I used to like always hearing about dinosaurs when I was a kid and would only briefly read about mammals and their relatives. Now I can't get enough information about Synapsids and their descendants. Love videos on the Permian period and the Cenozoic periods and epochs.
Same
Literally me, I just find the synapsids so interesting as they now have conquered earth twice now
5:02 jeebus chris that guy is going to haunt my nightmares. Most terrifying recreation of that beast that I’ve ever seen
Imagine seeing that in real life tho...
The communal latrines made me think about Indian Rhinos and their behaviour.
Another excellent, informative and visually appealing video.
If I could travel back in time I would love to go to the post Permian extinction event and see the massive herds of Lystrosaurus grazing on the fern prairies. What a sight!
I'm coming with you! 😀
You're an absolutely amazing source for information about prehistoric life, thank you for making a video on Anomodonts! Perhaps do a video dedicated to another group of more derived Therapsids next, the Therocephalians.
I’ll definitely be covering those groups in the near future.
@@dr.polaris6423 Thanks, oh boy am i excited for that!
I was wishing only yesterday that you would make a video about these! And... here it is!😮😃 😍😍😍
Ever since I first saw Walking with Dinosaurs, I have been curious about the dicynodonts and their kin. I don't know why I find them so interesting. Maybe it's because their skeletons look coarse and clumsy and yet so powerful. That they were here, where we live now, and that they managed to spread out and stay for an incredibly long time. To think that Lystrosaurus was nearly everywhere in the world! Was there a shortage of predators? Was it the food? Nature seems to have kept its balance even though there were so many of the same kind. I wonder...
Thank you for a very interesting and educational video, from a paleonerd. 😍
Another great video from you about this fascinating lifeform. 🥳 One reads and hears a lot about dinosaurs, but little is known about these exciting synapsids. 🤷🏽 I celebrate this part all the more and thank you for the contribution.
If I had a time machine, I would actually like to see the Lisowicia in the Triassic. Exciting. 🤓
hearing the music always brings a smile here:D, the most dangerous animal here is a mousquito, the largest a cow, call me happy:D but it would be amazing to be able to see it all for real up close. what an amazing animals there have been. thank you dr polaris, respect for your work!
Lisiowicia alongside Smok are probably the most iconic Polish mesozoic fauna.
You forgot about Silesaurus and Polonosuchus.
And both from the same neighborhood in Poland, right?
@@mikesnyder1788 Yes, Lisowicia and Smok were contemporaries from the same time and place.
@@eybaza6018 What a treasure that must have been when the diggers came across these fossil. Thanks and regards...
@@mikesnyder1788 No problem!Bad news though: due to a brick factory contract expiring in 2017,wich previously used up a lot of water now with nothing to prevent water from accumulating most of the Lisowice dig site, wich is located near the brick factory got completely flooded and the current landlord can't do anything about it...
Thanks Dr P, so much more surely to learn about the synapsids in this time period, great to see some really great creators with a true passion and appreciation for the history of life beyond the mainstream dinos and creating awareness for all these major times, many thanks for putting this together
Hey man, love your videos as always. I was curious if you'd ever cover the oreodonts at some point? I feel like as common as they are that they get overshadowed. Been seeing some recent stuff on some species possibly having small trunks like tapirs?
A very good, well-made, informative, nice and enjoyable video as usual ! 10/10 👍
But, this time, maybe one of the best of your channel so far !
Not only covering the best, most famous and beloved Dicynodonts themselves, but also their relatives outside them, the members of the super-order in which Dicynodonts belong themselves !
Since they are often shadowed by these latter and not often put in front of the screen.
All of the famous and unavoidable genus/taxa are mentionned and presented as they deserved and in all their greatness !
Diictodon, Roberta, Lystrosaurus, Placerias, Kannemeyeria and Lisowicia.
All important members and type members showing the overall evolution line that they undergo.
From small generalist burrowing species from the Late Permian that survived the famous Great Dying Extinction even to medium sized herbivores fitting the Ungulate niche during the Trias, to the specialized Elephants sized members that held on to the end of this first Mesozoïc era !
Dicynodont see their Golden Age from the very beginning of the Trias, and undergo a quick and high radiation.
Being two of the only Synapsid/Therapsid along the Cynodont to survived the Permian Extinction, the worse extinction of all that Earth herself has known.
They held on during all the Trias, coexisting with the numerous herbivores archosaurs like the herbivorous crocodiles Aetosaurs (Aetosauria) and the herbivorous members of the Poposauroid, with the Sauropodomorph and Prosauropod dinosaurs like Plateosaurus, and the Silesauridae.
Suminia is also mentioned as it deserved, being the oldest know definitive arboreal animal and one of the weirdest and oddest creature of the evolution and the Permian era.
It's was a primate long before primate were a thing !
I praise this episode !
Very odd animals that we probably reconstructing wrong. They were very weird creatures that were adapted to the hot deserts of pangea
5:01 - Good gods, that’s Nightmare Fuel.
those suminia are going to haunt my nightmares
Thank you. Very informative and enjoyable. Have you ever considering re-doing some of your very early content?
Amazing how much time we've missed out on. If not for people like you, we'd not have a clue what happened and when
I was getting some major King from _The Owl House_ vibes from the critters in the thumbnail.
Wish they were still here
If Dicynodonts never got locked to the large herbivore niche and some genera still stayed small generalists they may have survived until today.
The next De Loy's Ape video will be very interesting, being one of the famous cryptids that was recorded and the most well known hoax ever revealed !
Being at the same level than the iconic Loch Ness' Monster or Kasai Rex case !
Amazing video.
