Dakotaraptor was a large, feathered dromaeosaurid dinosaur that lived during the Late Cretaceous period, approximately 66 million years ago. Measuring up to 5.5 meters (18 feet) in length, Dakotaraptor was one of the largest known members of its family, which includes the famous Velociraptor. It had long, strong legs adapted for running and large, curved claws on its feet, particularly a distinctive sickle-shaped claw on each second toe, which it likely used for hunting and gripping prey. Evidence of feather impressions suggests it was partially feathered, possibly aiding in temperature regulation or display. Fossils of Dakotaraptor have been discovered in North America, specifically in the Hell Creek Formation in South Dakota, highlighting its role as a formidable predator in the ancient ecosystems alongside Triceratops and Tyrannosaurus rex.
