Deinonychus! This was my favorite dinosaur in the 1990s (although I used the "Velociraptor antirrhopus" moniker that Greg Paul gave it at the time). Given the role Deinonychus played in sparking the Dinosaur Renaissance and inspiring the Jurassic Park book (and subsequent movies) it's an icon all its own.

My skeletal is based on the material described by Ostrom (e.g. it's not using any of the undescribed material floating around out there). It's therefore a composite of various YPM and AMNH specimens, although I don't think there will be any large surprises about the proportions in this case.

Edit: The most minor of revisions to the silhouette to make this recent skeletal current.

Deinonychus is the cool raptor dinosaur, but sometimes it gets misplace the name into "Velociraptor antirrhopus" back in late 60's or early 70's, just doesn't seem this before inspirations of Jurassic Park book and later to be same title filmed in 1993.

Looks like I have no chores but to making sure this skeletal drawn from both man-sized raptor to turkey-sized raptor.

The name "Velociraptor antirrhopus" was coined by Greg Paul in a paper in Hunteria in 1988 (it also was popularized in his book Predatory Dinosaurs of the World that same year). That book served as inspiration to Crichton for his book Jurassic Park, and it all snowballed from there.

Okay, so this is why the JP popular raptor got it's named from Greg Paul before Crichton's JP book published.

I remember way back when Deinonychus was portrayed with a more standard "theropod" skull. I.E. taller and not as long. Excellent work.

My favorite dinosaur.

Why did people use the moniker? Did he have any evidence for it?

*ScottHartman Mar 22, 2013 Professional Digital Artist

He did present some evidence for it (though it's failed to be convincing over the long haul), even Greg Paul noted that the genus range would be extraordinarily long (50+ million years), but he felt that based on his reworking of the anatomy that it was still justified (it turns out that some of his interpretations were simply in error, while in other ways the two are fairly different).

Nothing approaching a majority (or even a plurality) of paleontologists ever accepted the synonymization of the two, but in a lot of ways this is an example of popular culture simply talking over science. Greg Paul's book Predatory Dinosaurs of the World became the talk of the town amongst well-informed but non-professional dinophiles, popularizing what was otherwise quite an obscure idea he'd published in Hunteria. One of the avid readers of his book was Michael Crichton, who then proceeded to refer to the animal as Velociraptor in the book Jurassic Park (which then carried over to the movies), helping to catapult the name far ahead of Deinonychus, and giving continuing cover to those who wanted to use the name Velociraptor antirrhopus, regardless of what professional consensus was.

I know, I was one of those dino geeks back in the early '90s. Luckily I had some excellent mentors in the profession that taught me early on how to look past media hype.

I've always internally explained the discrepancy to myself by saying the altered DNA of the raptors made them abnormally large - of course, I had to ignore the giant raptor at the dig site.

~Gojira5000 Mar 18, 2013

Funny, compared to Austroraptor and the other dromaeosaurs, Deinonychus is rather vanilla. Especially when it was the dinosaur that essentially kicked off the Dinosaur Revolution age, the most important age in palaeontology since The Bone Wars.

Though considering all the bizarre dinosaurs palaeontology has seen since, I think it's likely less Deinonychus being vanilla and more theropods being so diverse nothing seems unusual about it anymore. That's sort of what happens when you get so many weird and amazing relatives, I guess.

Though I will admit, it is one of my favourites, Dromaeosaurus holding the title of favourite dromaeosaur. Deinonychus, in it's plainess, is actually retro in a way. It's a species which has hardly (if ever) changed dramatically since it was discovered, more then you can say for many other older species. It's sort of a window back to that time in that sense.

Those lines on the tail are interesting; I assume those are tendon connections?

*ScottHartman Mar 18, 2013 Professional Digital Artist

The lines on the tail are extensions of the chevrons and zygapophyses that extend forward and overlap other vertebrae, making the tail quite stiff.
