@@Hoshimaru57 I have a decades old set called K’nexasaurus Rex that moves fairly smoothly as well

[@johnboone9917]

A word about Jurassic Park. Around the time Michael Crichton was writing his novel, a paleontologist (Gregory Paul, I believe) released a paper addressing and partially revising dromaeosaur taxonomy. Specifically, Paul considered Deinonychus to be a junior synonym of Velociraptor, thus renaming it to Velociraptor antirrhopus. Crichton used this paper for his resource material, which is where the confusion stems from.

[@canalsoloparaverunvideodem8451]

it ought to be the other way around, since deinonychus is much bigger than velocirraptor. anyway, even if I'm not a fan of the JP franchise AT ALL, I remember that back in the day I read the book, and then saw the movie, and I always thought they had swapped V with D just to have a larger dinosaur in the film, but kept the name thinking it sounded cooler. I don't recall that anything in the novel suggested velocirraptor to be larger than it really is. this always bothered me from the beginning, the same way that they decided to shrink dilophosaurus just because. I've always found surprising how very often people mention these movies ever since, even in scientific context, I guess they made a profound impression upon fans of a certain generation, an impression to which I was immune. When they were promoting the first JP, they said they had professional paleontologists giving top notch advice and all that, but they actually took many liberties for the sake of dramatism or whatever, and those movies are really, really poor from a cinematographic point of view.

[@c.l.6957]

I was rewatching old YDAW vids and I saw this comment, I just thought I'd back it up with a quote from the book. "Ellie said "but the animal we just saw, the velociraptor- you said it was a mongoliensis?" "From the location of the amber," Wu said. "It is from China." "Interesting," Grant said. "I was just digging up an infant antirrhopus"" -Chrichton 127-128. Crichton specifies the dino in the park is mongoliensis, then incorrectly says antirrhopus is a velociraptor species, then proceeds to write the rest of the book as if mongoliensis is closer to D. antirrhopus size than to chicken size. Great book though.

[@BaronOBeefDip]

@@c.l.6957 In the resource material Chriton used they labeled Deinonychus as Velociraptor Antirrhopus. By the time the movie came out (it could have been earlier) everyone involved knew of the mistake (just like they were aware of feathered dinos) but kept the name because it sounded cooler and was easier to pronounce.

[@MechaShadowV2]

@@canalsoloparaverunvideodem8451 I always had the impression the Raptors in JP (the novel) where oversized, otherwise they wouldn't be that big of a threat. Remember one got hit by a rpg and all it did was wound the dinosaur. As far as the name goes, aside from cooler I've always read that partly why Spielberg stuck with velociraptor was because it was easier to pronounce. Which I really can't argue with, to this day I struggle with spelling deinonychus, let alone saying it.

[@MechaShadowV2]

@@canalsoloparaverunvideodem8451 also I believe somewhere it's mentioned the dilo was a juvenile, and from a cinematic point of view, it's actually pretty well done, it would not have the following it does today. It's ok to not like something just because you don't like it, don't need to make up a reason for not liking it.

[@jaydubya3698]

I'm not a palenotologist, but loved dinosaurs as a kid and still "geek out" on them today. I grew up in the 60s and the 70s thinking the dinosaur images made by Knight were really cool: dinosaurs were slow, "cold-blooded", reptilian, mean, relentless, powerful, dark creatures moving around in primordial swamps, fighting and dying in epic, earth-shaking battles. But then I saw the original and really beautiful Bakker drawing of Deinonychus in the early 80s and it blew my mind: it still had the look of a reptile, but it was a jet-fighter, a Corvette, a sprinting rapier of a predator. A dinosaurian cheetah. It was mind-blowing. Even the name, "Terrible Claw"...so awesome. One can't understate how ground-breaking this find was and how Ostrem really made the connection to birds...very cool. And still is to this day.

[@3asianassassin]

There is another reason deinonychus was confused with Velociraptor in jurassic park. Crichton mixed up his sources for his book, making deinonychus velociraptor arthirropus.

[@jairiske]

Deinonychus is in the same family of velicoraptor

[@eewweeppkk]

Not exactly. Crichton actually knew that his velociraptors were deinonychuses, and its mentioned in the dialogue between characters _within_ the book itself. They (inGen) chose to use velociraptor because it was more viscous sounding.