I would say that Dicynodonts weren't very common in the middle permian and only found major success in the Late Permian in places but they weren't the dominant herbivore, Pareiasaurs were also quite popular being large in the Middle Permian (Bradysaurus) and the Late Permian (Scutosaurus). Even then, the largest of the Late Permian Dicynodonts was Rhachiocephalus, of which I will admit is very big but isn't nearly as big as the Late Triassic Lisowicia which you displayed earlier when discussing Permian Dicynodonts.
Dicynodonts probably exploited the extinction of Tapinocephalids and basal Anomodonts.
Thanks doc
Ah DeLoy's Ape, Trey the Explainer did a pretty good vid on him. I can't wait to hear your version of this cryptid's wild ride.
Really enjoy your videos Doc. Is it just me or do some of these Dicynodonts, especially the smaller herbivores, look like they could potentially be cute, cuddly pets? Especially if they had more hair or fur... I know, I'm weird! LOL
😆 🤣 😂
Another first rate video, Dr. P. I liked it so much I am watching once more. Just a few years ago I knew virtually nothing about Synapids and the world in which they lived. Keep these videos coming! Kind regards...
Finally! A new video!!!
Fascinating! I had no idea this sort of animal was so diverse!
Would you consider doing a video on the evolution of garfish or sturgeon?
I like how these videos emphasize that just because a group of creatures went extinct, that doesn't mean they were failures. All species die out or change into new ones eventually... let's see if our species manages to do better than Lystrosaurus. 😛
NICE
Also successful in the Triassic.
DeLoy's Aaaaaape!!! Nice!
the art at 5:00 mins in is nice & spooky.
Assuming you haven’t yet, Are you going to do a video on Tyrannosaurus and it’s relatives?
Dicynodonts have long been my favorite extinct critters. My only complaint is that you didn't mention Bulbasaurus, if for no other reason than it having a top tier name.
Its A shame this video didn't focus on Permian Dicynodonts too much like the ones from Russia and Geikiids, especially Rhaciocephalus.
this has been a great weekend for me. I've seen Puss in Boots the Last Wish, Michael Kovach liked the tweet I made about him where I called him a legend, and the great Dr. Polaris posted a new video. I've already seen TREY the Explainer's video about the De Loys' Ape years ago and the main thing I remember from is that George Montandon was a big supporter of racism and anti-semitism and had an mess up view of evolution.
I wonder if they got the chance, would they eat a small animal?
whats ur intro song
I'm thinking more and more that Therapsida (leading to us) and Archosauria (leading to modern birds) are cousin groups who have more similarities than differences next to modern derived reptile sauropsids and extinct basal reptile adjacent synapsids....
They aren't 'cousin groups' and 'reptile adjacent synapsids' is obsolete.
@@Dr.IanPlect They are still remote cousins in the diverged sauropsid and synapsid families, with some stark similarities through convergent evolution (and people fucking love to keep on ignoring the essentially reptile like form and function of basal synapsids stem-mammals).
@@TedShatner10 Your revisions are corrections I already indicated.
It's fascinating how two groups on the opposite sides of Amniota converged so much, raised metabolisms in most cases, more erect postures and in some cases among Archosauromorpha heterodont teeth in animals such as some Notosuchians and non-Avian Dinosaurs.
@@eybaza6018 That's why with speculative evolution projects you get pterosauria, alongside avian and non-avarian dinosauria, carry on evolving past their already pretty therapsid features from RL until they have species with most or all crown mammal traits...
Right after the Cryptid called De Loy’s Ape, why don’t you also get to make a suggestion to create the UA-cam Videos Shows about the evolution and the history of the Extinct Prehistoric Marine Or Sea Crocodile Species, such as Thalattosuchia, Metriorhynchidae, Teleosauridae, Geosaurinae, and Machimosauridae in the next couple of weeks to think about that one coming up next?!⭐️⭐️⭐️⭐️⭐️👍👍👍👍
That’s a great idea!
Synapsids, Reptiles that design to survive in the Pangaic Wasteland.
Diapsids: Advantageous Reptiles that been lose dominance after an space nuke land in Mexico.
Mammals:From the Reptile group called as Therapsids, they're are adaptable in all climates.
hippo tortoise
They were essentially primitive versions of the Capybara, the Wombat or even the Hippo if the hippo and capy were mostly terrestrial.
Volume is far too low.
Question about synapsid:
Does dimetrodon,gorgopsid,& cynodont have ear and fur like mammal?
And does they giving birth or lay egg?
Therapsids may have had some kind of hairy coats, particularly in smaller forms. They almost certainly laid eggs, while their ears were moving towards the mammalian condition but lacked external fleshy ear flaps.
@@dr.polaris6423 does therapsid drink milk like mammal?
@@jasminegobuster3847 I don't think there's direct evidence for suckling of any sort in these proto-mammals yet.
Indirectly speaking, monotremes do produce milk and some have argued for their divergence from other mammals being as old as the Triassic, what would imply that at least some branches of these synapsids, the ones more close to mammals, probably had already began producing milk as well in those days. But rather than these dicynodons, I'd look in the group of furry burrowers like the cynodonts, which are presumed to be ancestral to us (and all mammals in general).
@@jasminegobuster3847
No they drink milk like teenagers 👈😑
@@jasminegobuster3847 as far as we know milk production evolved much much later on, being a key mammalian feature. Though perhaps it was in the process of evolving
Good god, Dr Polaris! Not the bloody De Loy's Ape! Please don't try to scare me, lad. You are going too far. Cheerio.
I’m a bit confused, did I miss the part where these animals are described as mammals, reptiles or something else?
They are neither, they are synapsids. Synapsids are the lineage that mammals evolved from, mammals are synapsids too, but Dicynodonts aren't mammals.
Dicynodonts
Couldn't get a decent scotch until the Pleistocene in my experience 😕
Anomodont Doo dooo do do doo
Love to catch up. So it was a fraud
