Piecing together the behaviour of long extinct groups is naturally very difficult, but can be done with care. New fossil from the Gobi deserts of Mongolia are helping us work out how these animals lived and died together.
David Hone is a palaeontologist and writer. His research focuses on the behaviour and ecology of the dinosaurs and their flying relatives, the pterosaurs. He writes about palaeontology and science outreach online through his own blog and on the Guardian.

Paleontology was my first passion. As young as 6 years old I needed my parents to buy every dinosaur book I came across. I hogged the computer for hours just researching facts on long extinct creatures. I had damn near encyclopedic knowledge of the subject by the time I was 9.
Then I got to middle school, and fitting in and making friends and conforming to their standard of “cool” became the most important thing in my life. I lost my passion.
Now I’m a senior in college, about to finish my finance degree, and I find myself circling back to this stuff which intrigued me so long ago.
I love this man. He’s like a mirror into what life could have been like if I had pursued something I truly loved over trying to fit in, be “successful” and make money.
My peers all think I should get a job in finance, like my degree says, but I’m looking for ways to get back to the root of who I truly am deep down. I may never be a paleontologist, but I don’t want to settle for the 9-5, high paying soul crusher of the corporate world. I am not built for that life.
I hear you, I was also an absolute expert aged nine!
I relate to a lot of what you just said
Hunter I think you should combine the two things you’ve spent your life studying. Why not spend a few years in finance, make connections, acquire funds assets etc and move towards paleontologic philanthropy perhaps? Learn how finances work in that area and maybe you can do both. Finance manager for a badass museum or maybe help to acquire funds for new digs or something? I am by no means an expert in anything, just one passionate human being to another I think you should do exactly what makes you excited. Your friends don’t know you like you do, they know who they want to perceive you as… do the thing that you don’t want to stop doing, it will make going to work so much easier.
This is even better than what I suggested.
Get a grip!
Many animals turn their backs to high wind and general lashing rain. You see horses doing it today. Maybe that's why they were all found facing the same direction when they died?
That's an interesting observation, the Gobi is well known for severe sand storms and paleontologist have determined that this condition existed during the Cretaceous Period related to this particular formation. They also believe that many of these animals were killed by these storms and they very well have kept their back to the wind to breathe and then were overwhelmed and suffocated. A paleontologist friend of mine working over there was caught in several of these storms and he said you had to face away from the winds sand blasting effect and you had to cover your mouth with a cloth just to breathe. Your probably correct in your view point. Also these wind storms travel from out of the west and move south east forming a massive wind front across the Gobi.
Yes
He did state it could have been wind from a sandstorm. More importantly, he states they were together for "whatever reason" and then killed over. This man is a lot more careful in how he presents his claims or facts. So, while yes, what you mentioned could have been the case for what we see, Dave definitely gave it a thought as a possibility for it.
David Hone is ace. He is everything a lecturer needs to be, keen, knowledgeable and funny. He is infectious.
more dinosaur lectures, please!! 😊😊😊
This guy is good.
Enjoyed every minute and I could easily have watched for an other hour or two.
Zeedijk Mike he has a few other great lectures. You could easily get your two hours in :)
+Anchor Bait : Thanks - Searched on his name and found a few more hours of enjoyment.
Zeedijk Mike he has one on dinosaur behavior that's pretty fascinating. Cheers
I'm on my second.
Wonderful lecture! What would be proof of social behaviour in dinosaurs? I tend to think of social behavoiur as a spectrum, with, say, bird colonies at one end and wolf packs at the other. It seems most herbivourous dinosaurs would be at the lower end of that spectrum. But there has been evidence of group hunting among carnivourous dinosaurs. Is this complex pack behaviour, or could there be other explanations?
Lovely talk! I've read his book "The Tyranosaur Chronicles" and it was amazing! He is very good at what he does and is truly inspiring!
It makes me start to count the days until I can finally go to the Museu da Lourinhã (just 2 weeks to go), where I'm a volunteer and a fossil preparator.
How did the expedition go? I'm writing this 10 months after your comment.
PortugueseEagle, how did it go? I'm so happy for you, that you had a wonderful chance like that plus I'm just a little bit jealous. Lol
How does one become a fossil preparator ?
Excellent lecturer! Interesting lecture delivered in such a lively manner. Would like to see more of this guy and his knowledge of dinosaurs.
