Did T. rex Have Lips?

- The dinosaur lip debate is a fascinating - if slightly controversial - discussion. Did non-bird dinosaurs such as Tyrannosaurus have lips that covered their teeth, or were they exposed like a crocodile?
I am prepared to be cancelled for this.

I found this fossil and it has no skin, lips, feathers, organs or any living tissue so I conclude that it was a walking skeleton...
Pragmatism at it's finest.
It might not have had any organs, but can you be sure it didn't play the piano? One thing we do know is that pianos existed long before organs, or accordions, for that matter.
And then there's me who is just nervous about the massive, corrosive landslugs who could take down a Triceratops, that we are none the wiser of.
@@aprinnyonbreak1290 My feelings are that if we were perhaps lurking about in those days, the singular most important factor to keep in mind and to impart emphatically to our children would be that one must never, _EVER_ play leapfrog with a triceratops.
In other zoological news, a recent report has shown that a mountain of proof exists showing homosexuality occurs quite naturally across a wide spectrum of the animal kingdom, and paleontologists have now confirmed the discovery of irrefutable evidence of the existence of two new species of dinosaurs that engaged in exuberant lesbian behavior, to the point of exhaustion.
Both the likkalotopus and the dammatwahtosaur lived in a shoreline environment, and were equally at home on land and in the sea. Both were expert divers and could stay down for several minutes before coming up for air; voraciously eating tuna, the illusive red snapper, and the giant prehistoric bearded clam.
Proof that necromancy is millions of years old!

I think it's interesting to note the only animals with competely exposed teeth around today are mainly marine, spending all or the majority of their time in the water. I don't know how that factors in but it feels important why they wouldn't need to protect their teeth with lips, where land animals would have their teeth exposed to air all the time and have more need for that protection
Birds and crocodilians. The two closest relatives of dinosaurs and neither had teeth. Yes crocodiles spend a lot of time in water but they also spend a huge portion of time sunbathing on land and they lay their eggs on land and protect them for months on land. And not to mention birds spend all of their time on land and again, no lips
@@raptorsnap1738 "neither of them had teeth" um, what? Have you never seen a crocodilian? And birds don't have lips because they don't have teeth

I for one am very grateful that crocodiles, birds closest living relative, did not learn to fly. Crocodiles flying around is an absolutely terrifying thought.
They would literally be dragons XD
The good news is if they did they probably wouldn't have survived the KPg extinction since large dangerous predators didn't fare so well ;)
I think flying snakes would be more terrifying as it actually a possiblity it could happen.
Imagine a snake that had skin like flying squirrels all down it's body. So it could glide long distances as it can climb a tree and just naturally fall or do its attack lunge to give it more oof.
That is a terrifying thought, Tyler! Lol Also, great to see you here. Love your ukulele videos!
john cornwell I’m fairly certain those exist in either the Congo or Amazon. I can’t remember for certain but ye
I love the idea that they have lips. Honestly there’s just something more realistic about it to me. I never understood why their teeth looked so odd in depictions.
The never looked odd. Crocodiles have teeth just like that right now and they are visible.
@@nodo7575 Yeah. I guess I could’ve been more clear and said they looked odd to me.
@@nodo7575 yea, but crocs spend their time in water, which keeps their teeth moist, the t.rex didn't, so it would have to have lips, like other modern lizards, to keep their teeth from drying
@@brownowl4706 BUT, keep in mind that the climate back then was more humid than what it is today.
@@Dennis-zk4wv true
it actually just made me really sad when i realized we will never know for sure what a trex looked like :(
It kinda hit me like that too... I kinda imagine it to be like the monitor lizards, with the kind of hidden teeth when they open their mouth, because you uave to also think about the muscle, and other types of tissue in the mouth, and also like he said in the video, the general consensus in nature if you have teeth, is to have lips also. You could also look at the tooth and skull structure of water monitors also to see that they are extremely similar in the way the teeth look, and how the jaw looks too.
I still hope we find some good trex in a mud or something. So that we could see more 😅
It looked like a dinosaur that's for sure

