When man came into the picture, food sources reduced. Climate change impacted food sources. There was competition between species to survive. That's why most of those species died out when modern man came about. Our ancestors were trying to hunt everything (while they were still some where in between the food chain).
The Age Of Mammals was always almost more interesting to me than the dinosaurs growing up. Yiu had the short faced bear which was twice as big as a grizzly, dire wolves twice as big as grey wolves, the giant savage and carnivorous ancestor of pigs, wooly mammoths, the titanoboa, megalania in Australia, etc.
Disagree, dinosaur Is wayyyy more interesting than the extinct mammals, cause we know nothing about them. Only from fossil and study, but not accurate proof
I love dinosaurs, don't get me wrong. They are some of the most miraculous animals to exist. However, the Paleozoic has to be my favorite Era. It's so unique and you see how truly alien life gets during its beginning.
Slight clarification on Andrewsarchus: it's NOT only related to sheep and goat, it's related to two-toed ungulates including BUT not limited to - Whales, deer, pigs, and also sheep, ect. I think this fact is much cooler than they way they presented the creature.
Yea like megalodons teeth are as big as humans lol. We actually currently have various teeth from megalodons. They are huge but not the same size as humans.
Yeah, the reason they were so big was because of the atmosphere around them was literally different from today's. There was a heck of a lot more oxygen in the air, which contributed to the larger sizes of just about everything. During extinction events, because there were several way worse than the one that killed the dinos and the ice age, the planet went through living nightmares as a result of the food chain crashing. So, because these creatures were so big, there wasn't enough vegetation for the plant eaters which killed those animals, and there wasn't enough of the plant eating animals for the meat eaters. So, that's one reason that smaller animals lived. They didn't need as much food for energy, and the smaller ones usually had places to chill underground or whatever and hibernate until it was cool to come out. Another reason to downgrade in size was because of food costs. Think of it like a video game. If you're solo, it's harder and harder to get food if you eat everything in sight. And, if you're big and you're in a party of fellow big players and you take down a boss, you have to split the loot between the group, the more players, the less loot you get between the group. Which is why when you're smaller, it works better. It's why wolves and lions got smaller from their bigger ancestors. Also bears, but bears don't hunt in groups. The smaller size means less food costs, the group individuals get more bang for the buck per kill, and you still have a viable food source hanging out because you didn't merc everything in the area. It just works out that way. SCIENCE!!!
Only the invertebrates were bigger because of the extra oxygen content, and that was only in the carboniferous period, about 300-320 million years ago. Other animals are not constrained in size by how much oxygen there is; only invertebrates (its to do with their method of breathing, which is different to ours). Other animals grew large at Other time periods in earth's history for different reasons. Some plant eaters grew tall, so they could reach leaves on the top of trees, and had large bodies, so they could process the food. Large predators evolved too, in order to still be able to hunt some of the plant eaters (although some plant eaters grew so big, they likely had no predators). After the dinosaurs died out, it took their mammal successors(which were small) several million years to grow large in size. Then we saw an era of giant mammals, which lasted until around the last ice age. Deer, pigs, wolves, bears, cats and even sloths are all related to giant versions of themselves that died out just a few tens of thousands of years ago.
Funny thing about Megapiranha: the modern piranha species are predators, but they're actually near the bottom of the food chain and are prey for a lot of animals. Botos, giant river otters, arowanas, dozens of species of fishing birds, they all feast on piranha. Megapiranha may have been about three feet long, but it lived alongside other giants like the thirty-foot caiman Purrasaurus, the giant snake Titanoboa, other even larger fish, and more that would have eaten them with equal relish. So even the horror movie version of the piranha was a low-chain dweller.
Everything smaller now because there is less oxygen in the atmosphere if the oxygen levels went back up all animals would grow again and we would die because we’re not built for that level of oxygen consumption we would be enhanced for a short time but we would get oxygen poisoning in the end its a video on RUclips that explains it better 🤷🏽♂️
