Ziphosuchia: The Blade Crocodiles
Вставка
- Опубліковано 3 жов 2024
- During the Cretaceous, Notosuchians continued their radiation on the southern continents. We’ve already examined the dog-like basal members of this lineage in a previous video, and today I’ll be focusing on the more derived and extensive Ziphosuchia clade. Meaning blade crocodiles, referring to the thin slashing teeth of the carnivorous members of this group, in reality Ziphosuchians were highly diverse and also included herbivorous and omnivorous forms as well. Some genera were truly bizarre, with complex tooth structures at times very similar to those of mammals. The derived Sebecosuchians survived the K-PG extinction event in South America, remaining large predators that managed to successfully prey on the continent's endemic ungulates.

I’m so sorry about the final three minutes of this video being left in. I forgot to cut off the music track so this extended the video.
Ah dont sweat it, it was the most relaxing mistake ever made :D
Thanks, glad you didn’t mind!
Don’t worry about it, I never thought an outro could be this soothing
bro gave us time to reflect
To me it's kind of fascinating that there were predatory land crocs ruling a whole continent for millions of years during the cenozoic
And some of them evolve similar to dinosaurs
I said this once and I'll say it again, the next prehistoric documentary really needs to take place in Cenozoic South Amarica.
@@gattycroc8073 agreed

Especially during the Miocene.
The stuff that evolved during that time was absolutely nuts.
@@beastmaster0934 The Middle Miocene was the last hurrah of the South American predator lineages, before environmental changes in the Late Miocene caused their permanent decline (and the extinction of the last sebecosuchians), culminating in the South American predator guild collapsing around 3MYA in the Early Pliocene (prior to the arrival of predatory placental mammals from North America in the Late Pliocene).
The croc morphs were truly a diverse and experimental bunch.
The more fossils found seems to show that wherever possible they were giving the dinosaurs a run for their money.
The music at the end was good too.
Great video? Crocodylomorphs are awesome, it's a shame they're usually overshadowed by dinosaurs. I think it's especially cool how much they converged in the past where you could sometimes barely tell them apart from early dinosaurs
I know right, crocodylomorphs are amazing.
Seems as though these land crocs picked up where their rauisuchian cousins left off.
Exactly, almost like the Triassic never ended!
Sounds like Mother Nature was testing out some ideas on these crocodile relatives!
She certainly was, something that kept happening in the Pseudosuchian lineage. The Crocodilians around today are such a tiny fraction of the diversity that once existed.
@@dr.polaris6423 It could be that they are just biding their time. If they can outlive our species, then they will be well placed to take over... but first, they've got to survive our depredations. I hope they do. They managed to outlive the dinosaurs, they could outlive us mammals. Good luck to them!
So interesting how diverse the crocodile's were back then. Same with the lemurs, marsupials and flightless birds.
Interesting how both armadillosuchus and armadillos convergently evolved in South America
Nice! I can't wait for you to make a video about the Beast of Bray Road. It would be fun to see you examining this cryptid. :)
I'd wished that they would have gotten you Dr.Polaris to work on the Jurassic park movies maybe they would have been way awesome.
@Dr. Polaris ,
Wow, convergent evolution and divergence city! Adaptive radiation into everything. Fascinating and enjoyable. Why was there three minutes of light music at the end?
Sorry about the ending, that was an editing mistake in my part.
Makes me wonder about the diversity of crocodiles millions of years from now
All dead...
it’s likely they won’t speculate in the near future, with their primary changes happening rarely and in the absence of competition. could absolutely see a croc becoming terrestrial though
Non-existent. They would be extinct.
@@juanjoyaborja.3054 didn't I already say that?
@@thelostronin I didn't see your reply, sorry. I guess we converged on the same idea.
The title was enough to get me here. Very succinct and intriguing.
The Simosuchus is adorable and harmless, unlike carnivorous crocodilians. I want one as a pet! :D
the way it yawns is shooo cuteeeee awwwwwe with its chubby cheeks and pudgy body and cute lil eyes squinting
Fantastic video! Also, can’t wait until your next Speculative Evolution video!
The blade crocodiles sure are some cool dudes also this video is amazing
I know right, maybe one day we will see them in a movie
Wow. I never knew crocodiles had such a diverse history. The thought of grazing plant eating crocs is surreal to me. Like seeing a spider munching on grass instead of other bugs.
This video was so great and that's pretty good
Was it “so great” or “pretty good” I’m confused
Hope you've been doing well; and thanks for another excellent video.
Also, hello from Alaska!
Blade Crocodile is just a ridiculously awesome name for a beast.
For me, the Cretaceous remains the most underrated geological period. So much unique but less talked animals beyond the dinos.
