Technically, Dimetrodon is closer on the tree of life to dinosaurs then primates are to turtles (both reptiles, evolved from same reptilain ancestor as dinosaurs, both typically cold blooded.)
@@amyjoneswilliams Possibly, but Dimetrodon is a synapsid, sure its not a true mammal in the traditional sense, But the fact of the matter remains that it is still a synapsid, not a diapsid like reptiles, birds, or dinosaurs. It has two holes on it's skull and not four, just like us and other mammals. Plus dimetrodon had different layers of teeth, it gave way to the diverse types of teeth different mammals have today, While reptiles still have rows of teeth that are identical to each other . Also dinosaurs are not cold blooded, its been a known fact for a while. If people still believe this shit that they are cold blooded, then they should do their research. Not directing at you, just people in general😁
@@amyjoneswilliams Dimetrodon was not a reptile, despite being often called by the old-fashioned name "mammal-like reptile". A more accurate and modern term would be "non-mammalian synapsid". It doesn't really fit in any of the traditional tetrapod taxonomic classes (not an amphibians reptile, bird or mammal), so its just called a pelycosaur synapsid. Yes, it was probably cold-blooded, scaly and most likely egg-laying, but it only had one skull opening, just like mammals. Also, the common ancestor shared by dinosaurs and pelycosaurs were primitive, lizard-like amniotes from the Carboniferous. The earliest reptile, Hylonomus and the earliest synapsid, Archaeothyris, both from the Carboniferous, were very similar to each, and they both looked very lizard-like. So they actually did not "evolve from the same reptilian ancestor as dinosaurs" and their ancestry dates extremely far back, up to 320 million years ago.
It's almost unfair that we won't ever even begin to know everything, that potentially spent millions of years playing out it's own unique role in this existence, that we all probably just "lucked" into.
Synapsids like Kannemeyeria and Cynognathus also lived alongside the first dinosaurs. Dimetrodon died out about 30 myr before the Dinosaurs, not 40 myr as thought.
I'm not sure about that. I do know that the Cynognathus was contemporaneous with the Erythrosuchus, a large archosaur, but not a dinosaur, and the related Euparkeria.
A good video, except for one thing. Grass is a flowering plant. Flowering plants didn't evolve until the Cretaceous Period. Therefore there is no way that Placerias, a Triassic animal, could have eaten grass.
Yaa, Flowering plant are evolved in Cretaceous period only but before gymnosperms plant appeared it was dominent in mesozoic era but it was appeared in Permian period of palazoic era ......... So in Cretaceous period they can eat gymnosperms , brophytes plant also nhh ...............

I think I would rather see what the earth was truly like hundreds of millions of years ago than see if there is life on other planets or if there is anything after we die.
I feel like estemmenosuchus and animals with similar boney structures probably had some kind of soft tissue thing going on, maybe a resonating chamber, maybe even something reminiscent of a trunk. There's alot of things like this in the fossil record, imagine if we didn't know what dugong, or hippos or elephants looked like, but found fossils. With all their unique soft appendages and organs and stuff, we'd depict them quite differently if we just had bones
the protrusions are too thin, long, and smooth to be muscle anchors, also, if you were to infer tissue based on the placement if these bony parts, they would cover the eyes.
10:32-10:34 wait hang on, did he just say eating grass? Hold up, grass didn't evolve even towards the cretaceous period, how the hell would grass exist in the Triassic, let alone the Permian? something's fishy here.
First video and already subscribed. Nice job. Try and do it with your own voice. I don't sub to machine voice channels, but yours is too good to ignore.
ok but why in the world... does it say cheese.... i thought the thing in quotations was what the scientific name stood for. but i looked it up and Casea broili is named after E.C Case and Ferdinand Broili so like, is cheese the common name? how in the world did it get named cheese
In the thumbnail image. What is the name of the animal in front of Lystrosaurus and Dimetrodon? It didn't show up in the video. It looks like a komodo dragon with hair like modern hyenas.
live birth is almost exclusively a mammal trait, mammals have developed this way of birth because it made it less likely for dinosaurs at the time to eat their eggs.
we don't know for sure if they had visible ears since they don't fossilize, but we can at least assume that the more advanced synapsids aka therapsids like cynodonts probably have them
Hell to the yeah! I need to revisit paleontology. So much I hadn’t seen before in here. I know there would be more than a few volunteers to narrate if you wanted to drop the voice-bot. Just sayin
@@hansunwoojett synapsids were never true reptiles, even if they had very similar features right after the split from other amniotes. Similarly, the extinct anapasids (or parareptiles) were not true reptiles either. Only the diapsids are the group considered to be reptiles, which by the way includes birds.
I agree. The use of a computer voice makes the whole presentation difficult to follow, as there's little to no intonation to emphasise the more interesting or difficult parts of the story. Everything simply progresses at the same monotonous pace with a lot of scientific names and tiny facts - if any - about specific species. Although there's no doubt a lot of information in this presentation, the way the data is presented makes the story hard to follow. And then I don't mean the visuals - which I find quite fitting and attractive - but rather the lack of intonation and story-line. Now its basically just a parade of species, graphically linked to one another, but without any connections otherwise expressed. As context frequently helps people remember, I think this is something this video could have certainly profited from.
@ though, 1 criticism at 10:30 you say placerias fed on grass, but grass wasn't around in the triassic, and only evolved after the end of the cretaceous

You're right, I was thinking of plants on the ground actually, like moss or small kind of ferns
10:15 Kannemeyeria = Kannemeyer's one.

There was no grass back before the late jurassic, so none of these creatures would have eaten grass on the banks of rivers. Ferns and cycads, yes, Small conifers, yes. Grass, no.
I promise you, no matter how bad you think your voice sounds on recording, no matter how inexperienced you might feel doing narration, the viewers would 100% rather hear a natural speaking voice. The artificial narration is very off-putting. If you had access to the analytics to see how many viewers only watch the first 10 seconds and leave, you would believe me. There's a science and futurism channel where the creator does his own narration despite a mild speech impediment, and over the last several years his speech has drastically improved and his view count is steadily climbing. We really don't care so much about the voice and pronunciation of a real human. But this jerky robo-voice is like being stabbed a thousand times with a tiny needle. Please... just talk to us
i think the reason why extant monotremes are earless because they are descended from aquatic ancestors that lost their external ears because of their adaptation to aquatic lifestyle
its mass extinction event that wiped out around 96% of all marine species and around 70% of terrestrial species(including plants and insects) it was during paleozoic era 250 million years ago. its most severe extinction event ever recorded most probably caused by severe volcanic activities.
@@khinchandara926 I don't see how one is more difficult than the other to understand. When you learn the lineages of each, they're equally straightforward.

So wait were synapsids a type of reptile That lead to mammals or were they reptile-like animals that lead to mammals
Mammal-like reptiles that got more like mammals over millions of years of evolution.
Ok I thought so thanks for the re-confirmation. I just got confused because people stopped referring to them as such
Synapsids aren't reptiles.

Does synapsid have ear & fur and giving birth like mammal?
we dont know if early synapsids had fur, but one was found with skin impression and it had smooth gland filled skin.

It seems likely that synapsids would have atleast have leathery skin or a slight fuzz

if dinos are reptiles, were they cold blooded and prone to sluggishness
when the environment temperatures dropped - sort of like snakes ?
The ones that were cold blooded would definitely be more inactive unlike the warm blooded dinos
Castorocauda adapted aquaticism long before mosasaur ancestors did, could such cynodont descendants rivaled mosasaurs as oceanic apex predators?
Why do all the later cynodonts have external ears. I thought that was unique to therians. Or at least appeared after they split from monotremes.
