Qianosuchus: The Triassic Terror of Both Land and Sea
Вставка
- Опубліковано 5 лип 2024
- Qianosuchus was a medium sized reptile who lived in what is now China during the Middle Triassic. Although only distantly related to crocodilians, this carnivorous pseudosuchian took to the water independently of them. Notably, Qianosuchus possessed a tail even better suited for swimming than those of crocodilians yet was also much more comfortable (and deadly) than them when on land.

The new narrator is great and all but there is something comfy about hearing our boi Chimera's voice again
Agreed
Exactly
Qianosuchus be like: "YOU CAN RUN, BUT YOU CAN'T HIDE!"
Quianosuchus sounds like a real life titanosaurus/godzilla! Also love to hear your voice again, its my fav.
Qianosuchus probably have had the most well shaped body for a life in a world of islands
I find it kinda funny that animals that came before dinosaurs can be referred to as dinosaur mimics. Convergent evolution is probably the most interesting thing about life on this planet. The same body plan and lifestyle has cropped up so many times that I feel like everything is something else's mimic in some way.
It was maybe an island hopper, using the ressources of islands that wouldn't support a population of them full time. So it used it's aquatic adaptions to get to a a new island once the ressources of the one they were on were diminishing. Like polar bears who can swim long distances to get from one ice float to another.
Yeah I was reminded of polar bears while listening to this as well. Makes sense given the environment it was apparently living in and explains the sort of "jack of all trades but master of none" set of features it has.
thats what he said in the video
I actually did consider adding a line about island hopping (which seems likely) along with the possibility that it was merely hunting aquatic prey from the shore, as implied by some of the art. Givens how some of its aquatic adaptions, like the tail, are better than those of crocodiles, it would have concluded that Qianosuchus was indeed a "part-time" underwater pursuit predator.
@@chimerasuchus Yeah. I guess in an island environment you have an advantage if you can exploit different types of ressources and if you are very mobile. Apart from the saltwater crocodiles, the other modern crocs are not long distance endurance swimmers, so this thing having a better swimming tail than modern crocs makes sense. On the other hand, if you want to hunt on land, you have to have those longer legs, the shorter legs of modern crocs only make sense in something hunting exclusively under water.
At it's size it probably didn't have much competition from larger predators on those small islands, but it had to be fast and nimble because of larger, specialized predators in the ocean.
comodo dragon well known to travel between islands too
so qianosucus was basically a sea lion that hunted in the sea and could occasionally come to islands and become the largest predator there ?
i think this is the closest guess ...
it probably could manage that due to the uncompetitive oceans afther the mass extinction ...
it would be intresting to see a sea lion seeded world develop such predators ...
The major difference is that Qianosuchus was far more competent on land than a sea lion or most other semi-aquatic animals.
@@chimerasuchus ye , i'd guess so , still it was pretty unique ecologically ,
More like monitor lizard lifestyle
Similar to a polar bear.
Heyyy, the old voice is back! Awesome
Please keep narrating yourself, it’s authentic!
Agree 100%
Oh, a sclerotic ring. Seeing those things always rams home that they are related to birds
Great job as always, i love learning about more obscure prehistoric creatures because I'm sure they always end up being far too interesting to forget about,keep up the amazing work!
Perhaps do a video on Parahelicoprion next? It's a very obscure genus for it's estimated size (at least for the larger species).
Good to hear your voice again
I hope you do a video on Sillosuchus!
Love watching your vids!
Well done as always. You're getting an A!
This narrator is so good. Very distinct voice and a very easy to follow script makes is easy to understand and recall the information.
Could you possibly do a video covering Fasolasuchus Tenax? I'm amazed that seemingly the biggest non-theropod land predator ever is so hard to find good info on
As always, thank you so much for creating & sharing these - and a particularly interesting one today (off course that's what I always think 🙂)!
You're welcome.
Crazy, normally I'd talk about the scientific angle of things, but I had a dream with these creatures in it months ago & they looked exactly like Qianosuchus. It's bizarre what the subconscious can conjure up.
Finally got caught up on the videos on this channel, I find myself watching it intently and don't want any distractions. It's always good to learn something new. Easily one of my favorites.
Awesome video as always. It's nice to see obscure creatures getting mentioned
I always thought Gauthier made a mistake having the clad named Psuedosuchia (false crocodile) should have been called Suchiamorpha (crocodile forms) as they contain Suchians. Likewise, Parasuchians, Paracrocodylomorpha (alongside crocodiles, alongside crocodile forms) is also a terrible name as they also contain Crocodilia.
"Pseudosuchia" always sounded somewhat off to me too.
