Same, I started listening to this channel a couple years ago during a time where I was having major health complications, and it would literally soothe my pain and help me breathe. The brief intro to this channel instantly calms my nerves to this day.
@themug406 you don't know what's going on in this dudes life, maybe things are more chaotic for him than they are for you. Maybe his car just got totaled and his workplace got burned down. You probably just hear 'chaotic times' and think he's talking about covid or something.
This thought just hit me: Imagine how this animal went extinct so long ago, and for all that time nothing thought about it, or even knew it existed. It was as if it hadn't existed. And now, hundreds of millions of years later, a creature is somehow able to perceive them.
I had the thought. The amount of fossils we've found is incredible, but there's still more to find. And of those to find, how many of them are unobtainable? How many have been reabsorbed to the mantel and lost forever? How many have been destroyed by an earthquake? Now taking that unknown number and multiply it by possibly billions... that's how many different species of fauna and flora have inhabited this earth. It's crazy to even wrap your head around it all. And sad part is we will never know it all because some potential knowledge and evidence is lost forever.
But that's the thing, it's hard to say for sure how big of an impact Anomalocaris had on the evolution of other animals, including our pre-fish ancestors. Perhaps the presense of an apex predator pressured them to become faster swimmers, which was eventually one of the factors allowing vertebrates to dominate over arthropods (and other invertebrate groups).
I love these early life videos. There is something particularly fascinating about them, and wondering what their world would have been like, and how complex life might have been.
Defense mechanisms usually develop because an animal gets hunted and it doesn't make them invulnerable, just more likely to survive. Turtles and armadillos still get hunted by other animals after all.
It should be noted that the anomalocarid lineage actually made it to the early Devonian, which is seen in the late surviving member of the group Schinderhannes Bartelsi. Even more insane is the fact that this animal is part of Hurdiidae, a lineage from the Late Cambrian, which means that there is a very long ghost lineage leading back to the Cambrian from the Devonian.
The Royal Ontario Museum has a wonderful display with this and other Cambrian lifeforms. It also has with it a genuine fossil of the oldest life on Earth, a relatively recent discovery from well into the Boring Billion. So cool to see it made real like that!
this is fascinating. weirdly enough hearing about these animals that are once lived on earth makes me appreciate the cool animals that we're able to coexist with now
Perhaps we have different peaks... Mankind has turned earth into the hottest and coldest place measured in the universe. We're on the verge of manufacturing the power of stars. We have ascended beyond predator and prey to create our own future through total manipulation of everything around us. Watching this video alone is probably backed by more than 1,000 patents/inventions. I see us humans as riding the peak of evolution. To the point we dabble in it ourselves. Dogs, chickens, horses, pigs, cats, etc. Have all been modified by humans using evolution to provide superior traits and benefits to us. What did this worm thing do? Eat stuff, wow. If it was tasty enough and lived today, it might be a threatened species demanding high prices @ sushi restaraunts like blue fin tuna is.
I've for a long time found Anomalocaris fascinating because how little it resembles any currently extant animal lineage, same story as with Tullimonstrum, so I am quite grateful for this video. Interesting to learn how weird Cambrian deep sea life got in general compared to modern day animals.
I love these paleontology videos. Especially the Cambrian period and the other periods in the paleozoic era are fascinating to me. Haikouichthys, Cameroceras, Pterygotus, Dunkleosteus, Hynerpeton, Arthropleura... So many interesting animals!
Anomalocaris is my favorite prehistoric animal. I sometimes wonder, if they discover multicellular fauna in the ocean underneath Europa's ice, might it look something like Anomalocaris?
@@tiberiusdawn2042 The pressure at the bottom of Europa's ocean is thought to be equivalent to that of a theoretical 13-26km-deep ocean on Earth. The deepest point in the Pacific is about 11km down, so perhaps not really that much of a difference between the two. Something like Anomalocaris could surely survive higher up, closer to the ice.
@@noahdavis7570 Or Leonardo DiCaprio half way down to the Titanic after Kate Winslet wouldn't pull him on board her raft? Seriously, the pressure at the bottom of Europa's ocean is probably greater than the deepest point in the Pacific, but higher up the pressures are roughly comparable.
here's a fun fact,schinderhannes bartelsi,was a devonian radiodont,so the radiodonts (And possibly dinocaridida as a whole) actually may have survived for a lot longer than previously thought and we just rarely get to find them in younger rock formations due to preservation bias
@@themug406 other than capitalization and spacing(which you really shouldn't be expecting in a youtube comment to begin with), the only mistake is the comma after Schinderhannes bartelsi
@@themug406no, that’s a perfectly fine sentence right there. The real issue might be your environment as it seems that you are unaccustomed to interacting with someone so busting-full of ideas and enthusiasm. A shame, really.