I have a similar interest in non-mammal Cenozoic creatures.
You do a good job digging up obscure lineages
0:54/0:58 As detailed by CHimerasuchus on one of his videos.
awesome video, crocodylomorph are a very interesting and underrated group reptiles.
I also really want to see a video on the sebecids.
I think they're overrated among the obscure paleontology crowd.
@@SliceySlicer I don’t think so. I haven’t seen many conversations about ancient crocodylomorphs, as compared to ancient ungulates, big cats, dinosaurs, sharks, etc.
You know if they were a living species today that Simosuchus would absolutely be pampered pets living the good lives with our kitties and puppies. 🥰
Crocodylomorphs are more diverse than we think
Yep, and this was the case in some areas until the Pleistocene.
@@dr.polaris6423 One land croc, Mekosuchus, made it well into the Holocene. One fossil is only 3,000 years old.
I know if some of the smaller species were still alive, they would be extremely popular in the exotic pet trade.
Freshwater crocodiles are already super popular as pets in Australia. These other crocodylomorphs would be very popular too.
@@juanjoyaborja.3054 ...as are caymans in Germany. Well, as long as they are wee. Then they tend to get abandoned. I vividly remember the cayman in our local bathing pond, and how the pond was off-limits for most of a summer. And the raccoons in Madrid. And the parrots of Barcelona. And the American tortoises displacing our native Spanish species.
Somehow, I'm not a fan of exotic pets, or the exotic pet trade.
@@joschafinger126 The main problem with exotic pets is how they can become invasive species. Luckily, freshwater crocodiles are native to Australia, so aren't a huge issue. And they're kept as pets for life, simply because they don't get longer than 5 feet and weight about as much as a decently large dog.
@@juanjoyaborja.3054 Good point. I wouldn't mind having a tame squirrel myself ('exotic' enough though native to Spain, if regrettably rare in my part of it), but I guess one of those might not be compatible with a ratcatcher dog and two cats. Would keep in shape, though 😉
@@joschafinger126 I see. I personally want a long-lived invertebrate as a pet, such as a horseshoe crab or a large lobster. Those are usually pretty easy to care for, apart from keeping a huge tank.
🤯 these are really interesting and amazing.
It looks like crocodilians have evolved backwards!
Dr Polaris
I want to know what the intro logo (midnight sun production) is
Is it your own studio? Your sponsor? What is it?
11:13 onwards is the section of the video exploring the ecological niche of Ziposuchia in the modern day
Hi...
Love your content...
But.....
Could you do a video all about the various fancy words you use to categorise everything ?
😅 its like your speaking Latin..
( yh I get most of the terms probably are Latin) 😅
I don't generally look at early crocodilians as potential house pets, but I think Jurassic Park could make a movie based around the restoration of Simosuchus as a house pet. Hard to fit the adjective cute to anything from the Crocodiles but still I wouldn't mind having a couple of those in the backyard.... Also if the theory that Crocodilians are a offshoot of an endothermic ancestor these small crocs would make a lot of sense. Putting them into a wild pig type niche appeals.
would be so cute if Simosuchus made pig like snorts
That title... Vampire Crocodiles.
8:36 The namesake of a paleotuber's UA-cam channel.
who Dr. Polaris should collaborate with.
What's with the 3 minutes of nothing at the end?
WoW 🤩 ..
this made my day and afternoon 🧠 🧠❣️❣️
The trailers for the Jurassic park/world movie Dominion has started the movie is supposed to be released this summer I'm ready for 🤯🤯 and the critics.
1:32 Baby-Godzillas
this is gonna be completely random but is the back ground music you're using from world of warcraft? bc it sounds like music specifically from Sholazar Basin.
what is the music used for this video?
Actually they mean sword tooth not blade tooth. So is the evolution of mammalian dentition inevitable.
If the whole line of synapsids went extinct, would some reptile develop this type of dentition? Also, where those crocodilian forms competitors to mammals?
Dat intro music though
way is ther a balck screm from 11 minuts to the end
Sweet! 3 bonus minutes of pure blackness at the end!
... only joking. Awesome video, and the editing error starting from 11:13 shouldn't be hard to trim out. 👍
TIL theres more than ONE galloping crocodile
Why do you call yourself Dr. Polaris?
They look like evolution's experiments to come up with the eventual monitor lizard design.
.
Notosuchians, the ultimate waste bucket😂😂😂😂
I thing you are inventing crocs for clics
Nope
can you do a video on desmostylians
Maybe it was that I was listening to this video in the background, but at 1:53 I was so sure that I heard "Paleontologist Burnt Scrotum" that I had to rewind it to confirm that *couldn't* have been what was said...... 🤣🤣🤣
