The Forgotten Era: What Really Happened AFTER the Dinosaurs Went Extinct ? Earth History Documentary
Ғылым және технология
🌍 Today, many extinct animals are more familiar to us than some species that are still alive. Among them are the dinosaurs. The diplodocus is more famous than the aardvark, and the tyrannosaurus more famous than the peramete. Dinosaurs are part of popular culture. For over 160 million years, these majestic creatures dominated the Earth, occupying most ecological niches and leaving little room for other species.
On five occasions, the Earth was confronted with major upheavals that had a fundamental impact on its subsequent history. When they disappeared during the fifth mass extinction, the dinosaurs left an immeasurable void. But one man's misfortune is another man's gain, and this void enabled the evolution of mammals and birds, which are now highly diversified groups of animals. Without this extinction, dinosaurs would probably have continued to dominate life on Earth, and other animals would not have had the opportunity to make their mark.
Mass extinctions change the rules of the game, redistributing the cards by condemning certain groups and giving new opportunities to others. When the dinosaurs disappeared, our distant ancestors survived.
What did the Earth look like after the extinction of the dinosaurs?
🔥 As a reminder, videos are published on SUNDAYS at 6pm.
-------------------------
💥 How did life on Earth recover after the cataclysm that brought down the gigantic dinosaurs? :
- A mass extinction is an event that resembles a relatively brief biological crisis on the scale of geological time. At least 75% of animal and plant species disappear from the face of the Earth. Over the last 500 million years, life on the planet has undergone five mass extinctions. Today, over 99% of all organisms that have ever lived on Earth have disappeared.
The phenomenon of species extinction is no longer surprising. Species are deadly. Each of the great mass extinctions has played a role in the history of the living world, forcing it into new directions as decimated fauna and flora are forced to evolve.
The Ordovician-Silurian extinction took place 444 million years ago. A geological event triggered an episode of glaciation. Considerable quantities of water became trapped in an ice cap three times the size of present-day Antarctica. This event led to the disappearance of 85% of all terrestrial species.
The Devonian extinction began 383 million years ago. Probably due to a strong volcanic episode, pulses caused a sudden drop in oxygen levels in the oceans. 75% of species disappeared during this mass extinction.
The third mass extinction, the Permian-Triassic, took place 252 million years ago. It was the worst catastrophe ever experienced by life on Earth. Over 90% of all species were killed. The destroyed forests will need more than 10 million years to recover.
Around 200 million years ago, the Earth suffered the Triassic-Jurassic extinction. Geological events caused a warming of the Earth's surface and an increase in the concentration of carbon dioxide in the atmosphere. This was a further blow to life on Earth, which lost up to 80% of its terrestrial and marine species.
The fifth and final mass extinction was the Cretaceous-Paleogene extinction, which caused the disappearance of the famous non-avian dinosaurs.

Pangea split up well before the Cretaceous extinction event, these events occurring about 200 million years ago and 66 million years ago respectively. If you looked at Earth from space at the time of the final extinction event, you would have been able to identify each continent, even though some features might seem different or were under water at the time. Spinosaurus and Tyrannosaurus didn't live during the same time frames. Spinosaurus lived between 99-93 million years ago, whereas T-Rex roamed the Earth between 68-66 million years ago. That's just a few of the issues I caught in about the first 20 minutes.

What i find most interesting is that dinosaurs were wiped out and earth was pretty much inhabitable.. yet slowly with time, new life was born and evolved into what we have today. So it's safe to say.. even on planets that seem deserted or couldn't possibly harbour life, given enough time and evolution.. can as well. Because it happened here.

I mean is it really odd? Superspecialized animals are the most vulnerable to environment changes and crocodiles are one of the biggest generialists that there are. They evolved as fish eaters but instead of specializing at becoming better at catching the more elusive fish (and later sharks and other bigger deeper water animals) as some of the prehistoric ocean reptiles, somewhere along the way they decided "fuck it, this shallow water fish is good enough" and instead in addition to that talking in gaming terms started to abuse probably one of the of the most broken things possible - camping at the water sources for occasional but also inevitable bigger meal. Crocodiles are kinda both generalist and occupiers of one of the most reliable and least impacted by big environmental changes niches possible at the same time which is why they are to this day more or less the same as they used to be during the times of dinosaurs (outside of temporary reduction in size after the asteroid cataclysm).

