Real Archosaurs Boom by Osmatar Real Archosaurs Boom by Osmatar
This one obscure movie from a franchise about giant mutant frogs got a new trailer, you may have heard about it. After youtube forced me to view it several times I felt like I had to do this.

Also, in case you are curious, the evidence we have from extant archosaurs suggests that open-mouthed roaring/screaming was not a things dinosaurs did, but rather did something similar to crocodilians and ratites. You can make your GMO frog monsters do whatever you like, though. Except survive pyroclastic flows, unlike male protagonists.

(The background was pretty much traced from a screencap of the trailer, the Tyrannosaurus is based on Scott Hartman's Sue skeletal and Crash McCreery's original T-rex color scheme and Owen Grady is based on Chris Pratt.)


Edit: I changed the title from "Real Archosaurs Don't Roar" because it was misleading people from the point which is closed-mouth vocalization, not making loud noises.

How many reptiles do you know of that roar like a bear or lion?
None.

Actually, the roaring isn't nearly as bad as the fact that, in the JP movies, the T. Rex will just roar for no reason. Like, in the original it was trying to eat people (which I honestly doubt a Tyrannosaurus would be interested in doing anyways) and it just stops, looks up at the sky, and screams at it. Why? What did the sky do to it? Was she trying to scare the sky? Maybe she thought the sky was trying to eat her food?

In light of these discoveries one can look with a fresh eye at sound that emus and ostriches make. Although, I must admit that T-rex that hums at you instead of roaring is quite anticathartic.

Hehe At first I thought it would be a joke in which the dinosaurs would "croak" for having frog gene, but referring to your description, everything combines. 
And speaking of dino-frogs, have you thought that Yoshi from Super Mario Bros would also be a JP dinosaur, because of his long tongue, his lack of feathers and his bulging eyes? That´s crazy.

Screw the haters. This is a great picture. I didn't think I would like seeing a t. rex with a vocal sac, but looking at this picture proved me wrong. In fact, I wouldn't be surprised if the real t. rex actually had a vocal sac.

The animal in this picture is supposed to be a a genetically modified version of a close so a few feathers are not that bad even if the original T. rex was completely scaly.

I have a theory, I think that T. Rex may have had a roar. Think about it, birds don't have a roar but neither did rodents back in dinosaur times. The only reason animals like lions or gorillas have roars is because now mammals are the dominant species. Maybe back in the day, T. Rex or other dinosaurs may have had roars like a deeper lion roar or something...If I'm wrong, please tell me. Still, awesome drawing man! I can't wait for the new movie!

OBJECTION!

it is likely that tyrannosaurids, being social creatures had a variety of vocalizations, some open-mouthed, some close-mouthed.
Like it is very likely it could hiss!
because both birds and croc do that, and they do it open-mouthed!

watch-www.youtube.com/watch?v=7gRQUd…
-www.youtube.com/watch?v=I28Qne…

second point, while it is true for it to have this, you lot have to remeber that the dinosaur-tree is very diverse and likely developed many ways of communication, whose to say that roars wouldn't be one of them. Like in territory for example, or in a fight?

to say that it could ONLY do closed-mouth calls is limiting, especially when considering how diverse dinosaurs are.

Mammals are really the only animals that roar, so giving dinosaurs roar is a chauvinistic stereotype. At best, maybe they rumbled or boomed like alligators or crocodiles. Also, many birds produce ungodly-sounding screams when they want to sound scary, maybe that is what some dinosaurs did, but deeper. In my mind, roaring is the bourgeois, boring option that makes the least amount of sense.

maybe, but listen to the sound of a casowary, even if it is not techically "roaring", it sounds so similar that you may as well call it that.

besides, the reason why i'm ok with roaring dinosaur is that they are a group serpate from both mammals and reptiles, and we don't know 100% what their vocal cords were like.

besides, just because mammals are the only ones CURRENTLY that can roar, that doesn't mean that creatures in the distant past couldn't.

and honest, I think the t-rex roar is comparable to some bird calls, just a lot deep and throaty.
I 'm not saying that is what the "real" t-rex sounded like, but you have to have an open mind with these things and we need to understand what the broad definition of a "roar" is.

You're missing the point.

Think for a second. Maybe we can't say that no dinosaur ever made a noise that resembled a roar, but why exactly is it so important to be obsessed with the idea that T-rex could roar?

I know exactly why. Because a dinosaur roaring is a romantic stereotype that a lot of people are attached to, and its hard for people to separate these feelings from reality and our misguided expectations of reality. We live in a world where roars are made by large, mammalian apex predators, thus we want to associate our romantic image of extinct apex predators with this image. I reiterate, roaring is only really done by mammals, and to superimpose this sort of thing on extinct animals is inaccurate and stupid, because we are only doing it based on our bias about what we think sounds cool and scary.

