Related: About this forumFossil of giant feathered 'Dakotaraptor' found in South Dakota
A research team has identified a new giant raptor fossil dating back 66 million years that would have roamed and was found in far northwestern South Dakota.
Named Dakotaraptor, the fossil from the Hell Creek Formation is thought to be about 17 feet long, making it among the largest raptors or dinosaur specimen with wings ever found in the world.
Popularized by "Jurassic Park" movies, raptors are known for being fast, nimble, small dinosaurs with stiff tails and feet equipped with wicked sickle-like claws of 10 inches.
Dakotaraptor would have been too big to fly, but with the feathers it would make it the largest dinosaur found to date with wings
A partial skeleton of the raptor was found in the Harding County, S.D., part of the formation, one of the more intensely studied dinosaur fossil sites that includes parts of the eastern Montana Badlands, northwestern South Dakota and southwestern North Dakota.
The formation's age ranges from about 65 million to 70 million years old and was formed in a delta with a warm and moist climate.

The links are excellent...I'm going to enjoy reading the second one. The Hell Creek formation is a treasure.

Tyrannosaurus rex may have been known as the big guy around the Hell Creek Formation 66 million years ago, but a newly discovered species of raptor would have roamed the region as one of its most lethal predators.
Dakotaraptor stood 6 feet tall at the hips yet moved like a springy, agile sprinter, reaching 30 to 40 mph rivaling today's ostrich. But potential prey caught admiring the 17-foot-long creature's grace stood little chance, as the strong-muscled winged Dromaeosaur boasted a vicious 9½-inch-long killing claw that could make mincemeat out of any herbivore caught in its path, said Robert DePalma, curator of vertebrate paleontology at the Palm Beach Museum of Natural History.
"It had one of the strongest killing strokes in that slashing claw of any raptor known," DePalma said.
DePalma and his research team including University of Kansas paleontologists announced the new species in a study published Oct. 30 by the University of Kansas Paleontological Institute. Dakotaraptor helps fill a gap in body size distribution between the small bird-like Maniraptora creatures and the giant T. rex found in Hell Creek, which spans parts of northwestern South Dakota, southwestern North Dakota, eastern Montana and eastern Wyoming.
The newly discovered species roamed the earth alongside T. rex, the three-horned Triceratops and the duck-billed Edmontosaurus.
"Dakotaraptor coexisted with all of our favorites from our childhoods," DePalma said. "We had no idea that such a cool and lethal creature existed right alongside them. And it was in the ground the whole time. It's amazing."
