As I continue to go through the comments of my videos, another topic that I have seen a large amount of interest in is the subject of terrestrial crocodiles. This was all in reaction to one comment I made about them that has been viewed with anything to fascination to horror at the very idea of a "land croc"
The thing is, not only have land crocs been a thing once in the distant past, but it is a phenomenon that has existed several separate times in the 250 million years that crocodilians have been around! So I decided to make a video covering their history to act as kind of a fill in for my History of the Earth series. Because even though some of these animals might be mentioned along the way in those videos, there is no way that I will be able to cover them in as much detail as I can in a dedicated video.
Also this is going to be the first Paleo Analysis 2 parter! With my next video covering the most recent land crocs that have existed on Earth, the Australian Mekosuchids!

I'd selfishly love to see a deep dive on the Terror Birds purely because they represent a real gap in my knowledge.
Not really selfish after all you suggesting content that helps the TH-cam
Also I want that bud two
Phorusrhacids definitely need better representations and need the credit they should have. They are very amazing animals and generally very misunderstood as small game hunters, living alone and only peaking stuffs while they were able of much more as top predator of their environments.
Do you want nightmares? Because that's how you get nightmares.
Yes!
They’re criminally underestimated even in documentaries.
I like how they aesthetically range from adorable to terrifying
Just like modern crocodiles really
I know! Simosuchus I don't think I knew about, but I rewound just to aww at it
@@mariomouse8265 How are modern crocodiles adorable ?
@@okantichrist have you seen a dwarf caiman? adorable!
Very much agreed! I wish I could have a pet pug-croc, and I'm not even that fond of pug dogs!
As an Australian I am sad that you stopped the video right where you did, but also pleased we get a whole episode.
I'm sure it'll be worth it once he goes indepth about how Australia managed to evolve upside-down crocodiles
A very excited fellow Aussie here, looking forward to part II...
Australia is so wild. I love learning about it. 😁
You could tell me it was some far away planet in another galaxy. And I'd be like, _yep. sounds right._ 🦘
Aussie Aussie Aussie
Oi, Oi, Oi...
It's crazy that even though the cenozoic is the rein of the mammals, the largest cenozoic carnivore is actually a reptile, in both length and weight.
It's just mammals who claim it's the age of the mammals.
Archosaur simply doesn't give mammalia a brake
Really what was it?
its between the big croc and andrewsarchus, only sparse remains of the two have been found so only time will tell
@@godemperorlech5422 Andrewsachus was actually downsized it’s not even a contender for biggest mammalian predator.
One group that I would love to see being talked about would be the terror birds. People call feathered t-rexes giant murder chickes only because they never heard about those baddies KFC in the making.
Since i know that you read and care about comments: i would be REALLY interested in the early evolution of arthropods ... i think i never heard enough information about the giant dragonfly or how even was it possible for giant arthropods to exist in the first place, how they lived
Seconded! Arthropods are freaky and I want to know more.
I agree arachnids would be pretty interesting
I believe the oxygen thing is being questioned a bit with recent discoveries of huge millipedes who are older than most giant arthropods.
@@Poliostasis yes, this basically the only information i know about them
I think he’s mentioned that at least a couple of times, and if he hasn’t, then I’ve heard this said on several other videos.
Before you dumb down these gem vids, please first go watch the less-technical videos and build your way up.
Great video. It is nice to see crocodylomorphs getting more attention. If you want to work together in the future, I am certainly up for it.
While it feels a little pedantic, there are a few minor inaccuracies in the video I would like to address.
You suggested that dinosaurs and pseudosuchians evolved their upright limbs independently of each other. However, recent papers on early dinosaur-line archosaurs like Silesaurus have found they also had the pillar-erect stance of the pseudosuchians. Since this is the condition of the first members of both branches of Archosauria, this was almost certainly the ancestral condition of the clade as opposed to the result of evolutionary convergence.
The creature at 3:51 is not a Triassic pseudosuchian. It instead depicts Razanandrongobe, an exceptionally massive Jurassic notosuchian.
Finally (and this might have just been an omission for time.), besides the planocraniids, there are also fossils of large predatory notosuchians from Cenozoic Europe (Iberosuchus and Bergisuchus) and Africa (no fossils complete enough to warrant a name). They were either a separate surviving linage of sebecids or some of their closest known relatives.
An episode in the same theme about Phorusrhacids would be truly amazing!