We don't know precisely what dinosaur vocal apparatus were like, but phylogenetic bracketing tells us that something like a primitive bird or alligator is the most likely. So giving dinosaurs sounds that are just modified copy-paste of lions, elephants or other mammals makes no sense.

Dinosaurs are NOT separate from birds, at all, even though they are very separate from reptiles and mammals. And really, no bird makes a roaring sound. I have heard cassowaries up close multiple times, it is not at all like a roar. It is really a deep, throaty bass thrumming noise, which is frankly more similar to the supposed booming noise that is hypothesized for T-rex.

Dinosaurs may have made loud noises, but it is ambiguous leaning towards unlikely that the large predators sounded like lions or bulls or elephants. A bird that screams or screeches is frankly a better blueprint for what a loud, intimidating carnosaur would sound like, just make it deeper.

1-indeed

2- not really, again these are genetically engineered dinosaurs, so I there is nothing wrong there.

3- not really, could that be said about dinosaurs like sauropods, triceratops, hadrosaurs, ankylosaurus etc?
and another thing the JP animals (while they do roar) mostly don't sound like "generic" mammals.

4- that is true, but by that logic, you're saying that a human or a chimp should give the same should as a mouse, a whale or an elephant.
in fact, by that logic, you might as well say the a cat should sound like a monkey, because they are both mammals aren't they?

and birds can hiss!

4.1- even if that was the case, most people would call that "booming" a roar
so would they a hiss etc.

5-you're missing my point, listen to the sound that JP animals make, like the Brachiosaurus, the raptors, the hadrosaurs and the t-rex etc
the reference the makers used were birds and reptile, with just a tiny bit of mammal for throatness

listen to the raptors particularly, they don;t like mammals at all!

Okay, firstly why are you bringing JP dinosaurs into this? A GMO animal could sound like a slide-whistle or a fart or anything you wanted. I was trying to focus on why you were trying to argue that the real T-rex roared. And I maintain that I know why, because it's a romantic stereotype that is ingrained in the media, it is not based at all on fact or reality.

A large meat eater will roar loudly, a large herbivore will make a bull bellow or a noise like a whale, a small carnivore will scream and hiss. They may not sound exactly like certain animals, but those are the stereotypes 100%, I just laid them out for you in plain english, and most of them have no basis in science. Also, the JP T-rex is a mix of lion, elephant and upset horse, if you speed up or pitch-up the sound samples its really obvious.

No, no. You don't understand how phylogenetic bracketing works at all. As a rule, the better constrained it is to close relatives, the more accurate it is. You were using examples of vastly distantly related animals to try and make me sound ridiculous. For T-rex, the best we have are ostriches, cassowaries and alligators, the only way we are going to have a better constraint on this bracket is if we find a living relative of Dilong or Alioramus, or find a fossil of its vocal chords.

I was going to mention hissing, it sounds scary and both birds and crocs do it, still tangential to what we are talking about: roaring.

I don't think so. When I first heard a cassowary, I had no idea what they sounded like, I did not think it sounded like a roar. It sounded like a bass note thrumming. If you cast your definition wide enough, you might as well call every loud sound a roar, which is stupid. I roar slightly after I drink a can of coke, but we call that a belch.

Strange and sad that you actually believe that. T-rex in JP was horses, elephants and lions. The typical raptor scream is a dolphin and a walrus. Not sure what the Parasaurolophus was, or the Brach, but the Brach sounds a lot like a whale at any rate, which is yet another trite stereotype. If anything a brontosaur type dinosaur, with such a long oesophagus, could have sounded like a swan or a crane, just very loud and deep. The spitter used a lot of bird honks and things, a lot of the incidental other raptor noises were geese and penguins and things, but the main noises were not bird for the most part.

1- fair enough, but until farther evidence comes to light, let's argee to disargee.

2-I do understand phylogenetic bracketing, but the thing to understand is that I used cats and humans because that is how distantly relative a t-rex is to an emu.
and because we're using birds and croc (which bare in mind live very different lifestyles to a t-rex) they are not always a good "direct" reference.

so yes, I'm trying to keep open-minded (until we find vocal cords of Alioramus)

3- exactly, and think of it this way, if deep enough, and done mainly from the throat a "hiss" would sound like a roar

4- no, having a wide definition is a good thing, plus there is, of course, convergent evolution!

5- perhaps, but the combined sound is not really like mammals, but more like a bird.
they even had paleontologists (of the time) check them.

