Borealosuchus: The Crocodilian That Outlived The Dinosaurs
ฝัง

- Borealosuchus was a survivor of the catastrophic mass extinction at the end of the Cretaceous Period. A prehistoric crocodilian (or a close relative of the crocodilians), it lived twenty million years during the Age of Dinosaurs and lived another twenty million years during the Age of Mammals. Although Borealosuchus started out small, it become a top predator in the new Cenozoic world. It is also one of the most important prehistoric reptiles in understanding the early evolution of Crocodilia, and may be close to what the last common ancestor the of today's crocodilians looked like.
Thank you to the themattalorian for narrating this video.

Dinosaurs: *died out completely*
Borealosuchus: *"Bye! Have a great time!"*
Technically one group of dinosaurs, the birds, did survive.
@@chimerasuchus Borealosuchus: "Suckers!"
Birds: *"UNO REVERSE CARD!"*
@@TheAnimalKingdom-tq3sz meanwhile mammals be off in the corner playing Texas Hold'em with a Royal Flush
Birds: excuse me?
Its only a matter of time before we get land crocodiles again, it always happens, the Cuban crocodiles is already close. Funny the largest land predator during the so-called age of mammals was a big land crocodilian. barinasuchus is my guy and just another reason I should never get a time machine.
I am interested what gave this crocodilian edge over its extinct brethren in surviving Cretaceous mass extinction.
Most likely its smaller size
And being cold blooded. Cold blooded animals don't need to eat as much as the warm blooded dinosaurs.
There are videos presenting evidence that crocodilians had developed endothermy(warm bloodedness), but that some had reverted to poikilothermy(cold bloodedness). This would allow them to survive food scarcity that would end their higher energy cousins.
Living mostly in water probably shielded it from the worst and it fed off the survivors as they came to drink....and Crocs today will eat dead animals, even prefer rotting carcasses to fresh as it's easier to get pieces you can swallow since you can't chew. They have stomach acids that can handle dead flesh that would kill all other meat eaters bc of bacterial infection....
Very interesting! Alligator fossils have been found at the Gray Fossil Site in Tennessee that are about 5 million years old. I understand it is a new species and possibly an ancestor to the American alligator.
Well they say that turtles and tortoises just march on through over extinction boundries. Something that can live on crushng their shells open and gobbling them down is going to go pretty well.
-Outlived the dinosaurs.
-Avis are laughing at you right now for thinking that.
Wow, another genus/species I've never heard of and further more, one of the few that survived the Kpg extinction. Any paleo channel will tell you mammals no larger than a small dog, turtles, snakes and crocodilomorphs survived, but none ever describe examples.
There's survivors, and then there's crocodilians. They're on a level.
Only because he hid in water and had ample supply of Dino to eat because they were struggling.
Another excellent, well researched, and interesting video with good images and clean, clear and pleasant narration. What more can you ask for?
Good video. This is one of the common crocodilian fossils in North Dakota, where I graduated college and will return to soon.
Instead of the newer species becoming piscovores I'd suggest they were maybe not eating so many turtles!
The mesozoic species inhabited alongside larger more piscovorous and generalist cousins, so I think it had that alligator snout so it would be more efficent against armoured prey.
Indeed the world in it's cooling phase during the later cenozoic has put a significant barrier upon crocodilian range and diversity. Should crocs survive us and live to see a more welcoming climate I do believe they will become more diverse and perhaps reclaim lost niches.
Alligators are already expanding their range northward due to global warming. In recent years they have been seen in Tennessee.
@@jacobdalland1390I wonder if the American Crocodile will do the same tbh.
In a world filled with smaller land animals you'll want a slender mouth to catch your prey when you yourself are a giant among them. Pretty simple to understand. You don't use a bear trap to catch a mouse.
Congrads on getting a narrator. Now we can follow your excellent research. Go back, if you can, and re-record your favorite videos. I finally subscribed.
I find the narrator to be bit distracting. I was confused that had I even subscribed to this channel with the first video of the narrator that I watched but the content was good and went to check the older videos to find out what this channel was. I have horrid namy memory so couldn't recognize by name.
Imagine surviving the most iconic (not the most devastating) mass extinction of all time and then getting KO’d by good ol’ global climate change. It really says something about the nature of extinctions.
