History of the Earth Part 3: Phanerozoic Eon - Mesozoic Era
Вставка
- Опубліковано 21 кві 2022
- We are working our way through the Phanerozoic eon, and we got through the Paleozoic era. Next up, the Mesozoic era! In this era we see the rise and fall of the dinosaurs, those beloved beasts. How did this come to pass? What can we say about Earth's topography during this time? Let's take a look!

I’m really glad that you described in full detail the effects of the asteroid impact at the end of the Cretaceous, instead of vaguely stating “most life and all non-avian dinosaurs died, but now there are mammals”. Great video!
Two mass extinctions in one video! Professor Dave knows how to pack a punch! Very enjoyable. Your content keeps getting better and better. Thanks for you and your team's hard work.
The way humanity is such a tiny blip in the life of earth always gets me
This may be my favorite series you have done
Love the series. Please consider breaking it all down to smaller bits of time and explaining more.
Nice content! I did not even notice this video came out just recently. History is so incredibly fascinating.
These are so interesting Dave. I wish they were more in depth because I find myself enjoying them so much. Excellent work.
Love all your videos sir but these are my favorites, please keep this series going. Thank you sir.
Thank you so much about this series, it's awesome
Excellent series.
That.....sniff.....was beautiful. Thanks, Dave.
I love this series. Happy Earth Day 🌎
Been waiting for part 3 😌🙏
Prof dave, what makes you choose these topics? You seem to know a lot and I mean a lot of fields and have been producing content for years. I am grateful for your dedication and passion.
I'm just going down the line of all the major academic subjects! Geology is a big one that I had been wanting to do for a while. But I didn't write these scripts. I don't write most of my content any longer, unless it's chemistry-related.
@@ProfessorDaveExplains or smacking pseudoscientists
he doesnt know alot, he thinks he know alot, that's the difference.
It's called vulgarisation.
Listen to real prof in one domain, you'll see dave talk about shit 99% of the time
@@bilibangbang Says the rude mid-wit pseudo intellectual...
@@bilibangbang umm didn’t he literally say that? Lmao
I love that Professor Dave is the default of UA-cam when I don't change to another video. Arigato Sensei, I'm a little smarter today than I was yesterday. Most respectful bow to Sensei.
you're missing a "u" there chief
I'm really enjoying this series! Thanks for all you do. ❤❤
Those CGI dinos always remind me of growing up in the 90s when everyone was obsessed with Jurassic Park. Good stuff Prof. Dave!
That movie still holds up! Love it!
my favorite series at the moment, i am always delighted when i get the notification that a new video is released
Amazing that asteroid impact destroyed 80 percent of life and yet isn’t nearly the biggest extinction event in earths history
@Hexum Blazkowicz It wouldn't be much more diverse. If anything, the dinosaurs were a brake on evolution with how successfull they were towards the end. If it wasn't for the big reset button, mammals and grasses would never have ruled the modern era.
@Hexum Blazkowicz Mammals did coexist. But, modern mammals? That's a different story. They won't be able to. Mammals achieved their current diversity only because dinosaurs went extinct. Otherwise, we would still CO-EXIST with dinosaurs, but you will walk on four legs and will be eating a grasshopper for dinner at the moment.
Although, you can get more information about your idea by watching 'Flintstones.'
Isn’t it true that many small dinosaurs survived this mass extinction? And they are the ancestors of today’s birds? I’m probably misunderstanding something.
No that's true, technically not all dinosaurs died out and birds are dinosaurs
I suppose "nearly all" may have been more accurate.
The birds had already started their evolution in the Jurassic period and, by the time the asteroid hit at the end of the Cretaceous, had already more than 90 million years of evolution unter their belt. At that point they were already pretty close to today's birds in morphology. So, while belonging to the dinosaurs, birds had already fully branched off and come to their own when the main dinosaur lineages where wiped out. In light of that, stating that all dinosaurs got wiped out isn't entirely wrong. Though the better wording would be that all non-avian dinosaurs went extinct.