I find it debatable that a loud deep hiss would sound like a roar, its an exhalation with no voice at all, that's essentially what a hiss is. Not like a roar at all. The larger kinds of snakes will sound sometimes like a scream or a whistle when they hiss.

Dinosaurs might have made a sound like a roar, but for now, we can only use primitive flightless birds and crocodilians.

No, if you have such a wide definition that anything sufficiently deep and loud is a roar, then all definitions go out the window.

The fact that you think ANY of the JP dinosaurs sound "more like a bird" in their movie appearances is subjective I think. As a child, I thought the raptor hiss frankly sounded like a horror movie creature, the Brachs sounded like whales, the T-rex sounded vaguely mechanical. I think they were trying to make them sound like animals that also are supposed to give you a certain reaction, like a character. If they had the Paleontologist check them to sound like birds, I would legitimately like to see a source for that claim.

1 - From "The Land Before Time"  this Tyrannosaurus had a raspy hissing/screeching sort of roar instead of the bellowing roar of JP rex and those that came afterwards and also used it more naturally (instead of doing it when hunting or after killing something for no reason) rest of the time it was just breathing and rumbling, it was antagonist of the original first movie which sort of made me who I am with its darker but also naturally heartfelt tone, thank you Don Bluth...

Freedom of speech means that existing opinions can be made fun of of condemned, if there is cause to think that they should.

Frankly, in a world where the default public opinion is "dinosaurs look stupid with feathers, science has ruined dinosaurs", I would rather stick with the people that nitpick Jurassic World and say that it's stupid.

I still watched and enjoyed Jurassic World, I just didn't for a moment put it on a pedestal or defend it being a legitimate portrayal of dinosaurs. The series is currently moneymaking and fanservice, I really enjoyed Jurassic world because of how much aint-it-cool fanservice there was, but that doesnt mean I much liked the way the dinosaurs looked.

Look at it this way, I enjoy Exobiology and drawing speculative sci-fi drawings of alien creatures. Does that mean that I don't enjoy Star Wars, no, I still enjoy Star Wars, despite the fact it has many very silly and overly anthropomorphic or trite alien designs. I will join other fans in making fun of how stupid some of these are, just as much as I make fun of Jurassic World's dinosaurs.

Being in 2 minds about something is fine in my opinion. I personally think defending Jurassic World is stupid, because THEY are the ones putting the proper names on plainly inaccurate dinosaurs, and tainting the public's perception of dinosaurs. Simultaneously they are making asstons of money from essentially misrepresenting and damaging science. I have talked to science educators that have had to explain to children that Indominus rex is NOT A REAL DINOSAUR. The people who make fun of Jurassic World are the underdogs here, they are absolutely correct in their opinion, science should be making more money from dinosaurs, not hollywood hacks.

But all of this doesn't mean you can't watch a film to just enjoy yourself. Defending a multi-billion dollar industry in the face of ridicule from a small bunch of people on the internet is pointless.

I understand all of the excuses and in-universe context for the consistency of JP/JW dinos, I have used them myself, I just think that there's nothing wrong with pointing out how inaccurate this is. The real reason for hating these portrayals is that the popcorn-eating typical layperson moviegoer doesn't know any better, and will gladly accept that these are realistic. Media has a responsibility, or it should, to not misrepresent things and perpetuate untruths, that's what I think.

*sigh* Can't people just accept that the Jurassic Park/Jurassic World movies are built upon the fact they AREN'T scientifically accurate? Honestly, that's beauty of them all. It's not cluttered up by the new findings and evidence we have that says otherwise. PLus, they have subtly CONFIRMED that they aren't intended to be scientifically accurate. Ex. Dr. Henry Wu's conversation with Simon Masrani:

"Nothing in Jurassic World is natural. We always have always spliced/used the genomes of other animals, and if their genetic code were pure, some of them would look much different. But you didn't ask for reality, you asked for more teeth."

There you have it. And the dinosaurs would probably sound different like you said if their genetic code were pure. But it's not. The genome was incomplete, and they had to use substitutes, which is why they look and sound the way they do in the JP movies. Now I'm not hating or anything, you raise good points, but the franchise is built upon the inaccuracies, because the inaccuracies have an element of truth to them also.

And as for Chris Pratt surviving a pyroclastic flow, there is also the suspense of disbelief. Just throwing that out there :)

"continuity standards"? So completely changing the raptor design from the original films is okay as long as there are no feathers even though they had feathers in the third film? You can't use both "genetic engineering" and "continuity" to excuse JW's lazy creature design. They kind of cancel each other out. Pick one.