Nice vídeo! I want to see a video about the Dyrosaurs, because almost no one talks about them.
Really cool to see Alabama fossils get more recognition.
Finally, a no nonsense channel about prehistoric life, free from dumb list videos and annoying face cam talks.
It's funny but also not funny at the same time because the Borealosuchus survived one of the greatest mass extinctions ever only to perished because of the climate change. In other words, the biggest gun is not always the best gun.
YET AGAIN ANOTHER AMAZING VIDEO AS ALWAYS!
Great as always, thanks for sharing with us Boss.
The terror birds would like a word with you.
Another great video 😎
Keep up the good work! Mever thought i see a -suchus channel. Gud shiit
narration good. better than robot voice. I enjoy your vids.
one of the few creatures that existed during the dinosaurs and did not change much. Evolution seems to have stopped for them. We do not take into account the inhabitants of the seas and oceans)
Like the narrator even though going backwards I got used to your voice
Great video!
Thank you!
Is Borealosuchus a true crocodilian or atleast, a crocodylomorphs? And is there any other true crocodilian and crocodylomorphs that is contemporary with the Borealosuchus?
the genus belongs to the clade crocodyliformes, so that would definitely at least make them a part of crocodylomorphs
Borealosuchus is usually found to either be a true crocodilian or the crocodylomorph mostly closely related to the crocodilians. It coexisted with a variety of crocodylomorphs, especially true crocodilians, over its forty million years range. Examples include the Campanian Deinosuchus (4:40) and in Hell Creek Brachychampsa and Thoracosaurus (0:58). All three except maybe Thoracosaurus were true crocodilians.
@@chimerasuchus wow, never thought the genus Borealosuchus lasted that long
I think you are either mixing up the -morphs and the -formesor the extinction events. Only the crocodylomorphs survived the End-Triassic extinction 200 million years ago, so of course Borealosuchus is a crocodylomorph. Only the crcodyliformes survived the K-Pg extinction 66 million years ago, so Borealosuchus is also a crocodyliform.
The Wikipedia page hasn't been updated to include the Alabama fossils, which extended its range significantly. Still, although it is rare for even crocodylomorph genera to last so long, the genus Alligator has been around for 37 million years and the last common ancestor of the American and Chinese alligators lived 33 million years ago. Both Borealosuchus and Alligator were outdone by the exceptional crocodylomorph genus Araripesuchus, who lasted about 60 million years.
I do enjoy these videos about these crocodiles subspecies.
Are you going to think of a suggestion making a TH-cam Videos all about Geosaurus (A Marine Crocodile and/or A Sea Crocodile) on the Next Chimerasuchus Next Saturday coming up next?!👍👍👍👍👍⭐️⭐️⭐️⭐️⭐️
The artwork in this episode is awesome 👌 🐊
You know... animals like this, along with the species that we don't know existed yet has me convinced that some species of nonavian dinosaur did survive the KT extinction event, and then went on to go extinct later on.
I remember reading about some theories that speculated that at least some non-avian dinosaurs lasted up to 500.000 years after the asteroid hit.
@An Actual Rat I made a speculative evolution version of the Emela-Ntouka on my channel, I still gotta finish painting it, but the idea is that it's a ceratopsid that survived the KT mass extinction event because it's ancestors were small, omnivorous, and semi aquatic, were it eventually evolved into a large, trunked animal.
Borealosuchus is such a cool animal, glad you did this amazing video on it
Really cool,and hope you have a great day
That's interesting
👍🏻👍🏻👍🏻
nice
champsosurus also outlived the dinosaurs.
who wants to see a documentary where a Borealosuchus takes down a Titanodies like how modern crocodiles hunt water buffalo.
❤❤❤
dinosaurs are still alive tho.
Technically yes. I just couldn't think of a better title.
@@chimerasuchus why not put evolution in reverse on crocodiles, as well as birds that way prehistoric species could just evolve back into existence
Only the fittest survive.
north crocodile eh?
Lollll
Cannibalism is an possible cause
First yay
Can i get pinned
For being first?
For the algorithm gods
Ahhhhh the non gay channel
Dinosaurs, Pterosaurs, and Marine reptiles: *go extinct completely*
Borealosuchus: *_“OH, NO ---- ANYWAY !!!”_*
