We no longer see dinosaurs as the same oafish, tail-dragging monsters that trudged through King Kong Some odd-looking remains were discovered on a fossil-hunting trip through Montana in Yale paleontologist John Ostrom quickly deduced that these were the bones of a carnivorous dinosaur that belonged to the theropod suborder. Instead, its light frame, counterbalancing tail, and huge, hooked claws betrayed an active lifestyle. Perhaps it was even warm-blooded.

Deinonychus facts

Deinonychus was one of the cleverest dinosaurs when comparing its brain size to the size of its body. Find out all about it. Pictures, diet facts, size and where it lived. And whether having feathers meant it could fly! Deinonychus was a feathered dinosaur with terrible claws - hence its name. It had three claws on its 'hands' and a large talon on the back legs. It was a carnivore or meat eating dinosaur. This dinosaur was really like a bird. It had feathers but was not a flying dinosaur and couldn't fly. Instead the feathers could have helped to streamline it for running, or kept it warm. However, it probably wasn't particularly fast compared to other dinosaurs. The talons on its hind legs could retract when the dinosaur wanted, so it could tuck them in for running and walking. Then it could bring them out again later to rip apart food. It has a dinosaur classification of Theropod.

Below, you'll discover 10 fascinating Deinonychus facts.

It's not nearly as well-known as its Asian cousin, Velociraptor, which it played in Jurassic Park and Jurassic World , but Deinonychus is far more influential among paleontologists--and its numerous fossils have shed valuable light on the appearance and behavior of raptor dinosaurs. Below, you'll discover 10 fascinating Deinonychus facts. The name Deinonychus pronounced die-NON-ih-kuss references the single, large, curving claws on each of this dinosaur's hind feet, a diagnostic trait that it shared with its fellow raptors of the middle to late Cretaceous period. The "deino" in Deinonychus, by the way, is the same Greek root as the "dino" in dinosaur, and is also shared by such prehistoric reptiles as Deinosuchus and Deinocheirus. In the late 's and early 's, the American paleontologist John H. Ostrom remarked on the similarity of Deinonychus to modern birds--and he was the first paleontologist to broach the idea that birds evolved from dinosaurs. What seemed like a wacky theory a few decades ago is today accepted as fact by most of the scientific community, and has been heavily promoted over the last few decades by among others Ostrom's disciple, Robert Bakker.

Carnivore , Early Cretaceous , Theropod. Regan Douglas. October 20, In the grand tapestry of prehistoric life, few creatures capture our imagination quite like Deinonychus. Its unique combination of physical attributes and behavioral traits paints a vivid picture of a world long lost to time. The Deinonychus is a testament to the power of evolution, a creature perfectly adapted to its environment and its role within it. Its sharp, retractable claw, agile body, and keen hunting instincts made it a daunting presence and represented the raw, untamed beauty of nature in its most primal form. This name is a reference to the large, sickle-shaped claw found on each of its hind feet, a distinctive feature that set it apart from other dinosaurs of its time. In terms of taxonomic classification, Deinonychus belongs to the group Theropoda—a group of bipedal dinosaurs that includes both carnivorous and omnivorous species. Within this group, it is classified under the family Dromaeosauridae which are known for their bird-like characteristics and agile hunting abilities.

Deinonychus facts

Deinonychus is a dinosaur which lived about million years ago during the Cretaceous Period. It was first discovered in near the town of Billings, Montana by Barnum Brown. Since then, fossils have been found in parts of Wyoming and Oklahoma as well. When Deinonychus lived, it could reach a hip height of 3 feet, a length of 12 feet and a weight of approximately pounds. The similarity of this dinosaur to a modern bird caused scientists to develop the theory that birds are indeed descendants of dinosaurs — a theory that was first postulated during the late s. It is believed by some scientists that these dinosaurs actually did have feathers like modern birds. Although there is no solid proof that Deinonychus had feathers, the finding of Velociraptor feathers may be enough proof to postulate that these dinosaurs also had feathers. What is known about these dinosaurs however, is they had all the tools they needed to be aggressive predators. Not only did they have a bite force which was probably a little less than a modern crocodile, but they also had those formidable razor sharp claws on their hind feet.

The Dinosauria 2nd ed. A specimen of Velociraptor has been found with quill knobs on the ulna. It was qute short - about the height of an average adults' elbow when standing. The Mosasaur. The Mountain Geologist. Velociraptor antirrhopus Ostrom, Paul, In Weishampel, D. An examination of these unprepared blocks by Gerald Grellet-Tinner and Peter Makovicky in revealed an interesting, overlooked feature. Their length was 3. Quill knobs are where the follicular ligaments attached, and are a direct indicator of feathers of modern aspect. Farke, Andrew Allen ed. By the way, there's no chance that Deinonychus, or any other dinosaur, was smart enough to turn doorknobs, and it almost certainly didn't possess green, scaly skin, either. Long, interweaving rods extended from most of its tail vertebrae, which made the appendage abnormally stiff.

The subfamily name Velociraptorinae was first coined by Rinchen Barsbold in [37] and originally contained the single genus Velociraptor. Contents move to sidebar hide. In contrast, Deinonychus antirrhopus stretched over 11 feet from end to end and sported a much taller snout. Join our community of di-know-it-alls and support our show on Patreon. Several Tenontosaurus dinosaur fossils show bite marks from Deinonychus. Instead, its light frame, counterbalancing tail, and huge, hooked claws betrayed an active lifestyle. The Mosasaur. To date, no direct evidence has been adduced for Deinonychus having feathers, but the proven existence of other feathered raptors such as Velociraptor implies that this larger North American raptor must have looked at least a little bit like Big Bird--if not when it was fully grown, then at least when it was a juvenile. Please read my advertising disclosure. An examination of these unprepared blocks by Gerald Grellet-Tinner and Peter Makovicky in revealed an interesting, overlooked feature. As the data suggests that Deinonychus had a more typical reptilian set of life stages, the examinations also have been stated to indicate a lack of complex, cooperative social behavior found in mammalian terrestrial pack-hunters such as wolves.
