Why Dinosaurs Would Have Ruled the Earth Featuring Dr. Steve Brusatte 

New! Is 'Oumuamua a Light Sail? W/Dr. Avi Loeb:​ ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-VlpVIyBCG3s.html You can find Dr. Steve Brusatte's book, The Rise and Fall of The Dinosaurs here: amzn.to/2CmjWbf

That moment when you realize that the universe is being simulated by intelligent dinosaurs who wanted to see how the planet would have evolved if their close encounter with an asteroid 65 million years ago had impacted instead. No wonder everyone loves dinosaurs. We've been subtly programmed to love the idea of our creators.

Channels like Event Horizon are important for peoples education ! I'm in my mid fifties and learning new stuff all the time from these channels ! Entertaining too !

Man, what an interview! Most of the questions I still had about dinosaurs were brought up _and_ answered!

It still blows my mind...this planet had Dinasours! And giant marsupials! I makes one wonder with awe, that somewhere out there in the vastness of space...there is a planet out there full of giant Dinasours and Marsupials! It's my happy place! (And slightly terrifying place) This planets history is outrageously incredible! We have the greatest story! I mean Massive creatures so different from us that existed for hundreds of millions of years! Imagine other planets out there and their story! Whenever I camp in a rainforest or the bush, the incredible multiple bird sounds from morning to night always makes me think of what the world would have been like pre modern human. It sounds like a Jurassic park!

I still hunt Theropods every Wednesday. Lee’s has a great $5 three piece special that’s hard to beat.

Along with being a sci fi nerd I've always also been a Dinosaur nerd, if you will...obsessed with this video well done! Fantastic interview, I really enjoyed Steven he is so refreshingly not only intelligent and accomplished but DOWN TO EARTH at the same time, wich is rare at times. I truly appreciated his opening and his inspirations behind his new book. I'm going to try to purchase it! Again, wonderful content here.

What a great teacher this man must be. He knows how to paint a mental picture. I love thinking about dinosaurs and these massive changes in ecology and species. And Brusatte's enthusiasm is very apparent and so delightful.

I just ordered the book. I'm retired now and have the time to pursue my interest! I've always been fascinated with paleontology. Btw I don't think that we will find any evidence of past life on mars, but that's just my opinion.

I really appreciated Brusatte's explanation of the dividing line between the Jurassic and Cretaceous eras. His analogy with the natural versus arbitrary boundaries between countries on a map brought this division into focus for me. Thank you, Event Horizon and Dr. Steve Brusatte.

John is the best interviewer I have ever heard. I want a John interview.

Thank you JMG. So many times creators will not listen to their fans when they say they want longer videos and you did. Not just that you did it with amazing guests on very interesting topics. This made my day!

Fantastic episode. Also great job at editing with contextual visuals. 👍

500 new dinosaurs in the last decade, that's amazing

This is quickly becomming my favourite RU-vid channel. It also made me check out and purchase one of your books. Truly fascinating John.

I love Dr. Steve Brusatte's passion and energy!

What an awesome interview!! Just discovered the channel and have been working through some of the older content. A brilliant conversation and very eye opening. Already have the book downloaded on my kindle (:

Awesome guest! So enthusiastic about what he does... it's always inspiring to hear people who are still excited about there field many years into their career... and that little outro with the AI was fun... looking forward to Isaac next week!

Amazing how fast an hour can go by! Great show as usual! I'll definitely be looking forward to Isaac Arthur next week!

Great stuff..realy like ur videos and the reson is mostly the images u put up and they r synhronized with the topic u are discusing.u can realy see the quality of effort u guys putt in.thumbs up 👍

Very nice interview! I'm definitely liking this longer format, and that opening music...can you open all your videos with it, it's appropriately epic for this channel!

I really like how you ask a question and then let him just talk freely. Awesome talk.

How did I missed this episode. What a great production!!, i love how your use music to create an atmosphere when describing the great extinction events. Top notch!!

I'm always down for anything with Dr. Steve Brusatte. I could listen to him talk about dinosaurs forever! What a great episode!

Really great vid, as always🤙 I really enjoy the depth of detail that you go to and still keep things perfectly understandable. Keep up the amazing work!

Currently reading Dr. Brusatte's book. It's very informative, and very entertaining - I had no idea the life of a palaeontologist was so odd!

Ah science and reason time. My favorite day of the week. Keep up the excellent work John.

Yet another great show. Thanks for the upload

Liking this preemptively, going to watch when I get home from work. Excited :)

This was a nice change of pace for the channel. Love your space talks but all science is pretty great. I love thinking about evolution and prehistoric times.

Was a pleasant experience listening to this, thank you both

I got a laugh at how Anna wanted to jump ship to I.A.'s channel. Clever way to give a compliment. :)

Great interview. By coincidence I was looking at Steve's book in the mall today. I'm going to go back tomorrow and get it. Keep the new shows coming John!

I love the added visuals in this episode

Said it before and I'll say it again another great interview you're legend 👍👌👏

This program is great. This channel should blow up. Love the introduction and the A.I. voice

Such a great episode!! Thank you thank you!!

