Deinonychus antirrhopus 2015 by DELIRIO88 Deinonychus antirrhopus 2015 by DELIRIO88
A Deinonychus while preparing an ambush.

The observations of the talented Emily :iconewilloughby: about arm-folding here were enlightening, so I decided to create early the 2015 version.
Based on the skeletal reconstruction [link] made from Mr. Hartman. :iconscotthartman:.


About plumage:
The colors are based on the bearded vulture livery, with some variations.
The feathery toes are based on Matt Martyniuk's 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 theropoda.blogspot.it/2013/03/…

----

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.

Love that color scheme. David Silva used that same color scheme for the Velociraptor in his first line of the "Beasts of the Mesozoic" action figures.

Imaigine if the jp raptors d.n.a was spliced with crested vultures instead of african monitor lizards. I did like the concept of dinosaurs genes being mixed with modern animals.

Hey Mr. Svensen. Your work truly inspired me.
I examined various arts, among them there was also yours. I really liked the idea of an animal that you were flattening to the ground ready for the ambush, and I tried to make my own.

Thanks for your visit!

Ha, I was wondering if it wasn't at least partially inspired by mine, but my inner voice of doubt was skeptical. That's pretty cool. (Also amusing that yours is readying for an ambush, while the idea behind mine was that it's puffing itself up to look bigger to a rival.) (I got the idea from a painting by Brian Sibley of two semipalmated plovers displaying to each other.)