BTW, despite the name and similar reptilian origin, Pterosaurs and Ichtiosaurs were not actually dinosaurs but entirely different lineages. And I think it's the same with Plesiosaurs.
@@ProfessorDaveExplains is there a dead start with a plant 5x larger then earth causing a reset on earth every 13,000 years?
@@Vibe4ant no. I'm not Dave, but I can tell you that this isn't true. Not sure where you heard this conspiracy theory, but there's no plant (or planet) that resets anything every 13K years. There's historical and archeological sites that old that would have been affected, and don't show any of that.
I love this series
While the chart showing the various eons, eras, periods, and epochs is very informative and accurate, it does distort the relative time frames. I’d love it if you also point out that while the 63 million years of the cenozoic takes up the most space on the chart, it is actually quite small compared to the other periods.
Welcome to flat Mars!
Brief but effective.
👍👍
Man, you're awesome!
keep up the great work!
where is part 4?
coming next week!
@@ProfessorDaveExplains Aweesome!
Well explained.
"Trouble was brewing in Siberia" - A euphemism used in Russia where the diet is heavy on beer, caribou, and onions.
(Massive escapes of noxious gasses associated with the eruption of a mantle plume - I know that feeling)
Not really, I made it up. But it should be.
this stuff is so cool tbh
Cheers Prof! I enjoy paleontology and follow PBS Eons but this broad view is really helpful
youre saving my life for my exam rn thank u
As always an excellent presentation.
Trouble brewing in Siberia- extremely understated 😂
hello professor Dave. Can you make a video on how to solve alcohol and phenol exercises ?
Informative ❤️
A video id like to see you do: breakdown the perpetual energy-free energy videos. You know the ac generator running a electric motor running the generator.
Thanks 🙏
First and i can't wait to watch when i get home :)
Is Yellowstone on a similar path of a mantel plume buildup and eventual explosion?
The collapsing T Rex is so epic 🔥
Dave: All dinosaurs died.
Birds: Am I a joke to you?
The Mesozoic is amazing, and always fascinated me.
Amazing fairy tale...
LOL. Just commenting this before the evangelicals do
@@neilbeaton9498 Fairy Tail is a funny well written anime series
amazing indeed!
Could a meteor strike have been what set of the Siberian traps (that then elected enough material to completely obliterate any signs of that impact)?
As Tunguska, and Chelibinsk, are proofs that the area is prone to larger meteor strikes.
Just curious 🤔🙂
That's actually a theory out there. So not far out of reality ngl. I mean, hell, something similar happened during the KPG. Some scientists think it's what set off the Deccan Traps, another Flood Basalt Eruption.
man i could of really used that last era video, final tomorrow ):
I wish you would have gone into more depth about how the some dinosaurs survived and eventually became birds.
These are the type of videos that I wish were like 8 hours long, hah. I never get tired of learning about this stuff!
AronRa has some pretty lengthy videos, if you’re not already familiar.
"Let's move forward and wrap up... with [the Cenozoic Era]..."
To where? I can't find Part 4. Please give a link?
Coming soon!
Just came in after watching part 2, and by the no doubt dumbest coincidence I'm reading a book where the term 'orogeny' occurs a lot.
I mean, it's a post-apocalyptic sci-fi/fantasy trilogy, but whatever.
All inosaurs gone? What about bird's?
Only 4 the of 13 videos are available 9 are hidden. How can we watch the rest?
And just found the release date for this video!
Will be released about one per week!
Wonderful, professor I wonder are you going to continue the mycology series?
I'm studying mycology and I really liked the series a lot!
I've got some coming for you soon!
@@ProfessorDaveExplains Thanks professor 😊
the mushrooms be growing and they aren't plants
there you go, no series needed ;)
@@keegan6388 xd
Bro You should Explain the Periods in more details
Looking forward to the Professor Dave philosophy series!