I imagine it depends on exact anomalocarid species. Those that ate plankton or free-swimming prey probably tasted pretty shrimp-like, but those that hunted on the seafloor might've tasted more muddy or sandy. But this is just speculation-it's sad we'll never really know. :(
Love it! Anomalocaris is one of my favourite prehistoric organisms ever since I first saw it in BBC's walking with monsters documentary back in the day 😁
when imagining these animals moving, i think we should remember that the cambrian was literally the first time complex bodies with muscles controlled by nerves and brains had existed. anomalocaris would probably move very slowly and clumsily compared to the dynamism of predators today, but since their prey were in the same boat, it would have still been an effective hunter for the day
@@UniDocs_Mahapushpa_Cyavanaearliest dating brain fossils go all the way back to early Cambrian period. But surely, not all organisms would have evolved one at the same time, so yeah there probably were a lot of brainless animals roaming around, not all though
Some time before i found a short video matching a shell indentation and this predator's "teeth". I thought "wow, a rare video about such a rare animal". Now you make a much more in-depth video about the animal. Leave it to moth light to educate us on some of the most obscure, yet very interesting topics
I wish you mentioned Schinderhannes bartelsi, a small hurdiid radiodont from the early devonian which had a much different body to the rest of its relatives
@higgsbonbon They were likely outcompeted by fish-like body plans as free-swimmers. I think the fact that free-swimming arthropods has not really caught on since the extinction of the radiodonts is telling.
Their evolution is before arthropods, and they are called radiodonts. So they are not a derived arthropods but rather arthropods are derived from Anamolocaris relatives. For example, they don't have jointed legs. They are lopopodian's attempt to swim freely.

Sorry, I got a bit long on my post. Although it's good stuff! I knew Anomalacaris soon as I saw the image. Nice video! 👍🏻 It was really neat to learn about on those "Walking with Dinosaurs" and the other "Walking with" episodes as a kid. Pretty accurate in build and dimension to what the creatures actually were. They said if it didn't hunt this or that how did it get damaged and have scratches? First it was covered in a exo shell like armor. So "scratches" are unlikely. Perhaps it got in a fight with another Anomalacaris and it got "flexed" and that cracked it's rigid shell. The really interesting thing is in the Precambrian - Cambrian "Explosion" all life on earth went from tiny, simple and microbial and plant like life forms and suddenly jumped to large, complex definitely animal life forms without anything for them to have evolved from!! It's crazy! Like they just popped up out of nowhere fully formed!! When Darwin came up with and was further developing the theory of evolution he wrote that if we continue to dig and don't find anything for life in the Cambrian to have evolved from then he must be wrong and there must be a creator! Well... uh... we have dug and dug all over the world as deep as possible and we haven't found ANYTHING! WOW! Really?! Yep! Obviously there really is nothing to find that those large complex life forms to evolve from! Ok. So what now?! Do we just keep working the theory of evolution or just not talk about it and act like everything is fine and there's no issue to deal with regardless of the fact that there is no longer evidence for it and there actually is evidence against the theory of evolution?! And just not teach or tell about what Darwin himself wrote?! Or is it time to face and realize the Truth and Facts? Let's not hold humanity back because someone wants to continue to make big money and have their positions of power, authority, influence, admiration, comfort, wealth and decision making?! I personally want to know the truth and facts. I want to know what actually happened! None of us were around when all this happened so we don't know what conditions it was under at all times in the past! Maybe our methods of testing aren't giving us the correct results because we aren't accounting for things we weren't aware of or different conditions. Heck we calibrate our instruments and equipment based on things we know for sure, but we have only been here for a little while so we can't be sure! That test result may be fine and accurate for something a few thousand years old, but anything older than that could have been under different conditions so our calibration doesn't work for things older than that! So we can't say that we are for sure about any of the big stuff. We say that the laws of physics can't change, but we have been watching a particle called the Muon and it was a very stable particle for many decades. Then several years ago all of the sudden it started breaking the laws of physics! We have actually been observing this happen and it's very obvious that it is breaking the laws of physics, but we don't see any big articles or news reports about it! So carbon could have been produced in stars or collected or lost at a different rate than we know of now! So all methods of carbon dating could be wrong! The universe and the earth could be billions of years older than we think or only a few thousand years old! We don't know and right now we can't tell for sure! The age of the earth could be off by thousands, millions or even billions of years! Perhaps the laws of physics changing every so often is just part of it's natural cycle! Think about this. If the earth really is billions of years old then how can we say anything we observe consistently in just the tiny few thousand years we know we have been around is the normal pattern?! We can't! Not for sure! Maybe it's time we rethink a lot of things! I want to get on with that future of shining mirrored silver cities surrounded by healthy green forest on a beautiful blue ocean shore somewhere! I know it sounds corny, but you get the point. We are never going to get there if we don't start getting it right! Let's stop being prideful and insisting that we are right if evidence shows we are actually wrong. Let's get it right and make it better! Sorry, I got off on a bit of a rant there. lol. 😆 Oops! Again Good video. Thanks! 👍🏻
An intellectually honest person would not only rely upon quote-mining from a long-dead scientist, he would have looked into a subject rather than assuming he already knew everything... and realized that the absence of evidence is not immediate license for wild speculation when the most parsimonious explanation that doesn't require inventing entirely new and heretofore undescribed forces is that we simply haven't found what we're looking for. Unfortunately for you, not only have we found fossils of complex life predating the Cambrian Explosion, enough that we can speculate on the ancestry of Cambrian life, it appears that the "Explosion" part of that is a bit of a misnomer, being more an artifact of the sparse fossil record from that far back than an actual event.