Yeah. Although I like the sound of "Psuedosuchia", it and the other names would have made sense for clades that are sister groups of those containing crocodilians, like the Notosuchia and Rauisuchidae.
Or suchiosuchus
I appreciate your videos because they deliver in-depth information, yet they are at the same time concise. Perfect format to appreciate fully on the go and then jump to the next. Great paleontology short documenataries. keep it up!!!
im glad the old narrator is back
Awesome, thanks for sharing this with us.
Another great video 😎
Keep making great videos!!!
Awesome pseudosuchian from the same place as chilli crisp, the best condiment ever
Love hearing your voice!
Great video! Another interesting animal.👍
The polar bear of the Triassic. Just replace polar with tropical & bear with reptile & bingo. You have a similar niche animal.
Awesome 👏
I like your voice better than the polished voice over guy. Keep up the good work
Awesome video truly just some awesome species of prehistoric crocodilian
great video
Obrigado por colocar legendas.😚😚😚
Our host considers the Qianosuchus to be an oddity but it's funny how Kaprosuchus later came to fulfill a similar role.
I like your videos on psuedosuchians.
kind of reminds me of proterosuchus a little
Good stuff
this voice is so good
Great to hear you again. Better than the voice actor by a long way.
Wow. I like this topic
Nice 👍
It's funny how the mammalian brain will ascribe characteristics too an animal based on the shape of its face
From what I know about paleogeology, Southwest China at that time was probably a shallow marine environment, hence the reason why such amphibious predator existed, and also the reason why extensive karst formations exist in the region.
interesting video. this is an interesting animal
Why don’t you think of a suggestion making a UA-cam Videos all about Geosaurus (A Marine Crocodile and/or A Sea Crocodile) on the next weekend and/or the the next weekday coming up next?!👍👍👍👍👍⭐️⭐️⭐️⭐️⭐️
Thumbnail picuture of it looks badass
Triassic: the age of Crocs.
Can you do Twatosuchus
Do one highlighting pervatasaurus please
Have you ever tried a Vic inhaler?
When are you gonna finely gonna do one about Purussaurus ?
It might be good he's waiting. I think a paper came out this year that challenged the old size estimates and significantly downgraded the max possible size of that beast. It still would have been huge - bigger than anything alive today, but not a contender for largest ever anymore. That is, if the new paper holds up over time.
All that to say, the silver lining of waiting is we'll likely get more up-to-date science reported.
Looks like a croco-ferret
You said synomynous. Not that I could pronounce half the other hard words in your videos
You mention 7m Nothosaurs, which ones are those?
The species in question is Nothosaurus zhangi. Nothosaurus giganteus was about the same size.
So it's basically a Crocodilian with the body of a Monitor Lizard. No wonder it was so successful.
Did you say synomynous?
It's like a wingless toothless 🐉🐲
It's the same niche as a tropical polar bear would be
Why does your voice keeps changing? in your Concavenator video, your voice sounds slightly deeper.
That video was narrated by someone else, Michael T Downey.
@@chimerasuchus I prefer your own narration much more.
Don't know why, but I really prefer hearing you narrate as opposed to the other guy
The Crocodile family was diversed.🐊🐊🐊🐊🐊🐊🐊🐊
Symonymous?
6:22 looking like a whole SpongeBob character
the archosaurian jaguar
So we can all agree that everyone here basically love crocodilians 😂
😀
6:22 - What the hell is that thing?! Kill it!
Kill it!
Don't let it suffer by letting it live! Put it out of its misery!
How does a creature with a brain the size of a walnut know it has to “evolve?
It doesn't because evolution doesn't work like that. Mutations to DNA occur naturally in every single organisms. Most of these mutations do nothing (since a large amount of the genome does not code for anything and many changes do not actually affect the function of the resulting protein), some hurt the survival chances of the animal, and a few help it. These positive mutations mean it is more likely to survive and reproduce than its peers.
Over time, some of these positive mutations spread to the entire population. This can also happen with neutral mutations, which is called genetic drift, although this is dependent on chance instead of natural selection. Eventually the population has changed enough that it can no longer be considered the same species as before.
Additionally, when two populations of the same species are geographically isolated from each other long enough, their DNA can diverge to the point that they can no longer interbreed. One this happens they are now considered two different species.
Well, a creature with the brain the size of a walnut can make a youtube channel and comment. Don't underestimate the walnut brain.
@@chimerasuchus evolution doesn’t work that way because evolution doesn’t work.
I hope you come back and narrate your own videos again cause it’s just not the same :/
Synonymous.. not synomynous 🤣
The narration is a bit jarring if I'm being honest
This dude uses too much nostril in his voice. Need the old narrator back.