[@milyokolarov8675]

I think also because its much easier to say aswell

[@thetwobros9580]

He never mixed up his sources lmfao. Deinonychus Arthirropus was also called Velociraptor Arthirropus. In the books, its directly adressed why the raptors are so large and are called raptors instead of Deinonychus. Just read the book or watch a video on it, but get something straight. Crichton did not mess up his sources

[@verde7595]

The Creator And it used to literally be called Velociraptor antirrhopus until it was given its own name but technically that's still inaccurate

[@locomotivefaox]

It’s actually true that it was based by this, the author of jurassic Park had professionals help him model them after deinonychus

[@coopercobb8867]

"About the size of a horse" *labeled 23 feet long*

[@DoopDoopDoopDoop]

I love how he said its hands are pretty accurate because they are faced inwards, unlike in some movies and ark.

What evs

[@m3ntallyd3fficient11]

Dako I know Im late but considering the raptor in ark is a fucking UTAHRAPTOR, yeah, id say its a kinda inaccurate representation of an animal it is not. And Im pretty sure he said art not ark. And for the most part ark is realistic and accurate, aside from the giganotosaurus being bigger than the trex, even though in real life they were pretty closely sized. What else is inaccurate about ark.

[@maximaldinotrap]

The devs of Ark actually did their research and decided to screw it over in favor of rule of cool and other stuff.

[@eewweeppkk]

No, Ark is not very accurate whatsoever. Even though their raptor is based on Utahraptor, it is still extremely inaccurate. I still like the game, and the developers _know_ that its not accurate. The game is meant to be fun and cool, not accurate and educational, and they 100% know this. They tend to grossly exaggerate size, not just on the giganotosaurus but other animals as well. And they tend to exaggerate features as well, to make them stand out from each other more. For example, Kaprosuchus, being a crocodillian, probably couldn't leap 200 feat horizontally. But they needed it to stand out from the sarcosuchus, so they just posted that onto it.

THAT INTRO WAS SICK

[@crowbrained]

I'd love to hear about Utahraptor, they're my favorite.

[@firesighnavatar3283]

I know I'm a million years late but I always have to comment when it comes up... the Jurassic Park raptors were in fact based on Utahraptor. In one of the features on the DVD set I have they talk about how they hesitated to make the raptors as big as they did because they had no precedent for a dromeosaur of that size. However, WHILE THEY WERE FILMING Utahraptor was dug up and one of the archaeologists on that team called up the consultants for the film and they then went forward in making it as big as they did. Utahraptor wasn't described officially until later, but that doesn't mean the community wasn't aware of it.

[@RavensbladeDX]

I gotta agree with everyone! This series rocks! Do Spinosaurs!

[@phatpat63]

I feel like saying that it had a tail fan because Microraptor had one is like saying a Lynx must have a mane, because you found a Lion with the mane preserved. There's been some serious over-correction in giving _every_ dinosaur flamboyant feathers just because they were far more bird-like than people once supposed.

[@thisisnotharvey]

Honestly, when I draw a sort-of crest on a Deinonychus, it's really just artistic-liberaty. When i draw dinosaurs I try to keep it realistic, but a flat, pigeon-like head looks to bland IMO

[@mynamewhat4437]

yee

[@gladiusbladeofthenorth9939]

ThisIsNotHarvey yee

[@Raisin_Udongein_Inaba]

When I draw dinosaurs, I make sure to make crests and colorful scales/feathers for males. The flat, bland heads are for females

[@jek__]

the opposite of hypertrophy would be hypotrophy. The two prefixes are used opposite of each other in instances where there is a scalar difference between an above position and a below position. Sometimes also used to describe size. I think the a- prefix doesn't have an opposite, it just negates what it comes before, so the opposite of atrophy should be trophy, which, if hypertrophy is overgrowth and hypotrophy is undergrowth, then trophy could mean the presence of a grown body part in the first place. Which would mean atrophy should mean the complete loss of a body part, but english isn't a constructed language lol

[@JedRobby]

I have an original 1978 national geographic magazine with a large segment on his thoughts on deinonychus. It features a drawing that is way ahead of its time for an animal discovered in the 60s. I mean its not feathered but its a really good image of the animal.