One of my grandparents survived these extinctions
Could you explain how the non-avian dinosaurs survived?
Love this series, really do, but, seriously, we're getting mass in "titanic" units now?
1:30 until today! omnicide for convenience!
How long did the asteroid's effects last?
15 years
a Question i have: is it true that Chickens and blackbirds evolved from T-Rexes?
Amphibians and reptiles are still with us from the Devonian period does this mean they survived the great dying era ?
Obviously the K-Pg event didn't kill off all plants that utilized photosynthisis. If it had it's likely that we would have none today.
Where is part 4?
To be released shortly.
why use miles :(
Our love of dinosaurs started on Jurassic Park, aren't we Professor Dave?
No I loved them when I was a little kid.
@@ProfessorDaveExplains Speaking of dinosaurs, do you think the Loch Ness Monster is actually an Elasmosaurus that survived the extinction of dinosaurs? You also said in the video that marine animals were safe from the blast wave coming from the asteroid upon impact
@@flatearthisahoax4030 Late, but I'm pretty sure the Loch Ness Monster is actually a whale dick. Correct me if I'm wrong, though.
"Trouble was brewing in Siberia" Yeah, best get used to that happening, Siberia...
I've been listening to a progressive metal band called The Ocean. They made 2 brilliant albums about the Phanerozoic Eon.
"50 Million Titanics" - Americans will do everything to avoid proper metric units. It's okay, I'll go look up the mass of a Titanic myself.
Edit: I find it surprisingly hard to find the actual mass of the Titanic.
Professor Dave, how come you failed to mention the DeclanTraps and that monumental eruption’s impact on the dinosaur environment before the meteor strike? There has not been a mass extinction that did not involve volcanism. At 66 MYA is no different. I
❤
Again I gotta correct u but I won't make it long like the last video. Not all dinosaurs died from the meteor, birds r theropod dinosaurs n the only group of them to survive cuz they were smaller than most dinosaurs but also able to fly long distances I search of food n somehow they also had an edge on the smaller pterosaurs tha remained by the end of the cretaceous period allowing the birds to outcompete them into extinction
I love how creationists avoid early development of earth and the early era's/periods/eons of earth especially the animals like the plague lol. Bcuz it goes against all their claims and they can't back them up.
What specifically is being avoided by these creationists? I don't really know what the detail of their beliefs/young earth theories.
No ambiguity in the name, "THE GREAT DYING." Can't help but to add some bass when I say that name.
Kent Hovind: "You see Dave, in the bible..." XD
Professor Dave, have you provided any content on the subject matter of climate change?
Not yet, I'm planning extensive content on ecology and environmental science so it will be covered in extreme detail.
@@ProfessorDaveExplains Cheers Professor!
it’s so scary to think how a great dying could absolutely happen because of human influence today
6:30
_All_ dinosaurs, Dave?
Then what are birds?
Great video, but I think you should have brought up that some avian dinosaurs survived the mass extinction and evolved into birds.
These avian dinosaurs were already birds as we know them! Only a few lineages survived and they form the diversity of birds we know today. It’s possible a few toothed birds survived but they clearly died out in the early paleogene.
I'm curious, how did dinos evolve and split between reptiles and mammals?
The craziest fact about the Great Dying is species of Earth still haven't rebounded from the diversity lost in Families of the animal kingdom.
Can you do a video on Flat Mars as Mars is also a flat domed world. I proved it!
Your joking right
@@Lumalee Welcome to flat Mars!
rip dinosaurs
Dang young earthers are mad in the newest first
"An asteroid equivalent in mass to 50 million titanics"...
Americans will do ANYTHING to avoid the metric system!!
😁
Reject grams and meters, embrace rock and someone else's feet.
Wow wow wow wow wow
that's an amazing amount of Titanics
Haha, you got that off the latest Answers with Joe, didn't you? Made me lol again
Dinosaurs are still living with us. We just call them birds! They might lose their foothold on land but they are still dominating the sky!