Those terrestrial birds are very badly represented in general and are fairly misunderstood. They usually are associated to ratites in their biology while they would have been completely different and much closer to birds of preys, carnivoran mammals and Dromaeosaurs.
All the large ones were apex predators of their respective ecosystems and hunted a large variety of animals, possibly in pair like most birds of preys, using the large sickle claws on very wide and robust feet to hang on preys, adding to this bites and peaks with their terrifying beaks.
They are typically even creepier and better JP Raptors than the JP raptors themselves! They are truly outstanding!
Um, yeah. Did he just refer to them as *TERROR Birds!* ? 😳🦚🦅
One of the larger - if not the largest iirc - actually turned out to be a herbivore.
@@apexnext yes. Phorusrhacids are the terror birds family
@@phunkracy you are referring to Gastornis which apparently isn't a Phorusrhacid afaik but it could be as one of its relative, Brontornis which was a carnivore and even larger, could be considered as one.
Largest known for sure Phorusrhacids would be animals like Titanis, Devincenzia or Kelenken.
🤯🤯🤯
I enjoy this format. Tracing a single lineage through time in a single video helps to understand where they came from. The Era videos help to understand how the world was.It's looking at information in different ways - even if much of the information will overlap.
Yes i really like these deep dives, so keep it up! There are so many groups that get skipped over and yet are very interesting. Case in point, trilobites. They lasted a massive amount of time and the amazing amount of diversity that occurred within the confines of their very simple body plain fasinates me
When I was growing up, we were given a very narrow view of animals in prehistory, probably because most of the research hadn't been done yet. Now, looking back, it is incredible to me that for most of Earth's history, this was a planet made for reptiles. It is very interesting just how many niches different "land crocodiles" managed to achieve. Barinasuchus looks like such a fascinating animal and is the newest branch of the crocodilian family that I've heard about. I'm looking forward to part two!
Was hoping you'd shot for this topic man. Indeed most of the Notosuchians and Neosuchians are incredibly underrated and unknown by the general public. And to those who don't know there are at least a handful of living crocodilians that do pursue and hunt upon land. Cuban crocs along with the dwarf crocs, and dwarf caimans have been documented to hunt their selected prey on land. Sometimes gators here in the Sunshine State occasionally hunt prey out of the water as well, once the opertunity presents itself.
Indeed, also there are a number of videos showing various crocodilians that normally hunt in the water being willing to dash short distances on land to grab prey (though they normally still start out in the water).
Alligators are inspiring lizards, born for the water, but refusing to be limited by their unfortunate legs.
Gorgonopsid / Therocephalian video would be class - saw a reconstructed Gorgonopsid skeleton in a museum and thought at first it was a buffed up smilodon but turns out they were apex proto-mammals from the Permian!
I love to get this kind of deeper info about the less well-known chapters of evolution. They are overlooked much too often despite having reigned this planet for so long. The same video about placoderms would be fascinating, too!
Yes!!! More videos like this covering a single family through the ages would be amazing!! Could you do this with some of the invasive species we see causing such problems today (e.g., Lionfish, Asian Carp, Burmese Python)?
I would not doubt that with our warming climate that another terrestrial crocodilian will evolve a few million years in the future, several species such as the Cuban crocodile, Cuvier's caiman, and even alligators are far more terrestrial than one would expect. Cuvier's Dwarf Caiman is especially interesting due to the uniquely bladed teeth, they dont have typical crocodilian teeth or behavior and are extremely interesting.
True, while the changing climate is cause for concern I can't help but imagine how some groups of animals will adapt to deal with the changes. Purely speculation, but it would certainly be interesting to see if reptiles manage to muscle in to more dominant roles.
@@seanmckelvey6618 i wouldn't doubt it, certain monitor lizards and crocodilians are already almost there, and with how most mammalian apex predators are in decline its a good time for some of them.
I'm super happy you covered this topic! "Landcrocs" and other weird types of crocodile relatives fascinate me ever since i've found out about them not too long ago, and i really enjoy your style of presentation. Keep up the good work, can't wait to see the next one 😉
Love it, but I think you could do a twenty part series on all of the suchids and protosuchids they're all fascinating.
To me it feels like the cenozoic South America was far more interesting and different from anywhere else in the world. I would like to see a video analyzing this.
agree.
Thirded.
🤚🏻
But I am endlessly excited for the full episode on Australia!!!
I’m happy with every video you’ve made-I enjoy learning more about individual’s favorites because those often aren’t what I learned about in my undergrad days.