Susan Harris he now has made a great podcast called “terrible lizards”, look it up :)
David Hone is wonderful! This was a great lecture. More dinosaur and early man lectures, please!
we need more lectures this guy makes the topic 100 times mpre interesting
Always awesome, and thankyou very much for uploading these lectures and giving us all the ability to enjoy them.
This lecture does raise the issue of investigating the differences between sociality and aggregation. Animals aggregate for practical reasons related to survival, but that involves communication and group dynamics, even on a very rudimentary scale. It would be interesting to examine the social dynamics amongst a wide range of species, and see the variations in behaviour. That kind of generalised approach might provide some insight into the dynamics of extinct species too.
29:10 I WANT TO SEE WHAT HES SHOWING SO BAD!! please dont make us miss interesting slides
git gud
Wow, I can't believe I've just watched 3 dinosaur lectures in a row with great interest... and normally I've the attention span on parity with that of a goldfish.
Recommended right under the lecture which Hone ends with "I could go on about the social behavior of tyrannosauruses for days" :D Spot on.
A breath of fresh air. He just relates the science and leaves the children’s stories to the guys in the funny hats🤠
Got damit, I love tho hear this guy talk. More david hone everywhere pls.
I feel like this man could successfully host a show called Last Era Tonight
enjoyed this talk by David Hone so much, thank you.
This guy is awesome! Fascinating content, engaging delivery...I'm hooked!
I've spent the last couple days watching various videos on the Tyrannosaurus Rex, and this one was the best by far! Great presentation and very up-to-date information that other videos lacked!
I just love listening to your wise words David. I got mad love for you guys and girls. Nobody knows you dont get rich doing this sort of work. I do. Thank you for all you do.
Couldn't play the video, but that glassesusa commercial sure played each time I tried. These un-skip-able commercials at the beginnings of videos mess up the play.
There shouldn't be any unskippable ads in front of our videos. Let us look into what's going on there.
Just came across this great channel. Seems much like the British Ted talks
much better than ted
you mean TED is the International RI
only going waaaaay back to in time to Michael Faraday who started it of in 1800s
TED is a bit of a curate's egg. If you throw away the good bits of the curate's egg.
excellent presentation. Thank you for sharing.
Excellent presentation
Great lecture
Really enjoyed this one!
brilliant lecture !
31:00 - The nearest living relative of the lion is the leopard, not the tiger, but the point remains the same.
They're all members of panthera.
Great talk!
Thanks from the land of Sue here in Chicago, USA Dr. Hone. Looking forward to hearing more of your lectures. Is it likely the juveniles form flocking behavior as a safety mechanism?
That was bloody fascinating.
He has no equal in paleontology.. A fantastic presentation, as usual. Great discussion.
Paleontology isnt just dinosaurs.
@@Arbitrageur_ I know that well. It involves several disciplines, geology being another huge facet of it.
Phil Manning comes to mind. Hone is still in the shadows of Bakker, Paul, Currie, list goes on an on.
I love that desk!!
OMG this guy is so good!
Yes, but especially because the others are execrables. It's hard to find any serious academic field with more low quality academics than paleontology. He is an exception.
What do you call a group of dinosaurs? A school...herd ... flock ... a pride of tyrannosaurs ... a murder of Pterodactyls ... a crash of triceratops ... what? We need a new/old names for these designations ...
I can't believe the opening slide didn't say something like "Dinosaur Party in Mongolia!!"
I wonder, given how common T-Rex was, why no eggs have ever been found?
Was T-Rex unique, could it have had live offspring?
I know that his highly improbable, BUT?
Dinosaur eggs have only been found in a limited range of deposits namely sandy deserts, flood plains and sandy beaches. T-rex would not have laid eggs in any of those places and so it is very unlikely that any will ever be found.
great video
This was really fascingsting and made alot of really grest points!
I just noticed the demographic in the lecture, mainly over 50's, this is a shame and this subject needs more 'young blood' to take up the torch of this very broad and diverse subject for future generations.
Many under 50 are READING about the same info online or in books.
Or the lecture was scheduled during regular work hours.
are there any updates to this subject by this speaker? anyone know?
He mentioned how we have some sex-determining methods in dinosaurs. What are some examples of these? I know of the work with medullary bone done on T. rex, but are there other methods known?
Nearly everything predates on nestling, fawns, baby rabbits, and young carnivore. Hyenas will predate young lions, a cow will eat ground nesting bird nests (and it's contents). The young aren't as a rule, as fast or agile as an adult or adolescent animal. A puma seems to prefer younger animals (not as large and powerful as the adults).
