This video looks into the evolution of dinosaurs and answers such questions as what is a dinosaur? why do most dinosaurs run on two legs? among others. It takes place in the triassic which is one of my favourite geological periods to study as it has some fairly strange animals.

Definition of a Dinosaur: en.wikipedia.org/wiki/Dinosaur
I thought I would re make this video seeing as the narration on the old one was trash. However, I’ve added so much stuff and better visuals it’s basically a new video so hopefully everyone who watched the old one can still enjoy it.
Moth Light Media I thought it was good! 👍
Keep up the good work mate. Love these videos.
@@radical-faceplant thank you
You videos are very informative but you should speak more distinctive and a bit slower. ;-)
Actually: your narration doesn't need to be slower, it just needs more melody; go up in the beginning of a sentence, and wind down at the end, to make a full stop. Love your content, you deserve more followers, so it deserves an upped narration ;-)
Crocodiles are a very interesting group, always holding the semi-aquatic ambush predator niche, but branching several times into others as well.
Only to get absolutely body slammed by new competitors that always do much better than them for some reason.
@@tozarkt9805 They got banned during the Triassic, when they had the most builds along with early dinosaurs and again at the end of the Cretaceous with plenty of other existing builds, the only one remaining is the aquatic build, similar to how the only dinosaur build left is the flying one.
@@arnigeir1597 There was an explosion of diversity after the cretaceous though, with about 80% of pseudosuchia (the group that includes modern crocs) sailing through. Up into the eocene, some were even the apex predators of europe at the time. But then mammals moved in, and here we are.
Not always. Before crocodiles, there were phytosaurs and some other groups.
@@tozarkt9805
This is a myth. The rauisuchians and other land-based pseudosuchians went extinct due to the End-Triassic Mass Extinction, and there were plenty of cases where terrestrial crocodylomorphs coexisted with dinosaurs or mammals WITHOUT getting outcompeted.
and they evolved wings and became the most diverse group of terrestrial vertebrates alive today. Its kinda mad just how successful dinosaurs were and still are
@Svoon V ... no. They are, it's just a fact
@Svoon V the only vertabrates more diverse are fish and probably the most primitive forms of vertebrates
@Svoon V Birds are primo, coming to think of it, they occupy an immense amount of vertebrate niches, seems like the vast vast majority of flighted niches, with the exception of a couple species of bats.
@Svoon V Most all paleontologists agree in 2020 that birds are theropod dinosaurs.
@@williamjordan5554 it’s sort of obvious just visually. Bird legs and feet are theropod legs and feet.
Would love to see a video describing all the periods and extinction events in-between them!
Here is one

@@siddharthbirdi thanks
This is some serious quality content.
Thank you I appreciate it
More than quality content if all vids are being combined and form a Doku then it could win a Oscar with ezzz
Absolutely beautiful and valuable content indeed 🙏
@@lexobischof7069 this is way to good for the oscars lol.
You're damn right
Ancient Earth was more alien-like than the ones shown in sci-fi movies.
That is one of our greatest flaws in depiction of alien worlds. Our imagination, however wild, can’t go beyond earthly experiences
If we can travel back in time to beginning of Triassic period. Earth look very different than today. We probably think are we still on earth, or we landed on some other planet.
Being massive is a real evolutionary gamble. It can make you the apex predator and the top of the food chain, but if some mass extinction event occurs, and the food sources are interrupted, enormous predators will not be able to find enough food and die out, while smaller creatures that require less food will survive. Our reality is so fascinating
In 8 minutes you’ve taught me more about dinosaur evolution than 12 grades of public school and a few semesters at college. Great content, I had to sub so I can be sure not to miss anything!
Did you take any classes specific to dinosaurs, their evolution, or fossilized remains?
1:06 Weirdly, the animal in that image most closely related to modern crocodiles and alligators is not actually the one doing the biting (which is a phytosaur), but the one being bitten.
That’s so interesting, thanks for sharing. Crazy how evolution can divert one animal in so many different ways
@@kanyesmemeemporium836 Yeah, the niches in particular ecosystems are so specific it's almost like actors filling a role, and the minute it's vacant a new actor steps into their place to play the character. The crocodile niche is such a fundamental strategy that it always pops up. The role of a semi-aquatic ambush predator requires more brawn than brains and is usually in a warm environment, allowing what seem like living fossils to maintain their grip on it while being cold-blooded and relatively unintelligent compared to mammals. They just perfected it and held onto it through multiple mass-extinctions without being dislodged by other species. They stuck to what works rather than fixing what isn't broken.
Yeah. Phytosaurs and modern crocodilians only resemble each other due to convergent evolution.
I'm glad I stumbled upon this channel. I am now watching all of your uploads. Quality content all around.
Thank you I appreciate it
3:21 I remember that picture of fighting Allosauruses from a book when I was a kid back in the 70s... memories...
