TEDxVancouver - Jack Horner - The Shape-Shifting Skulls of Dinosaurs

[Velox415]

Wow. Jack Horner looks so old. :s I remember watching him as a kid. How old is he; he's only like 60 or 65 I thought?

[TheLivirus]

I find it really hard to belive that sawing the bones apart is the least destructive way to determine if they're spoungy or not. What about Xrays? What about comparing their densities?

[Sykora727]

Does anyone else think this guy sounds like the Joker?

[Sykora727]

@Sykora727 Y so serious, Dinosaur? Lemme saw your bones!

[fknugly222]

This man kills Dinosaurs! I SHALL NAME HIM DINOBANE!

[givenupsasuke]

I appreciate what this guy does and what he brings to the table, but am I the only one who thinks he talks about little kids WAY too much?

He's like a closet pedophile.

[louis424]

@givenupsasuke the fact that he mentions them twice in 20 minutes? yes, you are the only one.

[Tareltonlives]

Bullshit. 

[llj355]

@Tareltonlives Oh really? Care to provide evidence like Mr. Horner rather than just spewing objections?

[CamelJaq]

@llj355 I'd like to introduce you to the fighting montana dinosaurs. It is of two older individuals dieing after a conflict. Notice the skull that could never be that of a Trex and rugous texture on the bones of the Nano. Means Nano was its own species.

[LeonardoYokhana]

@Tareltonlives its true when you have a set of 15 or 16 dinos theres a chance that there may be like only 5-8 real dinos cause like jack said people just love to name dinosaurs so its 1 of the many reasons there are more than hundreads of species of dinosaurs people just look at skulls of 2 dinosaurs and if theres a slight diffrence they sometimes think of it as a new spieces

ALLOMETRIC CRANIAL ONTOGENY

[Pssybart]

Jack Horner has become some kind of a Dino Myth Buster. He has also long argued that T-Rex was a pure scavenger. So far, T-Rex has withstood the test and remains an active predator to most scientists but we should appreciate that Horner actually goes out to test these animals. It forces us to re-examine our evidence and it many times corrects overlooked errors.

[Tareltonlives]

@Pssybart Or rather, Dino MythMAKER since most of his theories make no biological sense.

[CamelJaq]

@Pssybart Now if only he could do it right for a change.

[piecheese1214]

Scientists: They like to name things.

[joeceph]

@piecheese1214 Just like Mr. Horner himself, for example "Achelousaurus horneri" and "Anasazisaurus horneri".

[studioandreasvideo]

Am i the only one who thinks this man sounds like the Joker from the latest Batman Movie.

Just close your eyes and imagine, the Joker telling the story. It has the calm way of speaking, the pauses and the sound of the licking of the lips :P

[CelestisFang]

this is none sense Samson and MOR 008 are bigger than MOR 555.....

and Samson and MOR 008 are tyrannosaurus X, not tyrannosaurus "rex"

[congtron]

CHICKEN DINOSAUR! - CHICKEN DINOSAUR!

[Mutubeish]

this is fun! =)

[Mutubeish]

@Mutubeish

yea and interesting!

[sonofpikaia]

Why is velocyraptor not a jong T-rex?

[ChowMeinChowdown]

@sonofpikaia I hope this is a joke.

[sonofpikaia]

@ChowMeinChowdown No it's not a joke.

I do not mean to say that I think a velocyreptor is a jong T-rex, I just wane know explicit what the arguments are?

I never studied dinos so i don't know, I'm just interested in the answer?

[ChowMeinChowdown]

@sonofpikaia My apologies for misunderstanding your question. Well, the T-Rex is different from the velociraptor on so many different levels. I'm sure just a simple Wiki on both of them is going to reveal quite a bit.

But I'd like to give your question a shot - First, they are different on morphological grounds (proportions, anatomy, size, osteometrics, etc). Second, behavorial (probably scavenger vs hunter) and biomechanical differences. Third, genetics. In fact, do check out their cladograms.

[MarkArandjus]

Wait... so Dinosaurs grew like Pokemon?

BTW why physically cut them up, why not use some type of scanner or an x-ray?

[ChowMeinChowdown]

@MarkArandjus In the beginnings of light microscope development, sections from plants and animals were manually prepared using razor blades. It was found that to observe the structure of the specimen under observation it was important to make clean reproducible cuts on the order of 100 µm, through which light can be transmitted. This allowed for the observation of samples using light microscopes in a transmission mode.

I think main reason is because most labs aren't using digital microscopes.

[S0XF0X]

SAY WHAT?! Best video ever!

[hechoenjap]

He reminds me of Chevy Chase

[DraskyVanderhoff]

This guy should be the Grandpa that everyone should have. Love this guy!

[closestcontinuer]

Good talk, but why are these people laughing?

[1davidlister1]

@closestcontinuer

because they get the jokes

[ABAHDpdx]

@1davidlister1 Ha! yeah they get the jokes. Brilliant!

[LockeShocke]

Did anybody else think that this was not funny at any of the places that people laughed?

[Elyphaleth]

Great! Now I must to forget a lot of dinosaur's names!

[ImAnotherZang]

wonder if Horner even knows about CT scans.....

[SpelKille]

@ImAnotherZang I doubt that would work with fossilized bones.

[ImAnotherZang]

@SpelKille it does. it simply makesa 3D picture of the item along with the insides without actually cutting it open. It worked with alot of other fossils too.

[Tareltonlives]

He had to make sure none of his dignity and credibility survived.

[YojimboAuron]

@Tareltonlives

wha?

[LoveMyDogs]

Very interesting! Definitely worth watching ... really enjoyed this. :)