[@williamsparks1521]

Man part of me wants to send you what I consider one of the worst examples of a velociraptor toy I have ever found. It not only suffers from the usual problems (like no feathers and wrong arm positions etc) but I am thinking it is a recycled sculpt of some kind. This velociraptor toy has the head of a herbivore. It has a beaked mouth with no teeth and cheeks. Makes me think of really old terrible iguanadon reconstructions and I wouldn't have guessed it was a velociraptor if it wasn't for the toe claw and the text on the belly claiming that is what it's suppose to be. (it should be noted this toy has the date of 2000)

I had the exact same pronunciation issue with Dinonychus. Similarly until relatively recently: PA-ra-SAUR-oh-LOW-fuss (Parasaurolophus) seh-LOFF-ehsis (Coelophysis)

[@colemanmoore9871]

On pronunciation - My biology teacher told us what her professor taught her: "Whoever pronounces it the loudest and most confident is correct." We are mashing Greek, Latin, German, Chinese, other languages, and proper nouns together. There is no way to "properly" pronounce these names.

[@heyitsdusk]

Dude you need to make dinosaur toys.

[@bernardfinucane2061]

The English Y has many origins. One is the Greek letter Ypsilon, which was pronounced Ü and is the precursor of the Latin V, which in turn gave birth to U and W. The Romans were too lazy to write the stem apparently. In the past the Greek Y has often been pronounced U. For example in the Mother Goose rhyme, "Polly put the kettle on/ Sukey took it off again", Sukey could also be spelled Psyche.

[@yamchadragonball6983]

Just some comments on the Jurassic Park version of these animals. Crichton based his animal on the Deinonychus, but he named them Velociraptor because it sounded "cooler", he has publicly stated this. It's not a mistake, he just decided to do it. His "velociraptors" are also incredibly powerful, what you see in the movies is toned down compared to the novel: Cheetah speed. Hyena-like bit-force, shown to be able to bite through steel wire. Chimpanzee intelligence, possibly a bit smarter. In one scene they are shown to do a vertical jump of 3 meters. They have some kind of weird decentralized nervous system (All the dino's), Muldoon uses a rocket-propelled grenade to take down a raptor since firearms aren't reliable. Chameleon-like camouflage, one raptor is stated to change its skin color to blend in. Gender-swapping. Social group animals. Pack-hunting behavior (Very advanced and rare trait). Migratory behavior, including them waiting for a boat to dock so they can board it. The JP T-rex is similarly overpowered. Henry Wu also states that he was so focused on results that he used DNA from whatever he had on hand to create the dinosaurs, he is also incapable of naming any of them. This could explain some of the strange traits of the "dinosaurs" in jurassic park, they alluded to this in Jurassic World.

Before you do the Velociraptor episode I think you could also mention Achillobator as an inspiration for the Jurassic Park raptors. It was from Mongolia, and believed to be a Velociraptor species before it was classified in 1999. It was also similar size to Deinonychus.

[@StevenBellettini]

Ezekiel O'Callaghan I only mention Jurassic Park because, for a large segment of the population, those films are the only point of contact with dinosaurs. A lot of people might not know what a _Deinonychus_ or _Achillobator_ was, but they recognize a raptor. That said: yes, we should definitely cover how the raptor misconception came about.

[@LadyhawksLairDotCom]

