Dr Stephen Brusatte - Tyrannosaur Discoveries 

I have binged all of the professors videos and I do not regret 1 second of that time.

I am reading your book The Rise and fall of the Dinosaurs, it is an excellent book. Great lecture on Tyrannosaurs Rex

I really like Dr. Brusatte's speaking style! It's a nice mix of understatement and animation -- shows just enough excitement about his subject-matter to keep the audience engaged, interested and invested but, at the same time, doesn't over-sell it (although it is hard to over-sell a subject as fascinating as dinosaurs)

One of greatest science communicators of our era.

Another scientist who's infectious enthusiasm makes you hang on every word. Really enjoyed this.

Wonderful lecture. This series is excellent. Thank you, University of Edinburgh.

Very nice. It was a long time since I saw a summary about paleontology and dinosaurs up to date.

I literally just finished reading this guys book 5minutes Ago and looked him up. Looking forward to watching this now! The book is great!

Spectacular job. I'd love more lectures by him m

Dr. Brusatte's book 'Dinosaur Palaeobiology' is an absolute read for any palaeobiologist. Enjoyed reading that!

Very interesting talk. Thanks for sharing.

Absolutely Fabulous....

So awesome, thank you :)

TY Edinburgh for letting me get my Smarty Pants on. Supper good and now Im subscribed. Make me proud

palaentology is very interesting about the dinosaurs on how they lived.

Amaizing sir

27:40 When was there a fightscene between a T-rex and a Triceratops in Jurassic Park?

Stephen is a looker!

Does anybody other than John Horner study the juveniles rather than naming them as a new species ?

1200 is just a scratch as they think all we have is 10% at best of what lived then. Imagine the ones we dont know about. Scary thoughts that rattle the structure of my skull.

turn the volume WAAAAAAY UP.

I was afraid he would speak with a scottish accent, but then he smacked his lips...

Enjoyed this, thank you!

I wonder if it was colder in Mongolia and that's why the dinos there had feathers

I'm curious, what is the speaker's rational when he states that T-Rex was the biggest predator that has ever lived on land? Spinosaurus is thought to be the largest carnivorous dinosaur, but likely spent most of it's life in the water, so maybe it didn't "live on land'. But then there is also Giganotosaurus which is thought to be bigger as well.

That was a great, informative lecture; I really enjoyed it! It is pathetic, as evidenced by some comments here, that elementary school dinosaur lovers grow up to think they know the subject better than a leading world researcher. Thanks again Dr. Brusatte!

Could I volunteer to help dig up fossil?

chickens are t-rex's and ducks are spinosaurs...

I don't know why but when ever there's talk about the Bolide event that eliminated the Dino's and their kin there's often never a mention given to the Deccan Traps Flood Basalt event in India dated to the exact time, which surely would have impacted the worlds climate and ecology, after all it's larger flood basalt in Siberia that's blame (or the massive trigger to) for the End Permian extinction.

Love T. rex !

i've always loved dinosaurs since i was 6 and i'm 10 now

I really like rise and the fall of the dinosaurs.

Could it be possible that those smaller tyranosaurs, which lived alongside bigger tyranosaurs, might be, not different species, but all of the same species, being just of different ages?

“Herbivorous dinosaurs grew bigger than anything alive today”-🤔...blue whale? “T-Rex was the largest carnivore to ever walk the earth”-🤔...Spinosaurus?

It’s sill hard for me to imagine a feathered T-Rex!

The black and white diagram of the early Siberian T-Rex looks a lot like Alaskan images of gods!

At 28:20 he said "feathered dinosaurs were only first found in 1997. Less than 20 years ago. Until then we had NEVER found a dinosaur with feathers and now we have". That is simply wrong. Archeopteryx and it's feathers were discovered the 1860s.

Very good and interesting lecture and I have a lot of respect for Brusatte and his work. However, he mentions a fight between Tyrannosaurus Rex and Triceratops in Jurassic Park but the only scene with Triceratops in that movie was a sick one lying on the ground and the only other dinosaur Tyrannosaurus faught against in that movie was Velociraptor towards the end.