The video you reacted to was full of shockmongering nonsense and misinterpreted facts. 1) The megaladon's teeth were NOT the size of a human. Their WHOLE JAWS were the size of a human. Its teeth were the size of your hand. 2) Andrewsarchus was just another mammalian predator. It would have been no more dangerous than a big cat. They were RELATED to animals that later became sheep, not ancestors. 3 ) Pulmonoscorpius was only a foot long, not as large as the fearmongering pictures claimed. Only ONE specimen was 70cm - which is barely over TWO feet, not the huge 4' - 6' they showed. 4 ) The Megapirahna was smaller than most sharks, and if it ate like its modern relatives REALLY do, would probably be less dangerous. 5 ) Gigantopithecus would have been just a big ape. Its diet was herbivorous, and likely would have been more like a gorilla than a chimpanzee - thus, not a huge problem if it lived alongside early man. 6 ) Based on dentition, Titanoboa was most likely piscivorous. It ate fish, not crocodiles or people. 7 ) Terror Birds ate "horses" that were early forms - from the Eohippus, about the size of a large terrier, to variants only about 4' tall of various species. IF they ate horses at all. A 330 lb bird is not "larger" than a thousand pound full grown horse. In addition, the earliest homonids were LITERALLY an ocean away from the phorocycids.
@@yeboiyeboi9784 Well... 1 ) There's still a large debate about Andrewsarchus, since all we have to go on is a single skull. And if based on the proportions of an Entelodont, which has the closest shaped skulls, it would be barely larger than a Tiger, and smaller than some Smilodon breeds, and bears such as the (extinct) South American Short-Faced bear. There is also debate on if it was a predator, or a scavenger. 2 ) That's what I meant by "the size of a human" - I should have been more clear than that.
@@yeboiyeboi9784 And, like the paleontologists, we can agree to disagree. That doesn't change my core point about the video though - such as Pulmoscorpius, Titanoboa, etcetera.
The thing about Megalodon's teeth being the size of a human is false. A megalodon's tooth only measures up to 6.9 inches in length. This does not mean it wasn't the apex predator of it's time however, as it still could've fit 3 humans in it's mouth at a time. (Also in the video, they absolutely butchered Helicorprions name. It's pronounced: Hel-ee-corp-ree-on, not Heli-cop-ryan.
Titanoboa is literally Yawn from Resident Evil. Just Saiyan. Fun fact: it was discovered that Titanoboa's diet was mainly (like, 92% of it's daily ration) fish, not mammals or big lizards. It wasn't vegetarian, but wasn't downright carnivorous as well...probably could've been tamed/domesticated, if humans were around. As for reasons for extinction (other than meteorite, or ice age, or *HOOMANS* ), it's actually quite simple: such giant body requires A LOT of calories and calcium to sustain bones and body structure, so it was actually very hard for such creatures to ever feel "full" after a meal, because they needed to eat A LOT of proteins and vegetation to not fall into catabolic state and die out due to malnutrition. Big body consumes a lot of oxygen, which in on itself produces more lactic acids, which in their turn affect speed of aging of musculature, leading to overall deterioration in quality of "meat" on your body. And these "big guys" consumed IMMENSE amounts of oxygen. So they "aged" fast. And were NEVER EVER not hungry. And, well...that's what exactly happened, eventually. They starved out, because they ate nearly everything around them, including even their own kind, so it was literal extinction due to "resources" completely depleting out around their habitats. And, of course, such factors as natural disasters and, yes, arrival of *HOOMANS* (eventually, in later cases) greatly added to that as well.
Surprised you hadn't heard of some of these; guess you haven't been on tumblr in a while, huh? I first heard of Titanoboa there & saw a picture of the skeleton (head was all the way to the floor while the tail was practically touching the ceiling - & it was coiled). Also guess you haven't watched History, National Geographic, or Discovery channels, huh? Lots of shark stuff there, including stuff about Megalodon.
Both were either false or deceptive. The "horses" the Terror Birds / Phorocycids ate were tiny pre-horses, like the Eohippus that was the size of a large terrier. And the Titanoboa did NOT eat crocodiles. The teeth and size implies they ate fish.
You shouldn't be watching "The Richest." These guys are TERRIBLE with information. These idiots tend to stretch the truth VASTLY. "The Richest" is neither worth watching nor subbing to.
But every animal pretty much ran for the hills when we haunted them even predators terror birds were not a peg down in the food chain by a big cat. So those birds wouldn't last long trying to steal food or make us into their next launch we would kill them fairly easily

That's why most of those species died out when modern man came about. Our ancestors were trying to hunt everything (while they were still some where in between the food chain).
I believe it was when human started multiplying and cutting down trees in mass. Severely thinning and reducing oxygen in the air along with resources

This is the major reason I unsubbed from them.

Hows everyone doing? Whats something good you found out/did/happened to you recently? Keep safe xx ❤️❤️ Ash
Lolll. I use to live in that time were those animals were. Not gone yet loll the one that can only run fast
Big animals, more target for spears! YEET!!!
Can you guys react to amp love and basketball? Btw love y'all vids.
Can ya'll react to Steve Harvey "y'all country as hell"
And
Bernie Mac "The Hammer"
You'll laugh ur ass off
One tooth from a megalodon was not the size of a human.
Bout 7 inches
Imagine the Meg in the ocean now
Probably still is
Thank God it’s been extinct for 2 million years
Cute dog ❤
Thanks
Can you react to bas“the Jackie” ft j Cole and lil tjay ❤️