I have been trying my hand at dromaeosaurid restorations for quite some time now. I still almost always get something wrong. You clarified that the feathers are attached to the second finger, but I have some issues with that. How long were the feathers on that finger? It seems impractical to have long feathers on an instrument used to subdue prey. Were all three fingers free to move? If so, the feathers on them would move, too, which would be more than a bit clumsy if the feathers were long. It seems weird to put long, fragile feathers on an instrument used to kill prey. One night about fifteen years ago, my pet bird got frightened in the night and landed hard on his tail. He lost several feathers and damaged one of the follicles. His tail will never have a complete set of feathers again. And that was just from a hard landing. Think of the thrashing that would happen while a large dromaeosaur struggled to subdue prey. Long feathers on fingers would be a definite impediment. So perhaps the feathers on the hands and fingers should be small protofeathers rather than a shafted feather with barbs. Or perhaps the hands and fingers should be entirely bare. Would a dinosaur's bare hands still have scales passed down from reptilian ancestors or would the skin be more akin to the bare skin found on turkeys and vultures? Quill knobs found on the ulnae of _Velociraptor_ skeletons suggest long feathers protruded from the arm, but I'm thinking these should _not_ extend to the hands. The long fingers on _Deinonychus_ look like weapons, not structures to support long, fragile feathers. If you look at the anatomy of a bird, the longest flight feathers are on the hand and the remainder are on the ulna. The humerus does not support any flight feathers. When I look at restorations of feathered dinos on Wikipedia and elsewhere, I see the same arrangement as that of birds: long feathers on the hands and fingers. I've used that arrangement myself, but it really doesn't make sense if the larger dromaeosaurids used their long fingers and claws to subdue prey. TBH, I think only the ulna should have a few longer feathers for display, leaving the hands either bare or with smaller protofeathers that would not get in the way. Putting an entire "wing" on the hands and fingers of the larger dromaeosaurids seems contrary to their purpose. One other thing: _Microraptor_ obviously had long flight feathers on its hands and fingers. Could it bend its fingers? If so, that would probably be counterproductive to gliding. Is it possible that the second and third fingers were fused inside the integument to provide a more rigid structure for the flight feathers? I'm wondering what paleontologists have to say about this issue. Thanks.

Well, high-five for feathered paleoart! Have you read Martyniuk's blog post breaking down the Senter (2006) & Sullivan (2010) articles about forelimb function? [dinogoss 2011_05_01] What about Dr. Hone's post about Microraptor's hand feathers? [archosaurmusings 2010/03/04] (I would link you properly but KZbin doesn't let me put links in comments.) As for your feathered forearm but fuzzy and/or scaly hand proposition...it doesn't _contradict_ any evidence I've seen. Like, the 'primitive' condition for dromeosaurs' feet would've been pennaceous feathers, yet we restore them with fluff or scutes, so unless we get direct evidence proving primaries I suppose there's no reason _not_ to restore them that way. That said, if their arm feathers served some purpose other than display, suppressing the expression of pennaceous feathers on the fingers might've been more trouble than it was worth. (Admittedly, if they were used primarily to push air around we'd probably see quill knobs on the larger animals). You might be underestimating the strength & flexibility of feathers, while overestimating their length relative to the fingers, as well as the encumbrance they would represent in combat & predation. It's good that you're thinking about function & behavior when restoring dinosaur integument, though! Keep that up. As far as _Microraptor's_ fingers, I don't know enough about those critters to comment one way or the other.

Steven Bellettini No, I haven't read those papers, but I will Google the titles. I want to give you a longer answer. I didn't see your full comment because I had my KZbin "herp derp" extension enabled for use on videos where people are behaving like idiots. XD Your video doesn't fall under that category, thankfully. I'll get back to you after some study and thanks for your thoughtful reply.

As a child, all the dinosaur books I read had the dumb shambling lump stumbling around swamps idea of dinosaurs. Reading Bakker's Dinosaur Heresies was like somebody switched the light on.

[@apnosaurus]

it is interesting that we have avian scales on ornithiscians

[@brunokooij598]

5:39 I believe that rahonavis is the smallest dromaeasaurus we know of

[@paulcrowley5538]

i saw something that suggested that the big claw on the foot might have been used to climb trees, as opposed to tearing apart prey. What do we think about that?

[@nobodyimportant4778]

With every new discovery, this thing becomes more of a nightmare

[@Dirtdigger257]

This guy cracks me up love this series. Mr boden where can i find the older cnc videos ( when you had the tm1) of you and iscar rick? I checked the geek groop website and youtube and cant find them any more.

[@natedrawsthings]

So I've been curious for a while... Have you seen the new Beasts of the Mesozoic Raptor figures? They are labelled as being the most scientifically accurate dinosaur toys out there. I wonder if you've seen them and had any thoughts on them.