I feel like I'm asking a very simple question, but I'm confused by some of the phylogenic terminology. Tyrannosaur TyrannosauRIDae TyrannosauROIDae Tyrannosaurus

Itsa lika the Ferrari of the Cretaceous si,..no 😲⁉

Great lecture, it's amazing what happens in three years. Now, scientists believe big T-Rex's probably weighed upwards of 9-12 tonnes. 5 is somewhat scrawny; hence, juvenile by today's estimates.

Charcharodontosaurids and Spinosaurids: Are we a joke to you?

what would one name a native scottish dinosaur?

His “tutting” is driving me crazy. He punctuates every comma and every period with a “tsk”.

I think this is before Spinosaurus was discovered was described as the largest!

Video starts at 16 min.

I think they are far more scary with feathers!

Spinosaurus 8 tonnes was bigger than T Rex and not really an aquatic dinosaur

biggest predator to live on land? Forget Giganotosaurus? Spinosaurus? Mapusaurus? Carcharodontosaurus?

>Krasnoyarsk >A Very Small Region HAHAHAHAHAHAHAHAHAHAHAHA

He mawkishly admits that large herbivores were dying off, but doesn't mention the mass extinction of foraminifera that predates the impact, nor the Deccan Traps, nor the land-bridge (which might explain how tyrannosaurs got to North America in the first place), but is quite certain that an asteroid, or comet, impact caused a global extinction on land and in the seas across the globe, which had coincidentally already begun long before the impact occurred. His fascinating expertise is obviously in the rise of tyrannosaurs, but not in their disappearance. Interesting to note: the difference in age between the earliest tyrannosaurs and tyrannosaurus rex is longer than that of late Cretaceous theropods and their closest living relatives: chickens.

LOL all these little keyboard professors in the comments trying to call him out based on their corny ass Jurassic Park educations. I think the guy who has named at least 15 new species probably knows more than you guys do about the entire scope of the dinosaur kingdom, especially theropods. Why don't you noobs just go fanboy about Megalodon on some cryptozoology video?

How awkward is the intro!

It is a strange thought that not only was there a dinosaur weighing next to nothing, but it still exists. I refer to the Bee Hummingbird, which weighs about the same as a £1 coin! A far cry from the 100 ton sauropods. Palaeontologists tend to jump onto bandwagons: the feathered dinosaur band waggon, the brightly patterened colourful dinosaur band waggon, the polar dinosaur able to survive four months of total darkness band waggon, and others. There is some truth in all these bandwaggons, but some palaeontologists tend to extrapolate them too far. Colourful dinosaurs were probably limited to very small ones, just as they are today. Large animals like rhinos, elephants, hippos, bison, moose, buffalo, seladang,crocs etc tend to be dull and subdued in colour.

'He was a rich, white guy'...really fed up of people highlighting skin colour in just about everything.

we also know NOW Trex did not have feathers

„Human sized“ is pretty meaningless and not helpful when discussing animals so different from humans.

White hatred in dinosaur lecture?

That intro... Stephen... Did you make them say all that... I've never heard such a ridiculously long credit listing... You forgot to mention your momma thinks you're special, too... Just start the damn lecture and let that speak for itself. Damn!

4 minutes 30 seconds in and he already says something wrong

His lip smacking is awful.

glad i didnt pay to hear this guy speak

All that pageantry, and then the speaker's microphone turns into a potato. What a half-assed lecture.

Wow, isnt it just so amazing that this so called tyrannosaur genius never brought up the really important issue of soft tissue and blood cells that were found in the bones of a t rex ! also notice on the q&a how quickly he skipped past the feather q. also on the q&a all his actions really stood out as being a total liar ! He must have said evolution said evolution about 40 times trying reinforce everything he said ! MUPPET ! WHAT IS SCATLAND ????

Please stop smacking your lips, it's gross when magnified by my headphones.

Lol what evolution?

Birds ☄️. Misinformation again

so why did he say a rich white guy? woke five years ago 100 million years is a long time for a speices to evolve into a totally different animal so calling a dinosaur a tyranosaur from 170 million years ago is bad science. i only made it to 20 min.

Why does a guy from the early 20th century's political and racial views even matter? 🙄 Save your PC BS and let's learn about dinosaurs. That's why we're here!
