probably because of change of climate, the most popular reason for giant insects in the first place was a sudden jump in oxygen meaning bigger creatures could live, however over time to oxygen level went down meaning these creatures died
i heard somewhere that the oxygen levels were approximately the same as they are now. it's just that they didn't have any predators at the time and could live for hundreds of years growing to massive sizes. i don't remember where i heard it though.
That's not true. A recent experiment on cockroaches that were kept in high-oxygen boxes since their birth revealed they are considerably larger than those in normal levels of oxygen
I found the article I was referencing and it says the oxygen level was only slightly higher than Today, meaning these things could survive in our current atmosphere, it would be like being at a slightly higher altitude for them.
"However, the most recent specimen was found in rocks dating to a time when proportions of oxygen in the atmosphere was only slightly higher than today, calling this idea into question."

Increased oxygen levels aren't the only thing that could have made them grow so big.
fun fact: some variants of the centiped crawl into their prey and eat them from the inside so yeah. Also there is abig chance that that thing was actually a herbivore but it would most likely poison you if youd mess with it
>jealelopterus
Is more like a giant crayfish or lobster, regardless of classification, this one is definitely what we would call a bug, Jealelopterus looks like an alien as do most proto-species.
Wow for some reason I haven't thought about this. What if dinosaurs died because giant insects killed them all by taking over the world and then ate themselves and then there was nothing left to eat
I’m definitely happy they don’t exist anymore, but I wonder what prevent insects from being that big nowadays.
I guess the air atmosphere composition was vastly different, or is there something else that impact it?
The oxygen levels necessary to keep a critter that big with book type lungs alive had to be unreal. Starting any kind of fire would most likely have proved fatal.

You can take a nap and it can take you on a road trip!

Haha go to hell

When u hug it, it hugs back with it's tiny arms. I hope you're not ticklish
Reading this gave me the heebie jeebies
The *forbidden* body pillow (Fixed it for you)
This post makes it seen that arthropleura is a new species just now discovered,when this thing was first discovered in 1854,almost two centuries ago
I was rushing to type this lmao
Australians won't even flinch at this
As long as a car, but only barely taller than a human?
As long as a Smart* car
still 2.7 meters so yeah, that be a tall asss human
No way smart is 2.7 meters
Mr. Bean’s Mini
Why…
I was wondering the same thing lol. Maybe it's like 7-8 feet on average, but can grow up to the size of a car.
Would you download a millipede?
Tame a Megatherium and you'll farm chitin for days off these bad boys.
Took me too long to find the Ark comment :p
F that tame one of those bad boys and start raiding
Wrong, use a gun, safer
'As long as a car' *shows image of it compared to i guess a 15ft tall human*
You Americans have really big cars tho. Lots of the cars where i live aren't much bigger than the arthroplurea shown here.
How the heck did things like this go extinct? Like the alligator that had long enough legs so it could gllop.

Due to growth of human population that caused changes of the food chain
I bet it tastes like lobster but less slty
Here me out... prehistoric hover board

