Recent evidence suggests that all dromaeosaurs (including both Velociraptor and Deinonychus) had feathers. Also, a Velociraptor has a long skull, nothing like in this picture. This does look like a Deinonychus.
Yes, I'm sure. While there is no direct evidence that Deinonychus in particular had feathers, there is also no evidence to prove otherwise. And since many of its close relatives (such as Velociraptor) definitely had feathers, it is reasonable to assume that Deinonychus had feathers too.
Just kidding. But seriously, where did you get that info? I talked to an actual palaeontologist just the other day, and he said that, according to the most recent evidence, all raptors (if not all theropods) had feathers.
A beak is not made of bone and renders teeth obsolete. Just because he had feathers doesn't mean he was a bird. Although it makes him look friendlier and more MLP-like, it is prehisotorically () inaccurate. I mean, if you can find something as obscure as feathers in ancient fossils something like a beak should be rather prominent, aye? Furthermore, no kind of beak has been found on any of the related species, like Micro-, Utah- and Velociraptor. He was definitely a dinosaur, and dinosaur were not at all friendly predators.
Hmm, I guess I would have made a bad biologist. What is a beak made of then? Enamel or keratin or something? Do raptors fall anywhere along the line of ancestors to modern birds, or are they a separate branch entirely?
Sorry for the questions, I missed out on biology in my youth.
It is made of keratin. And for the question whether he is an ancestor of the birds, let's go to the systematics bubble.
The Deinonychus is part of the group of the theropoda and the sub-group of Paraves, then branching of into the family of and finally ending in the group of Dromaeosauridae, where all our beloved Raptors and the deinonychus-species belong to.
Birds (Aves) branch of as early as the group of Paraves, so while they definitely share the same ancestry, they do not share the same family. So no, they are not the direct ancestors of birds, they're their great-grand Uncles.
Here's a recent reconstruction of what he might have actually looked like: [link]
As you can see, you're not very far away, it's just that Deinonychus doesn't have a beak. That's all.
I remain convinced that dromeosaurs (like velociraptors, deinonychi, and utahraptors) were smarter and more committed predators than maniticores. That doesn't mean Fluttershy won't stare the dino down, but the raptor will make an effort to eat her first.