I can imagine them all looking at one specific species of dino that could've been the craziest lookin thing ever and just imagine that species being sad that nobody ever found their bones so we don't know about them 😔
Yea xD
@@Nell-r0se we think not all Dino's just died we think that they evolved to birds, I think rex is chicken 🦖, they put teeth on a chicken before lol
@@annafrans6714 that's not what happened. When you hear that t rex was related to chickens, what they mean is that chickens are the closest living relatives, but by a very long shot. Early chickens (or their ancestors) already existed as a group of extremely early dinobirds by the time t rex came around. The group that the chicken's ancestors came from actually split from the ancestors of the tyrannosaurs between the jurassic and the very early cretaceous. Chickens may be the closest living relatives of t rex, but that doesn't mean they're the descendants of it. Also, the only reason birds exist at all is because smaller therapods and early birds survived the apocalypse at the end of the cretaceous, while all the large therapods bigger than a dog were killed off by the disasters, including pretty much every member of tyrannosauridae
Saying that chickens are descendants of t rex is like saying that humans are descended from lemurs. They share DNA, but they're very far off from each other on the evolution tree.
Imagine t-rexes having jowls/lips like a saint bernhard lol

Wait a second yeah-
I thought that too, what with the head fuzz and all.
I feel like so many of these problems come out of people having watched Jurassic park as a kid and wanting dinosaurs to look scarier than they might have really looked.
I think you are right. I want them to look as cool as possible...
you know that jurassic park used top paleontologists for their dinosaurs right?
Fact is, there is no proof whatsoever of what scientists theorize from a bunch of freaking bones million years old.
Even the feathers stuff is just a theory to explain how dinosaurs became birds. (which i found laughable in itself)
So true
@@JSB-2Z-2K it’s much more than to just explain how they are related to birds. Also in the film creative liberties would have been taken to make the dinosaurs more intimidating.
@@jessicawaite5140 Plus if you read the books, Jurassic Park and The Lost World, because of how Henry Wu had to make the dinos using Amphibian, Bird, and Reptile DNA. That's how Michael Criton got away with paleo inconsistencies even inside of his books. Plus ya know, chameleon on steroids aka the Carnotaurus.
So if Steven made Rexy not look like how she did when she walked the earth, that's the in universe explanation as to why that is. The same thing as for "did these have feathers, were these pack hunters, etc" basically every inconsistency in book or movie is nature vs nurture.
I feel like this is a question I could have gone my whole life without knowing. Yet, here I am, absotively posilutely needing the answer.
I think one of the reasons some people are against meat eating dinosaurs with lips is possibly because it's does not look scary or looking funny which is kinda of a silly thing to say because we have killer whales, dangerous mammals and reptiles and snakes and some dangerous fish with lips but yet still threatening and sometimes can kill.
I'm starting to genuinely hate Jurassic Park due to the crying fan boys whining about T rex having exposed teeth
Without lips, it would be drooling all the time and need more water. That make sense with crocs cuz they in the water, but evolutionary speaking, it does not make sense for a lipless trex
I can’t tell if this is a joke or not
This actually makes sense
@@taboodledoodle4263 why would it be a joke ?
@LaumiRez for elephants, tusks are utilized for defense and only appear in males, so it makes sense they’re exposed. The teeth they use to eat are still hidden beneath (you guessed it) lips.
Most animals have salivary glands, including parrots, which you'd think they wouldn't, but they do. Bird tongues are cool, they have bones in them.
I'm excited for the inevitable next phase of research, where we discuss how kissable the lips are.
@@al_monty Wouldn't you?
@@al_monty If you kissed a dinosaur on the neck, that would be getting too _"neck romancy"_ for my taste. Especially considering how long they've been dead.
Well, they sure can’t hug🤣🤣🤣🤣
exactly
Noooo 😖😫
In all the arguments I've heard against lips because the 'teeth were too big', only one word helped to end them: Baboons. For those still arguing (mostly those who have not studied anatomy), look at the direction of the labial foramina. They point towards the tooth, rather than outwards. These are for nerves and blood vessels, indicating the presence of lips. Therefore, T-Rex, etc, had lips. The matter is closed.
You can’t just look at a structure in a mammal and go “yep T.rex definitely had this too”
@@wash2361 And you are exactly the type I was talking about. *waves*
@@tardismole The debate of wether theropods had lips or not isn’t as simple as you think
@@wash2361 The depate on whether you're an expert has already ended. I suggest you stop commenting and making the results of that debate all the clearer.
@@tardismole It’s also been suggested that the foramina instead indicate the presence of neurovascular canals as seen in crocodilians