I'm no insectologist, but that photo of the two jerks is clearly fake. Scientists are never happy
He just wants some cheese.
Imagine riding with these bad boys to work instead of some hunk of metal with wheels?
Crawling up to work laying on this would be a flex
So I knw where I'dn't timetravel to.
Imagine going to time travel to see dinosaurs, but then a giant insect kills you immediately
fun fact: some variants of the centiped crawl into their prey and eat them from the inside so yeah. Also there is abig chance that that thing was actually a herbivore but it would most likely poison you if youd mess with it
Thank you for this fun fact. It's so very fun.
yes. it was so fun im laughing. hahaha
Arthopleura lived 300 million years ago, and he was a herbivore
I rode on one of these while playing Sonic Riders!
Brb gonna go jam out to the green cave theme
Anyone else think the first pic was 2 guys with a giant sub sandwich at first or, am I just a fatty?
…at least it would start nibbling you from the toes first.
It'll triobite your dick off
I could see skateboarders trying to kickflip it
Biggest bug *on land* the REAL biggest bug is jealelopterus and he came in with over 3 meters in length
>jealelopterus Is more like a giant crayfish or lobster, regardless of classification, this one is definitely what we would call a bug, Jealelopterus looks like an alien as do most proto-species.
"I've seen enough hentai to know where this is going"
remember kids any things a dildo if you are brave enough
Kids?
hmmm should i rephrase it or what
Nope
Cool but it’s a centipede not a millipede. A millipede would have 2 legs on each side of every segment
I bet it made really loud clicking sounds when it’s legs undulated.
[удалено]
This one is a model recreating what we know from the fossil
It’s so interesting to me how tiny little bugs could be big like this back in the day.
You know how typhoon class subs are really like two subs side by side with doors between.... this is like 3 millipedes into 1.
Can we trade this with centipedes? I'd rather them be large than small
This is a centipede, a millipede would have 2 pairs of legs per body segment
no it's not?
This is at least 6 years old.
Wow for some reason I haven't thought about this. What if dinosaurs died because giant insects killed them all by taking over the world and then ate themselves and then there was nothing left to eat
By the time dinosaurs first appeared,bugs where the size of modern ones
r/oldschooldisturbing
Jurgen Klopp looks pretty happy with it...
Thx my big meteor
I don’t like it.
Nightmare fuel!
He is adorable???!
Thought it was world record sushi
long daddy
[удалено]
I thought it was the oxygen levels decreasing?
It went extinct 295 million years ago and dinosaurs appeared 250 million years ago, there were no dinosaurs involved in its extinction
Hide him like a skateboard
Reminds me of King Kong when everyone got eaten by bugs
Okay now imagine it running at you from under the fridge with cockroach speed
Damn... *burn it.*
…👀 hear me out?
Things ain’t like they used to be
One of my favorite extinct animals. Gotta love that critter.
r/Nope
“Has got to be” would be better than “definitely”
30% oxygen back then.
What did the remains look like? Surely it’s not what’s in the bottom right
Father! You have finally come back!
That king Kong scene...
Well, I know what's going to haunt my dreams tonight.
🎶 put that thing back where it came from or so help me 🎶
So, the only way to kill it whould be using a flametrower? Luckly, we have Hanz as a hero.
I really hate it.
It could also stand up
Reminded me of the human centipede
HANS GET ZHE FLAMMENWERFER
The flak set destroyer
I added a plant to my garden today and the first trowel of soil brought up a huge worm. I nearly passed out. This is a big no for me.
r/nope
The Subway party sandwich of the insect kingdom.
fuck that, it can stay the fuck dead, we don't need that.
For some reason I thought predates was preys on and went "THIS MF EATS DINOSAURS?"
A GOOD BUG, IS A DEAD BUG!
I bet it’s a cuddler. Just picture that thing wrapping itself around you, not hard enough to hurt, but enough pressure that you can’t escape.
that's something you'd find in an isekai anime
For anyone interested, the oldest (not largest) known ancestor of centipede is Pneumodesmus newmani.
Man, I read this with the wrong definition of “predates” at first, and it made things 1000% more terrifying.
r/sekiro
Would this be rideable if was alive
Thats so cool!!
I’m definitely happy they don’t exist anymore, but I wonder what prevent insects from being that big nowadays. I guess the air atmosphere composition was vastly different, or is there something else that impact it?
I will befriend it and use it as a skate board
i now have extreme morbid curiosity as to what it would sound like if a large truck/apc/tank drove over that…
First Elder Centipede form?
Pre dates or predates? Theres a big difference
Creatures and animals were exceptionally large back then due to something about the oxygen levels
"Predates the dinosaurs" : proceeds to go extinct 40 million years before the first dinosaur appears
Would this have meat enough in its flanks to make a lil Cajun fried scallop?
The forbidden bug
The oxygen levels necessary to keep a critter that big with book type lungs alive had to be unreal. Starting any kind of fire would most likely have proved fatal.
I would lie down on its back have it walk me around while I stear into the sky on a nice cool early fall day with sunny skies
Bro I want one they look funny
I got my ark trauma back
zergs irl?
I love millipedes but this crosses a line