0:54 that huge ornithischian is called "Shantungsaurus"
Given how the sand of those mongolian finds is not quite sand stone and barely stuck together sand, are the finds themselves actual bones, or the 'usual' minerals replacing the actual bone that is long gone?
They are minerilized and most are very fragile and have to be stabilized by a solution like paleobond recently or commercial Butvar a number of years ago. Back when the AMNH collected in they 1920s they used shellac to keep the minerized bone from crumbling apart. The matrix is like compacted sand but can be easily removed with dental tools and scribes. Some specimens are found there in harder compacted sand stone.
When the rest of the world is giving me the business, I just focus on dinosaurs.
'But it doesn't mean that we're just guessing, which a lot of people kind of assume'
- Sore spot!! :-D
Social dinosaurs. That title could be interpreted in a lot of different ways.
Awesome
I like this.
MORE D I N O LECTURES P L E A S E
Bayardo Canizalez look up his podcast “terrible lizards”
Listening to that thing about inferring behavior rather than observing it made me think: why do people believe science about things like whether dinosaurs had feathers but not about how viruses work or climate change existing?
Gracey People have a tendency to believe what makes them feel comfortable. We can believe some crazy things then doubt other things that have heaps of solid evidence. We are a contrary species.
Answer: illogic.
@@fleetskipper1810 Bit of a late reply. From my obervations, it's politics. Those two last topics you mentioned, have been politicized, and it changes how people percieve them.

I don't want this guy to stop talking about Dinosaurs.
You can only learn so much from the fossil record. We're about 70 million years too late
7:20 Bita mails and fimails
The juveniles are all together cause they're in school, ya nut!
A thing I wonder about is that if birds are the descendants of dinosaurs, were there no actual birds around at the same time as them?
Enantiornithes (birds) which were fairly common in the Cretaceous period lived alongside (non avian) dinosaurs.
Thank you. for the info. I was forgetting about the fossilized bird with the claws on its wings Archaeopteryx? i think.
# letsbuydaveashirt Love him but been wearing the same shirt for at least 7 years. 🤣😊
They're moving in herds. They do move in herds.
It's funny to think a pigeon is a dinosaur
All modern birds are dinosaurs
@@M3l0dy__. I know and there awesome
That's my problem, I am missing frills on my horns.
But it's very important to understand birds are only dinosaurs in the sense that they are dinosaurs in a single group. Just looking at the first major division of dinosaurs between the "reptile hip" dinosaurs and the "bird hip" dinosaurs, all birds belong in the reptile hip subfamily.
It makes no sense at all to tell your audience "birds are dinosaurs" when there are almost no other theropods that had full feather coverage in adults and birds are almost the only theropods without any scales.
It's a blanket statement like saying that humans are monkeys.
Yes, there is significant diversity between dinosaurs and birds; however some dinosaurs are more closely related to birds than to other dinosaurs. This just means that birds are the descendants of *some* dinosaurs, and other dinosaurs were significantly different. In this case, T-Rex is one of the closely related cousins to birds.
Two words: Yutyrannus huali
@@jasonvoorhees5180 great references, I couldn't hold back a response but your is perfect. Just wondering if your related to Michael Voorhees the famed Nebraska paleontologist? Collected there many years.
David Letasi Nope just decided to have my username as Jason Voorhes cause it sounded cool at the time.
@@TlalocTemporal No it could as well mean birds resemble the dinosaur template and tricked humans.
'Look after your egg'.
'Because your egg will look after you'.
Nah Dave, it's just 'Look after your egg'.
Ligs = ribs + limbs
he was obviously thinking of two words at the same time... choosing between two statements.... ribs and legs or ribs and limbs. "ligs" was a mental misfire in choosing one of the two words but accidentally combining them into one weird word. He did it a couple of times in this video, I've done it a lot myself.
Did social dinosaurs use social media?
americans wouldn't say 10 to 15cm, no we would say a foot to a foot and a half. a meter is easier for us, because it is so close to a yard, and we know what a yard is, just not a kilometer. we know what a mile is though. we failed on the hubble space telescope, because the scientists measure in metric, while all perkin elmer's, (who was a major machinery manufacturer), equipment was all standard.
Paublus Americanus yeah but ALL scientific measurements are done in metric, even in America.
+MonsterBaby Steve Wilson _"... ALL scientific measurements are done in metric, ..."_
Not at all. Physicists in particular use all sorts of non-SI units, such as measuring mass in MeV/c^2, or whatever units it is in which _c_ = 1. Astronomers still use cgs units, which are distinct from SI units (look at the electrical units, for example), not to mention parsecs and light years and the like. Scientists use whatever units are appropriate, without any dogmatic preference for any particular system.