What is interesting is that these early animals are like finding life on a different planet with an environment different than our present modern day Earth.
1:20. That's Antelope Canyon. It's half way between the east side of the Grand Canyon and Monument Valley. That makes for a trio of excellent destinations that you could see in a couple of days.
I second this idea. Lopopodian are stem radiodonts, radiodonts are stem arthropods. So basically just keep going back down the evolution tree. Hallucigenia is one of many lopopodian. They are an awesome lineage. That said, they evolved before arthropods so they had to make a living other ways than exclusively eating arthropods.
But if the lashing injuries on Trilobites don't come from Anomalocaris, because the shells would have caused damage to their appendages... then where do these injuries come from?
Great video! I would love to see a separate video on the Ediacara biota. They are often overlooked, and misunderstood. It is fascinating that Dickinsonia seems to be the first organism with bilateral symmetry (and potentially the ancestor of all organisms with bilateral symmetry?)
In the past months I've watched almost all your videos and I've learned from them more than I learned from all my biology and history classes combined. I would love to have the possibility to support your work somehow as I find it to be one of the most valuable available in UA-cam. You should really consider opening a patreon account or just enabling the "tip" option for each video (I'm not sure what it's called exactly). Keep up with the great content, I'm always waiting for your new videos! 😊😊😊😊
@@lukeheych8708 Yes you are right. I've watched so many of his videos that I got used to stop them before they finish. As you seem to know a lot, if not everything, could you please give me directions on how to become a patreon? I've never done this before.
Opabinia's mouth was behind the trunk. The "pincer" at the tip is a pair of appendages similar to those of Anomalocaris, but the "upper lip" segment that they grew out of was elongated into a trunk. Opabinids were really just specialised relatives of the Anomalocaridids.
All other Phanerozoic fauna emerged and descended from existing fauna. But at the Cambrian explosion animals appeared de novo, from nothing. This was the very first appearance from single called ancestors of complex energetic animals, made possible by rising oxygen levels (caused by the Cryogenian glaciation). This was nature’s very first attempt at animals, designed on a blank sheet of paper. That is what makes the Cambrian fauna so wonderful.
And together with Anomalocaris and the Radiodonts there were also some big Lobopodians that were the apex predators of the Cambrian seas, things like Kerygmachela, Pambdelurion and Omnidens which although fragmentary it's estimated to be between 1-1.5 meter (some estimates also say it was around 2 meters but Idk how reliable they are). It would be cool if you would make a video on these cool underrated animals as well.
Can you make a video about the evolution of Branchiopods? Triops are known to have lived with the dinosaurs, but the interesting part is that wikipedia says their ancestors are from the ocean. How can a sea creature from salty water evolve to master freshwater vernal pools alongside this special reproduction?
Anomalocaris is probably the first prehistoric animal I’d choose to actually be able to truly see what it looked like & how it acted in its environment. It’s just so fascinating.
The meta was wild back then. We've really stepped up our game since then. It's crazy to think what's going to happen with further build optimization... Actually, thinking about it, I assume it'll just be return to crab...