This is the kind of question that keeps me awake at night.
As a dentist student, I find the lip argument more convincing, especially with the thought of the positioning and sliding out of the socket. We get taught that the lips are a strong force on the teeth when they find their placement in school.
See, people who actually *study* anatomy will strongly lean towards lips. Most people that prefer liplessness are people who do it for the looks to make the dinosaurs look more "scary" and also people that believe Carr et al's Daspletosaurus paper, which has been disproven in an upcoming paper.

It's kind of unnerving that we will never know how these animals looked like... so frustrating
From time to time, sometimes they find skin indentations in the ground after digging up a dinosaur. But there was a case when a dinosaur has been found perfectly preserved in sand, so it wasn't just bones, I believe it was an ankylosaurus

i just wanna known if i can give them a little kiss on the lips 🥺
Just something about imaging a Trex looking at you, and opening its mouth, revealing its teeth is so much more cool than seeing the teeth before it even looks at you
Same vibe as those birds who reveal their fan-like feathers to intimidate other animals or to attract females
@Donovan Rooney
Oh what fun it is to be ganked by raptors~
I find different spins on known dinosaurs fascinating, but I agree a showcase of those massive teeth works well for the Trex while lips fit the raptor excellently
AH, the life long argument.... I'm a believer in lips. Easier to eat with and certainly better overall for survival imo. Great vid! Thanks!

It's always interesting to hear about the evolution of how Dinosaurs have been perceived over the years since Dinosaurs have been discovered.
From the 1900s to mid 20th century, right up to present day in the 21st century , debates and arguments still go on about their form and anatomy
For me, the bigger question is "How did Sauropods feed? And, did they have long prehensile tongues, like giraffes??"
I think they did.
Sauropod heads were small. But, they didn't chew -- they just cut and swallowed.
I speculate that sauropods had long tongues, which they used to strip leaves from branches and fronds,
or they used their tongues to pull vegetation into their mouths, where their incisor like teeth cut them.
However, I have never seen any description or discussion on how they ate, and whether they had long flexible tongues.
Mark Witton knows his stuff, I highly suggest people to read his post about extraoral tissue on tyrannosaurs.
As with many things in paleontology, this all isn't 100% confirmed, but it is much more likely and logical that they didn't walk around with horrendous overbites and fully exposed teeth.
Regardless, a very informative, well researched and said video as always!
I've always liked that old Charles Knight mural. He seemed to want to create an accurate reconstruction, rather than going for the dramatic like many modern paleo-artists. I think his intuition was right and T. rex had lips.
Crocodiles spend a lot of time in water, so it makes sense they don't need lips. Teeth that dry out more are generally more brittle. The mammals with exposed teeth usually have one pair of exposed fangs or tusks, not all of their teeth. IIRC, tusks continuously grow.
You think toffee has hair or feathers for his hair?

But crocs dont have lips and dont need them because they are already in moist water areas, unlike most dinosaurs that live on land