When i say to yoi subscribe i get many things before i dont
Zoology is pronounced zoh-ol-oh-gee. There is no zoo in zoology, is a good mnemonic to remember it that my teacher gave all his students.

3rd comment
I've studied the Chixculub (hope I'm spelling that right) impact, and it seems to be the most devastating meteorite impact the Earth has ever experienced. How could an impact of that magnitude not completely sterilize the planet?
It wasn't the worst though.
Worst extinctions happen when there are long-term effects affecting the atmosphere, like great oxygenation event or mantle spewing lava and CO2 continuously for millions of years.
While Chicxulub most definitely did kill off majority of large land life it is now more predominantly thought that it was the Deccan Traps was already playing a role toward saturating oceans and atmosphere with CO2, also becoming more active around that time (unknown if by consequence from this or some other impact, but seems unlikely).
Keep in mind that while Chicxulub was the largest crater of that time we've found it's also very likely it wasn't the only one either.
It was the last of multiple global extinction events, each of which exerted pressure on surviving life to be less susceptible to THAT sort of event’s aftermath. Basically, life is getting tougher and more adaptable.
The Big One was The Great Dying, associated with the Siberian Traps tectonic event.
No no no noooooo!! The earth is 6000 yeaaars stoooooppppp!!!!!
😂🤣🤣🤣🤣🤣🤣
Good one.
Always appreciate a good laugh 👍

Good video but dinosaurs definitely survived the mass exntiction and are widespread throughout the world, we know them as birds.
All dinosaurs except the avian ones went exctinkt
There's even a theory that the Loch Ness Monster is actually an Elasmosaurus (an aquatic dinosaur) that survived the extinction
@@flatearthisahoax4030 elasmosaurus isn’t a dinosaur and that theory is more of a conspiracy theory, there’s no reason to believe it’s even remotely accurate.
All dinosaurs were extinct??? Or just all non-avian dinosaurs?
Non-Avian. The Avian ones are birds! Which yes, Birds are dinosaurs!
@@lcx1876 It was definitely 66 Million Years ago, more presicely 66.03. We just had a new paper come out this year on the KPG Mass Extinction :/
@@lcx1876 Most of the time things are consistent. Science changes. Also, aren't you just doing the same? Taking your "evidence" from a book that was mangled by over 50 men over 2,000 years to control peasants and they claimed it was the 'word of god'. You're no different. If an asteroid hit the earth that soon, we wouldn't be alive because nothing larger than a house cat survived.
@@lcx1876 no we believe what we have evidence for. Go look at the data yourself
4:02 "americans will use anything other than the metric system"
(this is a joke and i find it hilarious)
Repeating my pseudo-poetic comment from the last episode... It's oddly beautiful that the largest mass extinction was the precursor to the era of giants, the era of dinosaurs.
I guess that leads me to a question...
What is your take on speculative biology--the offshoot of alternate history that focuses on what life would be like if certain geological events didn't happen?
The Great Dying 2: Humans are too busy
Plot: A super volcano erupts triggering the second coming of The Great Dying and we're reminded of all the shit (mostly The ism) that kept us from protecting our species from extinction...
Hello, I’ve just come from your annihilation of dave the douchebag ‘flat urfer’
New Subscriber, great job Prof Dave🙌🏼
I love dinosaurs. They're just giant birds
You planning on getting that Chemistry Jesus hair again, or are you keeping it short? I always thought the Chemistry Jesus style made you stand out from other science channels.
If I ever become a successful musician again I will grow the hair back out. Maybe.
@@ProfessorDaveExplains any thoughts on content for the structure & reading for music ?
Yes I will do a lot of music theory content one day!
Ain't no way 💀
DINOSAURS
I hate to be that guy, but you made a mistake. A BIG mistake.
Not ALL dinosaurs went extinct. Only the NON-AVIAN dinosaurs went extinct. Birds ARE dinosaurs, and last I checked, they are still extant.
