Scientific classifications of things I find tend to be...counter-intuitive to the layman, and often unhelpful. Such as tomatoes not being a vegetable, even though for any practical use of them considering them a vegetable is probably more useful.BeetleManiac said:I actually worked at the Carnegie Museum of Natural History for a year as a guide. I can answer a few questions about dinosaurs if anyone is interested.
For example, the only dinosaurs that had feathers were from the order Theropoda. Theropods were bipedal and typically carnivorous. It includes raptors, allosaurs, carnosaurs, tyranosaurs, etc. Theropods were also distinguished by having a V-shaped hip bone that allowed for faster running. This hip formation is called saurischian meaning "lizard-hipped" and dinosaurs with C-shaped hip bones were called ornithischian or "bird-hipped." Which is ironic because birds evolved from Theropods, and more specifically the proto-dromaeosaurs. Proto-dromaeosaurs were the direct answers of the raptors that we all know and love such as velociraptor, utahraptor and deinonychus.
Archaeopteryx, sometimes referred to as "the first bird," appeared in the fossil record during the Jurassic period and is among the earliest known dinosaurs capable of flight. By the Cretaceous period, early true birds had appeared though many bird-lizards were still flying around.
It's also a common fallacy that pterosaurs like pteranodon and ramphorhynchus were also dinosaurs. In fact, they were cousins to the dinosaurs who split off sometime in the mid to late Triassic period somewhere in the neighborhood of 240 million years ago. Dinosaurs, pterosaurs and crocodillians are all members of the larger archosaur group.
This means that the only modern descendants of the archosaurs are birds, alligators and crocodiles. And yes, birds are dinosaurs in the same way that humans are primates.
A horrifying thought to have door to door raptors.Dr. McD said:Velociraptors were never terrifying in the first place, I believe the dinosaur you're thinking of is a "Utahraptor".Programmed_For_Damage said:I'm guessing a lot of scientist have long suspected that dinosaurs had more in common with birds than reptiles, hence the "raptor" in "velociraptor". That said a velociraptor covered in feathers is more laughable than terrifying... until it rips your intestines out.
Unlike the person you're talking to, I am not in any way an expert. However, in the aforementioned videos I've seen, the term "non-avian dinosaur" seems the favored one when referencing the "traditional" dinosaurs; i.e., the ones that went extinct in the K-Pg event. It is a bit clunky, but it's functional when talking about this from a scientific perspective.Saelune said:Scientific classifications of things I find tend to be...counter-intuitive to the layman, and often unhelpful.

Slight tangent aside, what then makes something a "Dinosaur"?
Its just...re-labeling things on a cultural level is so difficult...hell, we call movies movies...cause they move...get it? And we use plenty of out of date tech and concepts as symbols cause we're used to them. Most symbols for phones are based on old "Dog-Bone" rotary phones.Riverwolf said:Unlike the person you're talking to, I am not in any way an expert.

I think most of us did.Casual Shinji said:Fuck the feathers.
Sorry, but I grew up on awesome dinosaurs.
And seeing as we'll never see an actual dinosaur,
and thus will never have concrete proof that any of them except perhaps the smaller ones had any,
I'm secure in holding to my guns that these things looked rad and not pathetic.
Funny thing about the "losing their feathers when they grow up theory." for T. rex, From what I've heard feathers are highly evolved scales as such they don't really have scales under them. So if that theory is true they would look less like dragon and more like a plucked chicken.Riverwolf said:(Keep in mind, this does not 100% confirm the most controversial set of feathers, that of the t-rex. While they most likely had some kind of feathers, which could easily just mean a few bristles here and there like with elephant fur, childhood is still mostly safe there.)