OMG next guest is going to be awesome. Great episode as always.

Just imagine a mouse sized fossil being found on mars. The science of Biology would explode.

More dinosaur content please. Need to get my mind off all this alien stuff until the dust settles.

The reason I enjoy listening and watching this channel is the enjoyment you can hear in your voice and the people explaining these speculations

I'm back-pedaling through your videos, having only recently discovered your program. I always love hearing new info on the dinosaurs, and paleontology in general. I'm surprised that Steve didn't mention that a powerful driver of evolution after the Permian extinction was low oxygen levels, (less than 15 percent). This led to the development of super-efficient lungs that had a "flow through" design, which birds still possess. In fact, it was their lungs that enabled flight. Think about Canada geese that fly over the Rockies at 30,000 feet elevation. Just sayin'....

Love the new channel ! Ty great vid and very interesting!

Thanks again for another very professional and informative show.

My favourite one so far, what a fantastic guest. Keep up the good work!

really enjoyed this JMG. thanks.

Very interesting stuff. Good interview questions. I just added Dr Steve's book to my to-read list. Always a treat to listen to someone who's so passionate about science.

Hey John, really enjoying the new channel. I like the variety so far. Keep it up.

You're the man dude. Keep up the good stuff. Looking forward to part 2 with Isaac Arthur.

If only the dinos would've had a space program...... Tyrannosaurus SpaceX 😂

Steve Brusatte sounds like the “Sean Carroll” of dinosaurs. Enjoyable presentation.

I just found this channel, though I do watch your other channel. It's nice to see you take on this sort of video. I find evolution fascinating, especially dinosaurs--and the eventual rise of mammals. Thank you for uploading!

Great interview! Thankyou. We need more content like this on RU-vid, Dinosaurs are super interesting.

As always, great presentation by John Michael john Godier. Missed this episode when it was first release. It's like thinking the Pepperidge Farm Chessmen Cookies bag was empty. Then finding one last "missing cookie" at the bottom of the bag! :P

My understanding was that dinosaurs actually started losing diversity towards the end of the Cretaceous period and that the asteroid was more like the final mercy for non-avian dinosaurs, rather than wiping all of them out during the course of a few years. My information might be old or incorrect, but to my knowledge the youngest fossils they found so far are about 66 million years ago, while the asteroid impact happened 65 million years ago, with almost a million year gap where dinosaurs are already gone. It would be really interesting to talk about these gaps and the best timelines that we can establish.

This was really enjoyable. Great interview and guest!

Thanks! What a great format for a RU-vid video. It's an illustrated podcast!

When I was a kid, I would watch any and every documentary about dinosaurs I could find. I think I'll go check Steve's book out.

Awesome video John loving the new channel

Honestly can't stop watching. Love all your episodes.

Watching this after work as I fall asleep. Nothing beats it.

*Event Horizon title panel slowly scrolls out from behind a tree* That's the good stuff

Excellent video!

I love these topics! Thank you!!

Beautiful and brilliant. Love your show and teaching.. Ever since I I was a kid I loved dinosaurs. Thanks 👍

so Dr. Steve Brusatte is really still a child who is fascinated with Dinosaurs and who took it to the ultimate conclusion. I'm jealous!!

This is going to go down as one of the best episodes of this show. This was amazing! Great guest!

Unbelievably great episode, they always are, but still, just great.

One of my favorite channels. Well written and well narrated.

Thank you John for another very interesting EH segment and Dr. Steve B. for your narrative. There are some early depictions of early civilized humans co-habitating with a small number of up-right walking dinosaurs. Did they actually go extinct? Or did they adapt and survive much longer? That we have forgotten about from our past? ps...I met Dr. Charles Cockell at HMP-2000 on Devon Island where I was gathering data for design of a new MARS Space suit!

dinosaurs were tough physically. But in a 120 plus million years they couldn't evolve into intelligent beings. Shows comparatively humans are doing amazing.

I. Really appreciate the documentary style use of imagery used in this episode- well done

A very intresting presentation. Great viewing.