Actually, recent studies show that the Anomolocaris’ bite was not strong enough to crack adult trilobites. It instead could have eaten juvenile trilobites & scraps
Of course, it could be argued in favor of the possibility, that there were earlier super predators on Earth, but they were likely too small and/or soft bodied to fossilize, so we will probably never know of them.
I have an Anomalocaris shirt. A lot of curious questions from strangers and opportunities for me to go on about the Cambrian Explosion and the Burgess Shale lol
A request to include subtitles whenever there is a latin or english proper noun. Often times I would love to read more about a subject but it proves difficult as I cannot quite catch the precise spelling from speech alone.
Drawings of Cambrian animals fail to express how small everything was
You could say the same about satellite images of Earth
They really just don't give a sense of scale. At least with dinosaurs, you can use somewhat familiar plants, but the Cambrian is just such an alien time.
Or big, as Cambrian animals came in 2 shapes, tiny and huge

So carbon could have been produced in stars or collected or lost at a different rate than we know of now! So all methods of carbon dating could be wrong! The universe and the earth could be billions of years older than we think or only a few thousand years old! We don't know and right now we can't tell for sure! The age of the earth could be off by thousands, millions or even billions of years!
Perhaps the laws of physics changing every so often is just part of it's natural cycle!
Think about this. If the earth really is billions of years old then how can we say anything we observe consistently in just the tiny few thousand years we know we have been around is the normal pattern?! We can't! Not for sure!
Maybe it's time we rethink a lot of things!
I want to get on with that future of shining mirrored silver cities surrounded by healthy green forest on a beautiful blue ocean shore somewhere!
I know it sounds corny, but you get the point.
We are never going to get there if we don't start getting it right!
Let's stop being prideful and insisting that we are right if evidence shows we are actually wrong. Let's get it right and make it better!
Sorry, I got off on a bit of a rant there. lol. 😆 Oops!
Again Good video. Thanks! 👍🏻
An intellectually honest person would not only rely upon quote-mining from a long-dead scientist, he would have looked into a subject rather than assuming he already knew everything... and realized that the absence of evidence is not immediate license for wild speculation when the most parsimonious explanation that doesn't require inventing entirely new and heretofore undescribed forces is that we simply haven't found what we're looking for.
Unfortunately for you, not only have we found fossils of complex life predating the Cambrian Explosion, enough that we can speculate on the ancestry of Cambrian life, it appears that the "Explosion" part of that is a bit of a misnomer, being more an artifact of the sparse fossil record from that far back than an actual event.
Oh boy a new video. 😊
I guess the spiky grabbing bits are perfect to hold soft and slippery prey rather than hard shelled prey.
Thank you for a complete and detailed video!
I love that so many creatures want to be crustaceans, I do too tbh
he does his best
Cool shrimp bro
I have my anomalocaris plushie right beside me as I'm watching this lol.
Hi fellow anomalocaris plushie owner
Truly a once in a timeline animal!
I just adore this channel. I think I'm going to sign up for your patreon ❤ thank you for all you do
Thanks for the step-by-step guide. Super useful!
Pour one out for Anomalocaris, the OG killer arthropod
If there were one of those things living in my bathtub, I would move.
you forgot to mention Schinderhannes bartelsi! :P
I can’t tell you how excited I was to see you do a video on Anomalocaris!
What is interesting is that these early animals are like finding life on a different planet with an environment different than our present modern day Earth.
1:20. That's Antelope Canyon. It's half way between the east side of the Grand Canyon and Monument Valley. That makes for a trio of excellent destinations that you could see in a couple of days.
Love that the first super predator also became the first huge filter feeder.
I wonder if you could do an episode on the Lobopodians, the other group of giant Cambrian stem arthropod predator.
I second this idea. Lopopodian are stem radiodonts, radiodonts are stem arthropods. So basically just keep going back down the evolution tree. Hallucigenia is one of many lopopodian. They are an awesome lineage. That said, they evolved before arthropods so they had to make a living other ways than exclusively eating arthropods.
My favorite prehistoric creature
I love this animal
New video! Saw thumbnail. "Anomalocaris!" was my excited thought!
I love your videos so much, please keep up the great work !!
the goat uploads once more
Always liked Anomalocaris, great work as usual.
I forgot about this guy. I loVe this guy. Thankx algorythim...
compact and informative. clearly worded and orginized. youve got a new subscriber my freind. this is up there with channel quality like pbs eons.
Never clicked faster, love your videos! Hope youre doing well man
Finally! new video!
RULES OF NATURE
I like winding down/ napping to your cadence /tone. Long live moth light
But if the lashing injuries on Trilobites don't come from Anomalocaris, because the shells would have caused damage to their appendages... then where do these injuries come from?