Great video!
I can't wrap my head around the fact that crocodiles are the closest living relatives to birds. They seem NOTHING alike. Evolution is fascinating.
or that brontosaurs are more closely related to birds than lizards
I have a curious question; how do you know they are relatives? Is it something in their DNA? I have gotten increasingly curious about evolution. It feels much more likely than a god (my family is religious so I have some inside-experience in that), but I'm not sure if I should trust all of what people say about evolution either. It's still just a theory. And we don't need to know how we came to be, I'd rather have humans focus on how to save our future.
@@iclynnx mostly by studying the similarities. For example chicken embryos are born with teeth tails and hands. The tail bones slowly shrink over time the hands change into wings and the tooth fuse to form a beek. There was studies on bringing back dinosaurs by manipulating a chicken ambryo and making it remain in it's original form. Chickenosauraus they call it
Here is a vid if your interested in the subject th-cam.com/video/0QVXdEOiCw8/w-d-xo.html
@Omegafox23 Oh yeah? So where did god come from, huh?
I did some research weeks ago. I searched first "is there proof of god", "does god exist", then later searched about evolution. And I found much more beliavable stuff about evolution than god. This, is coming from someone who used to hate the evolution theory, simply because my religious parents had taught me so as a kid. And I found it a bit unbeliavable that a... a fish was thought to be able to turn into a kangaroo or something (as an example). I still find it difficult to understand, but I do agree that animals can change and adapt (to their enviroment, among other stuff) over years. I just don't see why some species would change, if they were already fairly successful.
@@iclynnx this is perhaps a little unrelated but please allow me.
I always say "we don't know, so why not?". For religion it's usually a feeling, how can someone accurately explain a feeling? Sometimes people just know that the things they believe in are true, and who am I to say their world-view is wrong? Because I can't possibly know everything. This applies to science as well. There's something called a paradigm shift, which in short means that a new way of thinking, believing or seeing things has changed. Before people believed and had some evidence, that the world was flat. Philosophers to great scholars. They then invented or "came upon/found" things like a magnifying glass and the like and from there, to today, the scientific community discovers new things.
I don't think this makes "the old" any less true, because it was a reality only use fire, then to use gas, today we have discovered electricity and so on so forth. I personally think that science is as much magical-like as religion, even though I'm not a devoit. I just believe that there is so many things in the world we do not know everything about/ or cannot percieve, "so why not?" 😊
I remember reading something somewhere mentioning that part of the reason land animals have their teeth covered by something is because teeth being constantly exposed to air can dry out and damage the surface. Animals with tusks, elephants, pigs, etc., have a different sort of outer structure where this isn't a problem and crocodilians spend a lot of time in water so drying teeth isn't an issue for them. Sounds reasonable, but I don't know how truthful that is.
As for how dinosaurs are depicted, I do like the exposed teeth look, but I think a middle ground with only the tips of the biggest teeth being visible is pretty cool.
Me too.
I was thinking exactly this.
Crocs live in the water. Saber-toothed animals essentially have tusks.
Animals with fully exposed dentation tend to be aquatic only. I can't even think of a land animal with all of its teeth exposed to the air. Even the tasmanian devil has most of its mouth shut, and the ends of its canines are the only thing poking out.
You need saliva for a number of reasons. Lips keep your saliva in your mouth and keep your mouth from drying out, which keeps you hydrated as well.
I think T-rex was something like an elephant-sized, bipedal monitor lizard that had a strong bite rather than a weak one (monitor lizards have weak bites). The smaller teeth argument also makes sense to me, with teeth falling out of the socket over time. The teeth mostly just need to be able to rip.
Okay.. but, they probably did have lips considering animals on land would get damaged teeth if exposed for too long but like--is it just me who really likes the lipless version
The female t rexes had lips and bigger eyelashes. And longer hair and nails

