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.
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).
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.
In these chaotic times it brings me immeasurable calm to listen to your soothing narration and watch a video on the awesome breadth and wonder of our Earth's natural history. Thank you.
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.
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.
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.
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.
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
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.

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

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 😁
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.

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
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.

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.
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 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?
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...
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.
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.
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.
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.
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.
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.
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! 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?)
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.
Actually, recent studies show that the Anomolocaris’ bite was not strong enough to crack adult trilobites. It instead could have eaten juvenile trilobites & scraps
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

Pour one out for my boy Anamalocairs. Gone, but NEVER forgotten. Also I love how when it was initially discovered scientists couldn't make heads or tails of what Hallucagenia was. Literally, they couldn't decide which side was the up side, and some people thought that it walked on its spikes for whatever reason.
Thank you for creating & sharing this! BTW in 1:27 you say, "The sunshine on the primitive landscape only lasted 21h". Could that be a mistake - how long would have been a whole day then in that period?
Earth rotated faster in its early history and has been slowing, gradually and over geologic time. A Wiki article sums up the sources here: en.wikipedia.org/wiki/Earth%27s_rotation And for example, an Earth day, 2 billion years ago, was 19.5 hours. www.sci.news/othersciences/geoscience/earth-day-length-12093.html
My university professor was the one to discover the anomalocaris eye, and by accident. They were filming B roll for something (a documentary, if I remember correctly), so were breaking open random rocks without paying much attention. And then there it was.
Drawings of Cambrian animals fail to express how small everything was

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.
I KNEW it!!!
No WAY was something THAT early was so specialized!
I love this channel 🤟
I love those fossils at 4:33 with golden haloes like some kinda Elden Ring enemy
mantis shrimp always reminds me of this creature
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.
I love that so many creatures want to be crustaceans, I do too tbh
Oh boy a new video. 😊
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.
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.
WAKE ME UP
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
Truly a once in a timeline animal!
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.
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.
Pour one out for Anomalocaris, the OG killer arthropod
you forgot to mention Schinderhannes bartelsi! :P
the goat uploads once more
If there were one of those things living in my bathtub, I would move.
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.
New video! Saw thumbnail. "Anomalocaris!" was my excited thought!
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.
Cool shrimp bro
I forgot about this guy. I loVe this guy. Thankx algorythim...
Always liked Anomalocaris, great work as usual.
I just adore this channel. I think I'm going to sign up for your patreon ❤ thank you for all you do
I can’t tell you how excited I was to see you do a video on Anomalocaris!
Thank you for a complete and detailed video!
I have my anomalocaris plushie right beside me as I'm watching this lol.
Hi fellow anomalocaris plushie owner
Thanks for the step-by-step guide. Super useful!
My favorite prehistoric creature
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.
I like winding down/ napping to your cadence /tone. Long live moth light
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.
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.
For the first predator they made it great, and this video was absolutely great
compact and informative. clearly worded and orginized. youve got a new subscriber my freind. this is up there with channel quality like pbs eons.
Can anyone help with what is meant with the statement “The sunshine on the primitive landscape only lasted 21 hours” as it has me very confused.
Incredible content as always, thanks!
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
I wonder what its mouthparts are derived 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?)
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 love your videos so much, please keep up the great work !!
Finally! new video!
I love this animal
Actually, recent studies show that the Anomolocaris’ bite was not strong enough to crack adult trilobites. It instead could have eaten juvenile trilobites & scraps
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
cambrian period my beloved
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
Keep up the good work!!
No mention of Stanleycaris?
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 RUclips.
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!
Thanks for this, I really enjoy the subject of early life.
Pour one out for my boy Anamalocairs. Gone, but NEVER forgotten.
Also I love how when it was initially discovered scientists couldn't make heads or tails of what Hallucagenia was. Literally, they couldn't decide which side was the up side, and some people thought that it walked on its spikes for whatever reason.
Looks like an animal HP Lovecraft would have dreamt up!
Never clicked faster, love your videos! Hope youre doing well man
So nice off to learn aboat newe dinosawrs! Tanks to u
Burgess Shale! What an amazing story it tells.
One of if not my favorite extinct animal
Thank you for creating & sharing this! BTW in 1:27 you say, "The sunshine on the primitive landscape only lasted 21h". Could that be a mistake - how long would have been a whole day then in that period?
Earth rotated faster in its early history and has been slowing, gradually and over geologic time. A Wiki article sums up the sources here: en.wikipedia.org/wiki/Earth%27s_rotation
And for example, an Earth day, 2 billion years ago, was 19.5 hours. www.sci.news/othersciences/geoscience/earth-day-length-12093.html
My university professor was the one to discover the anomalocaris eye, and by accident. They were filming B roll for something (a documentary, if I remember correctly), so were breaking open random rocks without paying much attention. And then there it was.
He just keeps moving forward..
Favorite animals. They are just so unique.