From what I've read Dinosaurs didn't really dominate until the end Triassic but rather their close relatives the Crocodylomorphs another group of Archosaurs which were way more diverse and active that really is a boundary that is underestimated I'm really curious why some groups survived where as others perished. Unlike the Permian extinction and Creteceous extinction we don't really have the full story for the Triassic mass extinction. Though over all the Triassic was a harsh time for life with many starts and stops for life as later waves of the Great Dying repeatedly struck so maybe it was simply a continuation brought by the prolonged suffering of Pangea? Supercontinents seem to be quite disastrous for life as we know it Pangea's predecessor Rodinia according to research looks to be a major player in the Neoprotozoic snowball Earth Events. The speaker here does underestimate mammals though as while they never got huge they were far more diverse than most people realize and they too were similarly devastated at the end of the cretaceous. Overall they probably occupied most of the Nocturnal Niches Given the impact seems to have been primarily driven by the complete collapse of the biosphere under several years of global darkness it is likely the high activity levels became a double edged sword that wiped out all the active animals on the planet that didn't find a alternative nonperishable food source akin to seeds. As for the extinctions they were far more complex than this guest implies Both the Permian and the Cretaceous extinctions seem to have had a long term stressor namely the super continent Pangea with limited nutrient availability due to low erosion, and the Deccan Traps respectively, straining the ecosystem followed by a sudden destructive blow. This was probably important in the extinction, both The Siberian Traps of the end Permian extinction and the Cretaceous Asteroid erupted/impacted into extremely rich Hydrocarbon Deposits, The thick Coal Deposits of the Carboniferous rain-forests set-ablaze as the earth fractured and spewed molten magma and the Sulfur Rich Petroleum of the shallow seas near what is now the Gulf of Mexico/Caribbean. The sudden and rapid release of hydrocarbons from both events seem to have been instrumental in forging the disasters themselves via the rapid injection of CO2. Though The end Cretaceous deathblow for the dinosaurs based on samples from the impact site and looking at the extinctions of both Flora and Fauna seems to be primarily driven by the immediate loss of sunlight as the Ejecta provided for several years of Darkness. Plants and algae were particularly hard hit which likely led to active Herbivores starving to death and active Carnivores following in their wake. As such perhaps if the Asteroid had struck elsewhere on the planet and not blocked out the sun completely the nonavian dinos would have been able to carry on their empire. After all even today Birds are so much more metabolically efficient than mammals in particular the respiratory system of Crocs and Birds is way better than what mammals have getting more air for less energy. Birds at least feature a higher neural density compared to mammals ourselves included i.e. are able to do more per unit volume smarter per unit volume. And mammals on average have higher body temperatures which could be a double edged sword in a hothouse climatic phase such as the one present over the Mesozoic and early Cenozoic Earth. Mammals are not slouches but probably had adapted to rule the night where there was no reason to grow huge instead radiating into diverse niches across the planet. Large size after all is far more of a challenge for mammals at least on land than it was for the Dinosaurs. There are biological limits imposed by several adaptations such as large endothermic animals suffering the risk of overheating, adapting blood processing into the internal skeleton which limits the structural role bones can support, inefficient respiratory system etc. Today Only Cetaceans have really been able to overcome these limits due to water buoyancy solving the weight problem and water's thermal properties making overheating less of a problem. And then there is the whole story of plants and insects and the rise in pollination originally in Cycads and possibly Gynosperms? Before the super competitor Angiosperms were able to rapidly rise and replace them with their truncated Genomes that is.... Those poor Cycads and Ginkoes didn't really stand a chance... It may look less impressive to us but it was still a big deal! Also Ferns while they may look "ancient" they actually rapidly diversified and radiated through the late Mesozoic!

This episode hit me right in the cloaca.

A particularly *excellent episode* I watched TWICE!

For what it's worth, I'll comment on this one. I work in Human Cardio/Pulmonary, I discouraged my Son from Human Medicine. What he did was Veterinary then Avian Science. We discuss this frequently to this day. Granted he's not here to represent himself, but I can confidently say we both transpose Birds and Dinosaurs as one in the same. I tend to see through a Birds Feathers and see the General Morphology represented there.

36:00 Yes!!! That was great XD

Just subbed. Science is awesome.

finally...dinosaurs..bout time you guys got to it!!!! lol good job JMG and Ross...enjoyed a lot..thanks guys!!

Rise And Fall is bloody ace, such a good book, especially the audio version, dinotastic! 👍

48:36 If ever someone needed a soundbite of a mad scientist laughing, this is it. You're welcome.

OMG what an intro!

I read Brusattes book on Dinosaurs, I highly recommend it. The last chapters focus on the last moments of life, how so many of these creatures met their tragic end. Very powerful and sad. Definitely worth buying.

And another excellent interview.

I'm 38 and I will ask for this book for Christmas ! Thanks a lot😁

How many collect calls to Issac can you make before next episode? lol

More Dino content please!!! Absolutely loved this talk.

Thank you for your vids!

BEST. CHANNEL. ON. RU-vid. 🏆

Epic intro again!

Steve is a great speaker really entertained listening to him

Thanks for doing what you do sir. I love both your channels.

i've been subscribed for a while now, have clicked the bell and it said i'd get all notifications, but have yet to receive one.

Great video John! Very interesting I always wonder if there are alien worlds out there with dinosaur type creatures on it. I love Event Horizon best science channel on RU-vid! Thanks John.

This guy is a great talker! Really enjoyed it.

Steve is a very engaging speaker - anyone with an interest the history of dinosaurs will enjoy this one!

Could we get Ken Ham on one day for an episode with some side splitting laughs ;D

Astropaleontology….I cant wait for that day as well!

Dr. Peter Ward (book-"Out of thin air")offers a reason for dinosaur success: They had a different breathing system--bird breathing. They didn't breathe in, then out. They breathed in and out together. Their environment began as a low oxygen environment. Mammals larger than mouse-sized couldn't get enough oxygen to compete with dinosaurs. Dinosaurs could. By the time oxygen levels rose from 12% back to 21% dinosaurs were too dominant.