@@michaelsommers2356 -- Perhaps it would be better to say: "(Nearly) All scientific measurements are done in an SI compatible system." The point here being everyone uses a system based on powers of ten, and not whatever tiers seemed good at the time.

Are you sure they're not sheep eggs...???
Wow!
^..^~~
Nice talk,but there are still a huge margin for us to understand the social behaviour of any species of dinosaurs.
All we can find in fossils are the physical appearance,diet and habitat of that creature that died for million of years.
Remember behaviour is a kind of of spiritual aspect that can't be seen by rocks.All we can do is to find evidence and compare their behaviour with our modern organism.
"Spiritual aspect" means that behaviours are from your heart,even though you may find dinosaur footprints,"bullet" marks,egg shells etc...
They are still only a fraction of the entire species's behaviour,therefore you can't conclude the whole as if you've got only a tiny bit of clues.You cant be sure on what you've got.😀 Have fun - The future paleo-boy.
Offtrailed Dino The speaker does a good job of explaining that. And uses a fancy word for trace evidence that's not bone, rather than "spiritual". Let's not put "spirit" and "science" too close together lest an unnatural reaction occur and contaminate the noosphere.
"Behavior is *spiritual* and from the heart"? This has to be one of the most ludicrous statements I have ever seen on the internet.
Behavior is a biological response to an organism's environment, it's not fucking mystical. I could argue that you're conflating behavior with emotion, but even emotion isn't *spiritual* , it's more based in cognitive thought than instinctual responses, but it can still be physiologically quantified, good grief. Also, you're argument that we can never truly discover and understand the behavior of extinct animals because that can't be seen in rocks (we *do* have far more material than just bones in rocks, by the way) suggests that you're yet another person who will only except conclusions based on direct evidence and who has apparently never heard of phylogenetic bracketing in your life. This isn't just speculation we're talking about, it's inference. You are clearly in no position to be talking about anything related to science, or reality itself for that matter.
Lions feed in groups with the "lion"s share" going to Mr. Lion. No such thing as a "tiger's share" for good reason.
Which is funny because, usually, it’s Mrs Lion who brings dinner home!

No, the term "coprolite" is used for conservatives. Well, the older ones.

Welcome to science.
It's sad to hear a scientist trotting out the tired old "alpha male" myth 🤦♀️
“There are some ideas so absurd that only an intellectual could believe them.”
― George Orwell
Lol everyone in the audience is so damn old.
It's simple. You have to figure out if the dinosaurs are like tigers or lions. Which is smarter? Lions because they are social. Tigers are lone hunters for the most part. Their social skills are limited.
Of course this is all speculation.
Spinosaurs were definitely not social dinosaurs. Even during their juvenile years they led a solitary existence.
There’s exactly 0 evidence for what you’re saying
@@jasonvoorhees5180 Jurassic Park 3😂
Not really to my taste; just a bit too feverish in the presentation with many declarations and espoused "certainties", bordering arrogance. More often than not, it's better to tone down the excitement during educational lectures, so that the facts speak for themselves and the presenter doesn't lose credibility via sensationalism/emotionalism.
Aldus huxley would call this 'pesudo knowledge'
Social behaviour in the human beings sounds very strange. In? You mean between? Or among? The? Which the?
When scientists take a weird start, like this, how "in" earth can we expect something good?! Why do very very very very smart people write such nonsense without even SEEING this is weird? They lost contact with normal blokes?!
Adults still believing in dinosaurs......
Fools like you still believing dinosaurs weren't real animals.
Non avian Dinosaurs did exist
What a load of tosh we no nothing of there habits, you can not tell this from bones
No it's YOU that knows nothing of their habits because YOU aren't a paleontologist. You have literally no experience in this field whatsoever and you think you understand what's possible to tell from fossils better than the people who built their careers on studying said fossils? The fact that you refer to what they examine as bones proves you haven't got a clue what you're even talking about. Fossils are not bones you dunce. How do you not know that? Lol apparently my five year old daughter knows more than you about fossils.
It is so incredible to me, that you can even think possible, that you know what happened thousands of years ago, let alone millions of years ago. This is the epitome of arrogance and narcissism. Oh, not to mention ignorance. Wow, just wow!
Sure, let's go back to assuming everything in the world is powered by unknowable spirits.