They look better with lips as well, more bird like. Also I feel that showing T-Rex teeth might be something artists do to make them look more scary.
It is, thank Jurassic park for that mindset.
@12 Monkehs I have a feeling that the only reason there's a debate over lips is because the JP rex has exposed teeth, which is funny because literally every other dinosaur in the film (including the dilo and raptors) have their teeth fully concealed.
Because ... birds have lips?
whynottalklikeapirat technically birds do have exraoral maxillary tissue
@@prehistoricworld_ Oh alright then o.Ô still - I'd say it qualifies as pretty damn thin-lipped from a visual perspective.
a very very interesting concept. also very well put forward. its most likely that the evidence shown points towards the Tyrannosaurus had lips... especially being hunters, those protruding teeth would give off a reflection in sunlight to the sharp eyed prey they were hunting also
We could also think that the level of humidity that existed in the earth at that time could allow partially exposed teeth.
As a dental hygienist who has a side enthusiasm for paleontology, I love hearing about extra oral tissues and foramina in dinosaurs. I feel like this video is just for me 😁 Human teeth are not supposed to touch when our lips are closed and at rest, much like the examples you mentioned. It’s unhealthy and damaging for our teeth and jaws to be clamped shut when we are not actively chewing. I had to memorize where all human foramina are for when I administer local anesthetic injections. We have very few compared to the animals exhibited here, and we have super floppy lips.
Reading this with my teeth clamped right now. Why DO we clamp them?
@@MultipleIdentites Mostly stress. It’s like squeezing a stress ball or making a fist. It’s unnecessary tension. And it’ll cause your teeth to crack or chip over time and cause gum recession too.
Keep your teeth about a millimeter apart so they’re not touching, lips sealed, tongue sealed to the hard palate, breathe through your nose. That’s the ideal resting position. If you feel like you’re clenching/grinding a lot ask your dentist about a night guard (occlusal guard)
When I don't clamp my teeth, my lips just don't stay shut unless I force them. It's annoying.
@@catpoke9557 that is a common issue with malocclusion (having a bad bite). Your teeth don’t need to be wide open, half a millimeter of space will do it. If your lips can’t stay closed in a relaxed way that is actually abnormal and you should consider talking to your dental professional or a myofunctional therapist. That’s basically a physical therapist who specializes in muscles of the lips, tongue, swallowing, etc.
Crocodiles are just cosplaying as inaccurate dinosaurs
Change my mind
Deeeep
Well, considering crocodiles predate dinosaurs, the dinosaurs are actually the ones cosplaying the crocks!
Leopard seals are pinnipeds cosplaying as plesiosaurs
Change my mind
Brontosaurus cosplaying has elosaur- oh wait they are the same
Pseudosuchians are the OG archosaurs.
Time travel is the one thing I wish humans could master. Not for space travel or advancing technology even further but to go back and see the big dino boys.
Thank you for your research 😊
Now I'm just imagining a T-Rex walking around making smooching noises.
Bro tigers also have lips do they do smooching noises
No-one:
TH-cam: Did T. rex Have Lips?
internet is such a wonderful thing to have.
My theory is that they have small lips that slide up out of the way when threatened or when hunting and only cover the teeth when relaxed or to appear non threatening like searching for a mate or interacting with their young
I'd really like to see a video about the eyes of dinosaurs. I feel like in most paleoart they have very tiny eyes in those giant sockets and I always wonder why.
In applause your bravery to tackle this topic :D

Excellent explanation. I just want to share that Witton also mentioned that the facial integument of crocodilians aren't actually scales to begin with. It's highly vascularized, crackled skin.
Also there was an episode of Paleoworld from 1995-'97 where Bob Bakker noted that large foramina on the face probably indicated lips. This was 25 years ago and even he knew what was up!
That is interesting Luigi but what are scales made up of and what is "cracked keratin skin made up of" Some false dichtonomy here. And you refering to one single foramen for saurpod bakker touched up on, as he in the same video you refer to claims for this particular taxon (Tyrannosaurs) to be "lipless" by definition. Dont be as convinced as you were when you went to twitter to debunk Dr.Witmer "I can't get over Jurassic fight Club claiming that the antorbital fenestra's function was to radiate excess heat from the head like an actual engine's radiator (in reality it houses the paranasal sinuses that keep important nasal mucuses".
@@mikebrown41182 Lmao no
@@mikebrown41182 Cracked keratin skin is made of keratin.
i feel like it would just make sense for them to have lips a crocodile doesn't have lips because it's almost always in an aquatic or semi-aquatic environment so the water its in hydrates the teeth but this was not so with Tyrannosaurus it spent most of its time on dry land so lips would be needed to keep the teeth hydrated
The terrifying sound of a T-rex whistling a tune as it hunts you.
Quick Answer: It’s possible!
More accurate quick answer: Current evidence suggest lips are more likely.
Spoiler alert!
Talking abiut T rex, more likely than not, about spino, also possible but not as much likely
quicker answer: possibly.
So, this kinda seems like a “ no brainer” to me. I’m not a scientist, but every animal needs to drink water. They are comparing a terrestrial reptile to a semi aquatic reptile. I’m assuming all a croc or gator has to do to drink water is open up their throat. Now imagine the water drinking needs of a massive terrestrial reptile. It’s going to need several hundred gallons of water each day. An animal that large probably can’t lap it up like a dog or cat. They are going to have to create suction from their throat and tongue. They probably couldn’t create enough suction with exposed teeth. Lips are required for that. And now, look at vids of how every terrestrial reptile drinks water. They dip their snout in the water and suck. Can’t do that without lips.
Actually they probably just got down and used there bottom jaw as a bowl holding-the water so like they got down scooped some water up and drank it
@@murus361 Seriously. I've never heard of anyone thinking a Rex would sip water lmao
Riot now you have
Riot how else would they drink it?
Riot also it’s not sipping it’s like scooping ice cream
There’s also the related “cheek” debate; most birds have no cheeks as well as no lips, but the duck family is the exception, often having very chubby lips. So, how many dinosaurs had cheeks? Many appear so that not having them would have made keeping food in the mouth very difficult.
8:07 in the bone it's like a portrait in the center , I'm sure it looks like that lol
Therapist: Lipped T-rex can't hurt you, he doesn't exist