Other trilobites, of carnivorous kind?
@@melanimatejak6821 not big enough
@@D-angelin.Moarar Wheren't there some trilobites 30 centimeters long?
Keep in the mind the study is just one of many and I personally didn’t buy it myself for a couple of reasons.
Great video! I would love to see a separate video on the Ediacara biota. They are often overlooked, and misunderstood. It is fascinating that Dickinsonia seems to be the first organism with bilateral symmetry (and potentially the ancestor of all organisms with bilateral symmetry?)
In the past months I've watched almost all your videos and I've learned from them more than I learned from all my biology and history classes combined. I would love to have the possibility to support your work somehow as I find it to be one of the most valuable available in UA-cam.
You should really consider opening a patreon account or just enabling the "tip" option for each video (I'm not sure what it's called exactly).
Keep up with the great content, I'm always waiting for your new videos! 😊😊😊😊
He shout out his patreon supporters at the end??
@@lukeheych8708 Yes you are right. I've watched so many of his videos that I got used to stop them before they finish. As you seem to know a lot, if not everything, could you please give me directions on how to become a patreon? I've never done this before.
@marcosrou in the description there is a link to sign up
@@Dman6779 thanks!
Incredible content as always, thanks!
cambrian period my beloved
what about the acorn weevil? they have a similar mouth as Opabinia
Opabinia's mouth was behind the trunk. The "pincer" at the tip is a pair of appendages similar to those of Anomalocaris, but the "upper lip" segment that they grew out of was elongated into a trunk. Opabinids were really just specialised relatives of the Anomalocaridids.
All other Phanerozoic fauna emerged and descended from existing fauna. But at the Cambrian explosion animals appeared de novo, from nothing. This was the very first appearance from single called ancestors of complex energetic animals, made possible by rising oxygen levels (caused by the Cryogenian glaciation). This was nature’s very first attempt at animals, designed on a blank sheet of paper. That is what makes the Cambrian fauna so wonderful.
Keep up the good work!!
And together with Anomalocaris and the Radiodonts there were also some big Lobopodians that were the apex predators of the Cambrian seas, things like Kerygmachela, Pambdelurion and Omnidens which although fragmentary it's estimated to be between 1-1.5 meter (some estimates also say it was around 2 meters but Idk how reliable they are). It would be cool if you would make a video on these cool underrated animals as well.
Can you make a video about the evolution of Branchiopods? Triops are known to have lived with the dinosaurs, but the interesting part is that wikipedia says their ancestors are from the ocean. How can a sea creature from salty water evolve to master freshwater vernal pools alongside this special reproduction?
I'm betting it was preadapted by developing a tough egg case for the shoreline.
Thanks for this, I really enjoy the subject of early life.
I've yet to have a video about anomalocaris show up in my sub-feed without getting at least a lil bit excited, I love these goobers so much
Anomalocaris is probably the first prehistoric animal I’d choose to actually be able to truly see what it looked like & how it acted in its environment. It’s just so fascinating.
No mention of Stanleycaris?
8:32 Everything was turning into crabs... even before there were crabs...
the best part about him is when he starts moving, he doesn't stop until he exterminate his enemies
Man can't watch an educational video with some level of maturity like damn
The meta was wild back then. We've really stepped up our game since then. It's crazy to think what's going to happen with further build optimization... Actually, thinking about it, I assume it'll just be return to crab...
Unfortunately Power creep wasn't kind to them
@@fastrockproductions9788 power creep isn't kind to anyone... Except sharks. Sharks are power creep
500 million years of evolution tells us one thing, vegetarians are food
Actually, recent studies show that the Anomolocaris’ bite was not strong enough to crack adult trilobites. It instead could have eaten juvenile trilobites & scraps
6:15 a big advantage 🤭
Great vid 👍
One of if not my favorite extinct animal
I wonder what its mouthparts are derived from
Of course, it could be argued in favor of the possibility, that there were earlier super predators on Earth, but they were likely too small and/or soft bodied to fossilize, so we will probably never know of them.
I have an Anomalocaris shirt. A lot of curious questions from strangers and opportunities for me to go on about the Cambrian Explosion and the Burgess Shale lol
wake me up inside
A request to include subtitles whenever there is a latin or english proper noun. Often times I would love to read more about a subject but it proves difficult as I cannot quite catch the precise spelling from speech alone.
Great video. As always.
So nice off to learn aboat newe dinosawrs! Tanks to u
Burgess Shale! What an amazing story it tells.