This was an awesome surprise. Land crocs are horribly underrated and I'm glad to see a deep dive into them. Heck, I've looked them up more than once and somehow missed that they survived the Triassic, so thank you for setting me straight.
On the other hand now I'm curious about some of their South American competition. Terror birds and giant snakes seem to get just barely more attention. Any chance they could get a video at some point?
I would love that.......imagine how horrifying it would be to deal with those animals as evolving humans!
Excellent, as always. What sort of other animal group deserves this deep dive? All of them!
Oh hell ya! I can’t wait ever since your previous video talking about them. I hope you cover the turtle who hunted crocs(I think it’s a thing but I leave that to the you expert
🐢 hunt 🐊
😳
I am so obsessed with land crocs, its just so fascinating how different they are to the animals you usually think of, when you think of crocodiles. Already hyped for the next video, as far as I know Cuban Crocodiles are the most terrestrial crocodiles today, but I dont know if thats worth talking about, since you are a Paleo-Channel and I dont know if most terrestrial means much, when the whole thing of your family is being a water ambush predator, although there were Giant Sloth bones found with bitemarks which would match those of Cuban Crocs, which could suggest they can hunt at land.
I am so glad to know about Barinasuchus now. I was under the impression that land crocs went extinct after the first cooling. Neat to know there's so much to learn.
Best episode yet! I learnt more in this episode then any previous. Being an Aussie I can't wait for part 2!
Watching your history of the earth series made me realize I know almost nothing about fungi. Could you explore what is known about early fungal evolution?
One thing I love about your vids, you show where the land masses are at certain time periods, so I don't have to go look it up! Thank you!
Oh I'm early. Only 2 views. As a Floridian I am obligated to know of crocodiles.
As a Brazilian, i also have such an obligation, even though people dont really think about our, amazing brazilian crocs
But I thought only GATORS live in Florida?!?!?
@@MikeJones-yo8en There are both crocodiles and gators in Florida.
@@donovanchilton5817 Really? I had no idea!!
@@MikeJones-yo8en Yessir, American Crocodile. Southern Florida.
Great video! Terrestrial crocs don't tend to get the recognition they deserve. For one as this video shows they were supper diverse in size and niches during the Mesozoic and some persisted as a dreadful reminder of that era well into the "age of mammals". From what I've seen the idea of land crocs is kinda horror inducing in a lot of people's minds even when introduced to not too big forms like Kaprosuchus (who may not have been terrestrial but is one of the most popular ones). And then you have animals like Fasolasuchus, Razanandrongobe and Barinasuchus which would seem truly monstrous to us. I'm glad that you are consistently giving the spotlight to not so well known animals that deserve more attention and that you're doing it in what I think is interesting, fun and easy to digest way for people who are not yet very immersed in paleontology and the different terms. With that said I'm looking forward to the next part covering the Mekosuchinae. Keep it up the good work!
Dude you are on fire with these videos! Fuckin' love watching you rise. 🤘🏻 rock on
😎🤘
Fantasric video! I just watched your original croc video yesterday. Sound level is great, too!
Yeah did he raise the volume a bit? You noticed it too?
It's definitely much better in this video, I feel like. 😎👍
An idea for another episode like this would be the history of the sharks one of the most successful group of vertebrates
Man these are SO FACINATING! Why is there No documentary on all these guys! There are so many to cover. I love their diversity and styles. They are such epic creatures.
I was really hoping to hear about the aetosaurs and the other herbivorous psudosuchians of the Triassic
This was fascinating. You should cover the evolution of zebras/equines. I’m not very familiar with it, but it seems cool.
I love these deep dives. I think they would compliment the broader epoch- and era reviews very well. So, yes, I am greedy: I want both!
I have a request! I love your stuff and I hope someday you will cover gliding marsupials!!
He did do some Gliding videos some months ago. Were any of them Marsupial? Have to check and see. 😎👍
@@apexnext there was only one gliding mammal on that video, but it’s unclear whether it was marsupial or not.
Looks kind of like Simosuchus was taking the turtle niche for a bit.
Another great video! I'd love to see you make a video focused on hyaenodonts
Oh man, I can't wait for the next part of this, the Australian land crocs never really seem to get the attention I think they deserve (although being Australian, that's perhaps because of a bias on my part). I would love to see some videos on Terror birds as well, they're another group that I feel like get overshadowed.