You could crop the image and search the image itself so that it would reveal similar images by the artist or book.
Recognize it too. Looks like a screen shot from a dino porn movie
Playing not fighting
@@williamjordan5554 Yes... Allosaurus does translate to "Playground Lizard"
@@sdarms111doug9 Silly. Birds play the exact same way, and the pic seems to show juveniles.
Me: Reads the title. Checks length of video. Yeah right, it really can't be explained well in that short of time.
...OK, you did it.
Studying palaeontology (like Law) I bet must be a real headache as the textbooks must be overturned so often with new discoveries / new categorisation shifts etc.
Indeed. It can be hard to keep up with if you don't know where to look.
You get used to it after being a biology major. It’s part of the fun.
well there would be no money to be made if everything stayed the same, each major discovery could be seen in some scientists eyes as a possible payday
I love your videos, but I think this one is my favorite. It does a fantastic job of uniting two complex ideas: the timeline of ancient earth, and the proliferation of the tree of life. Both are huge concepts, but when put together like this it creates something truly special.
This video gave me just the right information that I wanted and I learned a lot from it. Thank you!
Wow, what research, how informative is this and like how you put it in a smaller amount of time, just started watching your shows 5 days ago and seen 16 so far,a bit addictive if you into this stuff and keep them coming.
Your channel is awesome. I love listening to the info you provide for us. Keep up the good work bud!
One of the best channels on you tube
Thank you for all the work and quality!
A video about the creatures that lived during the Permian and the Carboniferous would be great, in particular the Synapsids.
Btw, your channel is younger than I thought, with such a good content I imagined it was at least 4 or 5 years old.
Keep it up! :-D
Really liked this video.
New subscriber here, thoroughly enjoying your work! Since you mentioned them, I'd love to see a more detailed video on the various bizarre Triassic pseudosuchian lineages, as well as the synapsids and perhaps the more basal archosaurs (assuming you haven't covered those already and I've just not seen the videos yet).
I am in love with this channel, do not know why, but
1:41 bro at that point i have bigger problems than what sort of animal it was that got me lol
This channel should have way more subs
Damn! This channel doubled its subscribers (10k to 20k) in less then a week! And deservedly so!
My left ear loved this video
Once again, highly informative. Thank you!
Subscribed so fast
Anyone know the name of the song used in the background music plz :( love your vidz btw
Great video, love your content! 🦖🦕😄
Thank you
Great Video! what is the background song?
Excellent videos - informative, charming, and with a nice touch of understated humour. 1:42 "If you travelled back to the early Triassic and were eaten..."
Dinosaurs and crocodilomorphs have a one way breathing system just like modern varanids. I can imagine a large Allosaurus taking deep breaths and hissing like a Nile monitor.
Or chirping like birds 😂 considering that dinasaurs are what get served on your favorite kfc menu
what's the music being played at the background? sounds really nice
I never get tired of dinosaurs!!
Great video sir
Thank you
Nice video
I love this guy's voice
At 0:35 in this video you showed a picture of Sharovipteryx. Very interesting! any more information? I would like to know more. Thanks for your videos!
I second this!!!
Pls do a video about rauisuchians
I will never give up until you do it
Reverse pterosaur?! 8:40 can we get more details on that?
Suggestion for one of future videos - Erythrosuchus.
Thid is quality stuff
3:22
"TICKLE MONSTER!!"
"BAHAHAAHA NO MOM STOP"
I’m one of 6 thousand people who have subbed in the last day. Now that’s exponential some growth
Tortoises survived the extinction also amazingly
I subbed a week ago and there was only under 15k subs 😵😵
Could watch these for hours
Me too!
The Great Dying was one of the craziest events in Earths History imo.
I miss this music in your recent videos
Crocodiles are so nice just chilling in the water and eat stuff
Does anyone know what song is playing in this video
Cool
Love it!
This is the most positive comment thread on RUclips and I love it
Why would some people think dinosaurs were fake
people who didnt go to elementary school
Maybe it's because people think the fossils are fake
I would love some more videos on Triassic wildlife
3:21
Those two be:
"oi you fuck head how dare fart on my face ur dead you butthole"
"Ayyy lmao thats going in my braap collection"
Same question what was their 1st form?
Technically there wasn’t one, evolution is gradual. But something superficially similar to a basal theropod or really basal sauropodomorph.
Make a video about crocodiles being herbavores and being bipedal
I'd like to see a chronological breakdown of what ruled (on land) and when. I'm assuming amphibians took over first but I'm not a good judge of when and the general order. You have taught me that aquatic crocodilians are the supreme lifeform and will probably wait for the last of the stray humans at the riverbanks.
"I'd like to see a chronological breakdown of what ruled (on land) and when"
- 6 months later, have you done so?
"You have taught me that aquatic crocodilians are the supreme lifeform"
- how are they 'supreme'?
