What if a raptor as big as a car once prowled the ancient floodplains of South Dakota
Meet Dakotaraptor steini, one of the most fearsome predators of the Late Cretaceous. Living around 66 million years ago in what is now North America, this massive feathered dinosaur roamed the Hell Creek Formation just before the extinction event that ended the age of the dinosaurs. At up to six metres long and weighing around 300 to 350 kilograms, Dakotaraptor wasn’t just big, it was powerful, agile, and terrifyingly fast.
This raptor had long legs built for running, a stiff tail for balance, and enormous sickle-shaped claws on its feet, measuring up to 24 centimetres. These claws weren’t just for show. They were hunting tools, perfect for slashing, gripping, and taking down prey. The creature’s bones show quill k***s, a feature that confirms the presence of large feathers. While it couldn't fly, these feathers may have helped with maneuvering during high-speed chases or added balance while grappling prey.
Unlike the smaller Velociraptor made famous by movies, Dakotaraptor was much larger and possibly smarter. Some fossil finds suggest it may have moved in small groups, although whether it hunted cooperatively remains a topic of debate. It likely preyed on smaller dinosaurs, juvenile hadrosaurs, and perhaps even scavenged kills made by larger predators like Tyrannosaurus rex.
Its sleek build, strong muscles, and aerodynamic form made it one of the top predators of its environment. With hollow bones that kept it light on its feet, and sharp, curved claws built for combat, Dakotaraptor was the perfect blend of speed, strength, and stealth.
Strange fact: Despite being one of the largest raptors ever discovered, Dakotaraptor's claw was nearly a third the length of its thigh bone, a proportion unmatched in any other dromaeosaurid, making its foot a weapon of almost surgical precision.