Great video. Thank you for this. 🤗 I'm already looking forward to the second part. 🐊🦖
My wish for the next Species Focus: Terrorbirds or Penguins.
Terrorbirds for reasons 😅😎
And Penguins, yeah - cause, of their very special way of Evolution! 🐟🦎🦖🦅🐧 🤓
Seconded. 🐊🦖❤️🦅🦚🐧😁👍
i always love your videos, definitely my favorite youtube channel right now, keep up the content
I would really like to see a video chronologically showing biggest Dinosaur, Reptile, Mammal, Bird etc on Land per period of time (could separately show in water too)
Im fascinated by the biggest ones and its nice to have the context of the biggest members of another group that existed at the same time.
Hope you cover the tree-croc Mekosuchus in the next video. As far as weird croc/croc-like creatures go, in my opinion, the poposaurid Shuvosaurus takes the cake. Ostrich Croc.
Great, vid! You have quickly grown to be one of favorite creators of the platform, keep it up👍
I love your vids, keep up the amazing work!
This was a fascinating video. I have always thought that the Pseudosuchia don't get enough lime light in popular media. Thanks for this beautifully summarized video.
Your narrative teaching style is both educational and involving. Good job! I love to learn from your videos!
It's always a pleasure to see an update from you. This was fascinating, I'm excited for the next part. Thanks for all your hard work, hope you're doing well!
Commenting before watching because I know this is going to be good. Am going over to Australia in Feb (NT) and wanted to know more about these wonderful Crocs before going so thank you.
Your channel is a smash hit, thanks for both sticking to your ongoing series and in advance for following all of your series through to their inevitable conclusions.
My favorite series,I absolutely adore Land Crocodiles they're just so amazing and I hope you have a good day
This is such an interesting video, thank you again for all of your hard work and for doing such a great job making this all so fascinating!
I think I am echoing other people here when I say I would love to learn more about the Terror birds and the rise of the arthropods.
Also, one of my very favorite critters I learned about from Dinosaur Revolution and it was called Beelzebufo. Would you be interested in talking about the rise of giant amphibians and giant frogs and toads?
Here's another idea that you talked about briefly in another video but I would love to learn more: fungal forests! Let's talk about giant mushrooms and their evolution.
Thank you again for your very excellent videos! I look forward to the next one!
This was awesome! Can't wait for the next video 👍
Loving these “history of” videos. I’m still learning so much about all the lineages of animals and plants and the variety and awesomeness they all contain!
As some one else mentioned I would really LOVE to see a video covering the history of arthropods. Specifically I’m interested in their transition from sea to land but honestly anything you could say about them would be appreciated!
Great contents as usual... An idea though (for further contents) - how about an history of the Testudines (aka turtles, terrapins and consorts) clade ?
Ah ah reading through the comments it seems a bunch of people already have plenty of ideas for you and Tim Tim to cover !
It's a great pleasure to watch your very compelling videos about the creatures and the world that we can never visit another way. You have a wonderful skill for making it all come alive in our imaginations.
Enjoyed your presentation. Liked the end music on this one particularly.
Thank you for your work on this subject.
suuuuch a good channel. real gem, and incredible you don't have more subs. really enjoy your channel, please keep it up!
New subscriber here and ib like to say I am enjoying the evaluation of the creator
So glad to see a new video! It's always nice to do a deep dive from time to time.
Fantastic video! I'd like to see more cenozoic snakes be covered.
My son finished school and then saw you uploaded and immediately watched this video for fun!
That's a sign that we are both doing a good job!
Dude you gotta get a discord going I’d give you so many ideas
Early bird evolution would be a good vid
The Patreon is new, which is good.
He does have an Instagram. Which I am not a part of tho.
I also eagerly await a Discord. 😎👍
Hopefully someone in his inner circle is Discord savvy.
One of my favorite groups of animals! I'm planning on doing a comic involving the Cretaceoua fauna from the Bauru Group in Brazil - my country -, including some notable Notosuchians ^^
Thanks for the video as always friend !
I love this format! Definitely would love to see more of it in the future - it really helps to understand how different types of animals evolved and why. Thanks for your making these videos!
Amazing video! It's just what I needed :D. Keep it going!
Great video in both content and format. I love the land crocs and your style is really well suited to giving these fascinating and underappreciated animals some time in the spotlight.
Great vid, can't wait for part two
I love these videos and cant wait for the history of the world triassic period! So many different species of the crocodile family! Your videos are interesting, and educational, and with a touch of humor and light heartedness. So good. I love them!
