11 feet) in length, 1.2 meters (3.9 feet) tall, and weighing between 70 to 100 kilograms (154 to 220 pounds)4. Similar to Velociraptors, they too possessed a sickle-shaped claw, but larger at 13 cm (5 inches) on their second toe. The larger size and strength of Deinonychus, along with its powerful claw, suggest it was a fierce and formidable predator.
While both raptors are bipedal, Deinonychus was more heavily built, with a longer tail for added stability and balance. Additionally, fossil evidence suggests that Deinonychus had more robust arms, which may have been more important during hunting than previously thought5. Velociraptor, conversely, was more agile with lighter bones and a swifter running speed.
Both Velociraptor and Deinonychus played a significant role in inspiring literature and popular culture. Michael Crichton’s 1990 novel “Jurassic Park” featured genetically engineered Velociraptors, which were later brought to life on screen by filmmaker Steven Spielberg in 1993. The Velociraptors in the film were actually based on the size and appearance of Deinonychus and supported ideas from paleontologists like Gregory S. Paul and John Ostrom6. These iconic dinosaur figures continue to captivate and entertain audiences worldwide.
Physical Characteristics
The Velociraptor and Deinonychus, both members of the dromaeosaurid family, were agile and swift predators that roamed during the Cretaceous Period. Although sharing some similarities, there are distinct differences in their physical characteristics that might affect the outcome of a confrontation.
