Deinonychus antirrhopus 2014 by DELIRIO88 Deinonychus antirrhopus 2014 by DELIRIO88
Pencil on A3 Paper + Photoshop filters, real size silhouette and little description

First Paleoart of 2014.
I chose for the third time Deinonychus antirrhopus 'cause it's the perfect subject on which to test the knowledges that I learn in this years about the paravians' anatomy and the way to portray them in paleoart.

Here you can see how much is changed my perception about this animals:

Some notes about this art:
Based on the skeletal reconstruction [link] made from Mr. Hartman. :iconscotthartman:.

I really love the :iconfreakzter:'s raptor pose…, so I decided to use it for my work, fixing it with massive anatomy corrections.

About plumage:

Quoting the really great :iconewilloughby: "The feathery toes, while not terribly unique due to finds like Anchiornis, are loosely based on Matt Martyniuk's new post on dinosaur foot scales, which indicates that scutes may have evolved from feathers, rather than the opposite."

Other reference took from the usefull blog of Andrea Cau, Theropoda…

EDIT: Huge update. Digital version of my work with massive fix of arms. Color based on a golden eagle.

Deinonychus ( /daɪˈnɒnɨkəs/ dy-non-i-kəs; Greek: δεινός, 'terrible' and ὄνυξ, genitive ὄνυχος 'claw') is a genus of carnivorous dromaeosaurid dinosaurs. There is one described species, Deinonychus antirrhopus. These dinosaurs could grow up to 3.4 meters (11 ft) long and lived during the early Cretaceous Period, about 115–108 million years ago (from the mid-Aptian to early Albian stages). Fossils have been recovered from the U.S. states of Montana, Wyoming, and Oklahoma, in rocks of the Cloverly Formation and Antlers Formation, though teeth that may belong to Deinonychus have been found much farther east in Maryland.
Paleontologist John Ostrom's study of Deinonychus in the late 1960s revolutionized the way scientists thought about dinosaurs, leading to the "dinosaur renaissance" and igniting the debate on whether dinosaurs were warm-blooded or cold blooded. Before this, the popular conception of dinosaurs had been one of plodding, reptilian giants. Ostrom noted the small body, sleek, horizontal posture, ratite-like spine, and especially the enlarged raptorial claws on the feet, which suggested an active, agile predator.
"Terrible claw" refers to the unusually large, sickle-shaped talon on the second toe of each hind foot. The fossil YPM 5205 preserves a large, strongly curved ungual. In life, archosaurs have a horny sheath over this bone which extends the length. Ostrom looked at crocodile and bird claws and reconstructed the claw for YPM 5205 as over 120 millimetres (4.7 in) long. The species name antirrhopus means "counter balance", which refers to Ostrom's idea about the function of the tail. As in other dromaeosaurids, the tail vertebrae have a series of ossified tendons and super-elongated bone processes. These features seemed to make the tail into a stiff counterbalance, but a fossil of the very closely related Velociraptor mongoliensis (IGM 100/986) has an articulated tail skeleton that is curved laterally in a long S–shape. This suggests that, in life, the tail could bend to the sides with a high degree of flexibility.
In both the Cloverly and Antlers formations, Deinonychus remains have been found closely associated with those of the ornithopod Tenontosaurus. Teeth discovered associated with Tenontosaurus specimens imply they were hunted or at least scavenged upon by Deinonychus.