Whenever I watch dinosaur history things I feel sad bc I wish they are still here
25 people who disliked are creationists. Who think that Evolution don't exist
Creatards*
I really thought for a second that the thumbnail was a sabertoothed tiger humping a dinosaur
dinosauromorph: stem dinos
What about pterocuda and sharktopus ?
And, of course... crocoduck...
1:04 also the thumbnail image: does anyone else see the silhouette of a lion made by the right tree branch?
Ok, "reverse pterosaurs" is jut the best epithet to the Sharovipteryx.
Could someone please tell me the spelling of the name of the “reverse pterosaur”?
Sharovipteryx
Gabriel Valeriolete thank you very much
Ruasoretp
Now i know many triassic creatures
Could someone repeat the name of that backwards pterosaur for me? Never heard of it... Auto-CC calls it Shera Victor X, which obviously yields not quite right results in Google
sharovipteryx
T-Rex are so funni, i mEan how do they get back up with dem lil arms?? haha
Same way birds do.
Go take a look at the Carnotaurus lol
.... Very soothing voices suited for topics like this, make me go brrrr
God I love your Vids even if it’s a little hard to understand since German is my mother language still high quality content :)
Its sad how the only descendants of the archosaurs today are only crocs and alligators
And birds
My fascination with dinosaurs is mostly from the strange similarities between our bodies and bipedal dinosaurs. The two legs and two arms with grasping appendages. Looks like something out of an Egyptian deity.

I'd like to think that I'd know if it was a dinosaur or an archesaur eating me.
5:31 what is the dinosaur here i want to know its name but i cannot find it. The captions just say chromakey Saurus i'm so confused help
en.wikipedia.org/wiki/Chromogisaurus
So how did the crocodile lineage survive the KT event when pretty much every other line became extinct?
Oddly, there is a trend showing that a number of freshwater animals weren’t significantly affected by the extinction event.
Love these videos!
Sadly, I must opine that this current electronic epoch will be totally erased when the lights go out.
1:01 can you find the bear???
NEW SPECIES OF RUclipsR DISCOVERED: 'Paleotuber' Theres another species of Paleotubers called 'Dinotubers'
Scientists: “We will call it: tyrannoarcheoptorguanapterocopterixodosaurus rex which means large toothed asshole in science. Though we can just call it a T-rex for the sake of time.”
Tyrant ancient dragon wing tail feather reptile king, would be an accurate translation of that name, but we can still go with T rex.
Animals before the dinosaurs are pretty interesting
I wonder how bipedal mammal predators would have evolved
You ARE a bipedal mammal predator
@@Chris-ib5ht You know what I mean
@@daniels7568 well don't really have bipedal mammal predators, but we have Kangaroo with a similar body structure to therapods and we have the bipedal rodents in the Dipodidae family
You wouldn't know if you were eaten by a dinosaur or a croc. 🤣
I used to have dreams were I was chased by prehistoric creatures. Seems like they're memories from distant past, when we lived in fear.
When you blow up don’t forget me
I sometimes get the feeling that the triassic era was like audition time for reptiles so they could see who would win😂
Ahhhh! The hoofed bipedal crocodile terror and the Hell Pig all in one video.
Click bait!
**clicks thumbs up**
Want to be a legend?
Hour video on Ceratopsian evolution, fifteen minute minimum on Triceratops for "reasons", and the injustice of the universe for their extinction.
I can hear the 'video is too long bro!' crowd wailing because they would be unable to quit watching and the pain of sitting still for more than five minutes is abhorrent I hear. ;-)

No! Iguanadon was named by somebody named Gideon!
Yes, Gideon Mantell.
I like the idea of a reptile uprising- legion after legion of iguana streaming down the from the volcano's cauldron
How did 25Ft massive T-Rexes. Devolve into a chicken?
Trex didn’t evolve into chickens, other raptors did, trex died out bc it was too big and needed too much food during the Cretaceous extinction, so being small is just as much an advantage as being big, it’s all about context. Saying that larger animals becoming smaller is devolution is a misunderstanding on how evolution works, there is no plan it’s just simulated randomness in nature and organisms finding niches that let them reproduce the most. For instance chimps aren’t the devolved humans, they’re equally as evolved as us, just great apes who evolved different traits because human traits weren’t beneficial in jungles, like bipedalism.
tldr; nothing really devolves and there is no end goal of evolution, that’s just us humans searching for meaning where there is none
New video idea: "how dinosaurs f###d up and died
It was much later when humans devolved.
Man, i love your videos, i really do. But you sound like you're about to pass out in this one. I have to turn it up so much just to hear and make out what you're saying. I feel like your vids could benefit from a bit of an audio clean up, particularly in the lower mid frequencies (bass). I'm a sound tech, can do it for you if you like.
Thank you for all the awesome vids on all the cool topics.
were archasaurs Reptile?
yes.
only living archosaurs groups today are birds and crocodilians