It's not that bad
The arguments for and against were presented beautifully
Me: Trying to sleep.
My brain at 2:33 AM: Dude I wonder if T-rex had lips.
Woke up at 2am last night wondering this, luckily this video is just what I needed.
Excellent, up to date and comprehensive summary of the "lip or no lip" controversy in non avian dinosaurs, and particularly the T-Rex and other iconic theropods. One thing that should have been mentioned though in favor of lips, might have been the preserved evidence of true, scale covered, lizard-type lips in mummies of other types of dinosaurs, most notably the recently discovered Nodosaur mummy from Alberta. Given that the geologic conditions of "northern" North America have preserved the skin of several dinosaurs, and that this same region was also home of T-Rex and Albertosaurus, perhaps one of their mummies preserved with full skin impression (including the lips) will be discovered and then the controversy will finally end!
To be honest, I think its more likely that Tyrannosaurs, Charcharodontosaurs, and Spinosaurs had more croc-like mouths.
@@CoreyStudios2000 I think it's incredibly unlikely that they had lips, and I would bet a lot of money on it.
Crocodiles live in the water and have a substantially different hunting style. Now we also know that the closest relatives of T-rex that actually have skin impressions had lips. Aquatic animals can get by without lips because they live in the water, so their mouths don't dry out.
Land animals that can't seal their mouth shut will get dehydrated. Hippos cover their massive tusks with massive lips.
And, platypus is a mammal without lips... because it has a beak.
Beaks are a different case because they seal.
The lack of a saliva discussion around lips is actually mind-boggling to me. Lips exist because you need to use saliva to break down food, and saliva is mostly water, which evaporates.
Earth’s past has always and will always be fascinating, honestly the lips look right, but the T. rex with no lips looks cooler.
Actually if he had lips and we prefer without lips one
The without lips one looks like Eren titan form from attack on Titan lol
@@forestbertrand I prefer a humble and wise lipped T Rex, I would spend time in coffee shop with him discussing the meaning of life👍🏻
ah but what about a t-rex baring its teeth like a wolf
Lipsless T-rexes are the orc variation.
I personaly prefer with lips I don't know to explain but it looks more natural and less Hollywood production
1950: In the future we’ll have flying cars.
2021: Did the T-Rex have lips?
This was in the news not long ago. The answer is yes, they did have lips because the teeth that they have examined don’t have wear and tear as say crocodile teeth do when exposed.
I’ve always believed they had lips and got annoyed when their teeth were out
😂😂
I’m pretty sure we all dint know dinosaurs had lips when we were children, thanks to Jurassic park and Dino documentaries in the past that dinosaurs there dint had lips(carnivores).
Bromar O same
So what about their noses? I always wonder about the amount of face structure lost, and how different mammal skulls look bare vs fleshed out. What would we think a horse looked like if there were no extant lineages to infer traits from?
Short answer: Horrifying. Utterly, damn, grossly, horrifying.
Long answer: It'd probably be very off and bony. With a short nose.
While there are still many soft tissue structures lost (mainly in the form of crests and dewlaps), birds, lizards, crocodilians, etc. all have quite a bit less soft tissue than mammals covering their skulls, making restoring them a bit more straightforward. And since dinosaurs have more in common with them than with mammals, one can restore them accordingly.
The thing is, mammals are very fleshy in the face, birds and crocodilians are not.

This incredible animal used to actually exist!

Very sober and convincing presentation ! - - - many in favor of the lipless version might be so because of the more 'cool' look with the impressive toothrow fully exposed - but actually the closed lips gives a much more liflike and convincing natural look !!!