Yes, another Paleo Analysis video. Your videos make me so happy! :)
Loved it, definitely keep doing the deep dives!
I truly love all your videos thank you for this gem ❤
I'm happy to see this niche explored
Nice timing, i was wondering through the bush the other day and thinking it was tops that Quinkana ain't around any more.
Commenting just for positive things! I like your presentation style, your evolutions, and your voice is a match for my favorite biology teacher to boot! I hope you don't get bad comments, and if you do, I hope there's 50 good ones to thank you right after!
I love you videos! I’ve always been interested in terror birds of South America, and other sort of similar monstrous birds. It would be cool to see you do a video on the lineage of those beaked badasses!
It's amazing how close we were to meeting the last tall crocs compared to things like non-avian dinosaurs but at the same time sad that they are no longer with us today.
really enjoyed this...looking forward to the next episode!
I very much like this format. Good work.
Thanks for the awesome content and great video!!!
This was a great video! I've been following your work for a while now and it just keeps getting better! I've never heard of many of these species and groups, and I'm a Paleo nerd 😂 I'd like to see the terror birds and early mammalians too, maybe the feared "cats vs dogs" type with the archaic hunters of North America since we had some crazy cenozoic beasts. Keep up the great work!
At some point, maybe as you get closer to the Holocene, I'd like to see a video on those colossal land mammals
I like this format keep at it!
Hi thanks for this video. I enjoyed it! During a recent road trip from Boston to Chicago I couldn't help thinking of glaciers and the inland sea seeing the terrain change as we went further west. I'd love a video on the inland sea. Or the forming of the great lakes. FYI the Field Museum was wonderful!
Terrific video! Can’t wait for Part 2!
This was a really well put together video.
1:23 I know that this question is slightly off-topic, but may I ask where the footage of these beautiful woods were filmed, if you know the answer? It reminds me so much of where I grew up in Pennsylvania, at the extreme north of the Appalachians. Thank you for always making such interesting content!
I may butcher the spelling but I'd like to know more about the Tuatara. I recently watched something about them and I'm very intrigued. I'd love to hear more about these impressive animals.
Cool! This was one of your best lectures!
Awesome coverage of the land crocs, about time they started to receive more attention. Its quite bizarre there hasn't been any documentary's on land crocs in the Cenozoic, would be pretty cool to see a documentary focusing on land crocs in South America and Australia. Im also hoping they find more post cranial material of sebecids and complete skulls as well. Would like to see studies on the bite forces and speeds that sebecids would be capable of employing as new material is uncovered about these incredible terrestrial crocodylians. I wonder if sebecids could have lasted longer in South America perhaps to the Pliocene, maybe even the Pleistocene which sounds unlikely, but would be cool if so, im kinda reaching, but if they did make it to the pliocene, even Pleistocene it would probably be a very small species I would imagine.
i love 99%of your videos the 1% is the ones that are rlly old and dint watch keep it up your really good i love your content
Your videos are great! Thank you!
Love your voice another great video, can’t wait for next one!
this was a nice video to listen to while I was putting my roof on, but I'll have to listen to this again because I didn't retain a thing. still like your video on placoderms, they're my favorite critter also looking forward to when you do the mimus's.
Are we doing Desert Crocodiles next..?? Really enjoyed this.. and for the deep dive idea and how it all connects. Thank you.
All I saw was "history of", and I got excited thinking it was Carboniferous time
I really enjoyed this video. I would love to see one about birds! As birds are sometimes called the avian-dinosaurs and I would want to know when did the split bitween non-avian and avian dinos appeard. It would be a fun video as birds are found all throughout our planet!
I really enjoyed this, thank you!
If you're taking suggestions, then I've got one that's not often thought about: I'd like to see a video exploring the mammals of the Cenozoic... that didn't make it.
I'm not talking about hot topic, big-shot extinct mammals like mammoths, mastodons, smilodons, or even Thylacoleo.
I'm talking about mammals which are completely unrepresented in the modern day, mammals that were outcompeted, and mammals whose niches haven't even been refilled since their extinction.
I'd love to hear about stuff like: Macrauchenia and the other Notoungulates; Paraceratherium, and other bizarre Perissodactyls; Mesonychids; carnivorous Artiodactyls like the Entelodonts and Andrewsarchus; and Creodonts & Hyaenodonts!