What do Neil deGrasse Tyson, Bill Nye, Brian Cox and thousands of their fellow "Evo-Bang-Bangs" have in common?? All of them utter the mentally devolved phrase, "MALLIONS AND BALLIONS OF YAYERRRRRS AGO", which is "Snake-Oil Salesman Speak" for, "We have no idea". These "Evo-Bang-Bang" scientists radio-carbon date fossils blindly, with absolutely ZERO reference to what the Carbon-14 saturation of Earths atmosphere was, at the time when the fossilized creatures took their last breath. They don't even have the common sense to realize that every fossil that they carbon-date has Carbon-14 in it. Ok, anyone would say, "Of course they have C-14 in them, so what??". Well, C-14 being present is what destroys everything they've been telling us. The Facts are: 1) Everything in the Universe is dying. Every atom in the periodic table has as "Rate of Decay" and is measured by its calculated "Half-Life". 2) Carbon-14 has a Half-Life of only 5,730 yrs (+/- 40yrs). Its rate of decay is exponential and doing rough-calculus in my head, its full-life is 11,000-15,000yrs at most, before it fully decays into Nitrogen-14. So absolutely NO dinosaur fossils are found without Carbon-14 and if people use their brains will realize NONE of them are lol, "MALLIONS AND BALLIONS OF YAYERRRRRS OLD". Seems like, not only is the Earth very young, but the Universe is young as well. Just a thought but, if the Universe is "BALLIONS OF YAYERRRRRS OLD", in just our Milky Way Galaxy alone with billions of stars, we should be privy every night, to a grand celestial fireworks show of at least 500-1000 stars going supernova, from accidentally bumping into each other. In 70yrs, astronomers have witnessed what, 3 or 4?? Also, astronomers have kinda let the "cat out of the bag". They say that radiation readings from the so-called "Big Bang" are the same from Earth in every direction, as if the Earth is in the center. Well doesn't it say in Genesis that God spread out the Heavens? Since He created Earth first in Genesis 1:1, the Earth would be the center of the universe.

Well mammals was already present during the late cretaceous period. If it wasn't for the asteroid, Earth would have suffered a new icy age anyway since that stuff is cyclical. So large dinosaur megafauna would have adapted or hit extinction. What people usually ignore is the fact that dinosaurs average dimensions was around that of a cat till that of a cow. Then there was the megafauna. Those large animals we see in the movies. It seems also that species like the T-Rex was part of the megafauna. But the average size is way smallers so, once the icy ages hits, many species would die and mamnals would thrive occupying those niches. In the end, even without asteroid, Earth today would have been similar to ours with just more species of reptile/birds like creatures. Most of the fauna anyway would have been made by mammals due to the fact that mammals are more competitive than reptiles, birds and dinosaurs. It was stated that dinosaurs for example had mix blood. Not warm blood like mammals, not cold blood like reptiles, but mixed. While mammals with their fast life cycle and methabolism are just better suited to adapt to the most extreme environments. We find for example mammals that lives from the most hot temperatures on the planet to the most freezing. With a slight preference for cold environments. Probably in the case of no asteroid impact, dinosaurs would have remained in the hot zones while mammals would have occupied the coldest ones. I mean, they would have dominated or had more species than the average in those climates. While in hot environments the dinosaurs would have had the supremacy.

What do they think happened when the earth was covered in plants, there was more oxygen in the atmosphere, and a fire started with nobody there to put it out? Or when lots of volcanoes were erupting? Climate change happens with or without humans.

Yep - It's a no brainer...lol. The climate will change regardless of humans and our activities. History and geology show that. There's big money to be made from the global warming scam/emergency that our elites insist we are having. As far as human extinction goes they did a real job on us recently with the lab virus that they inflicted on us in 2020 - the lunatic elite politicians are more likely to cause human extinction because they are too stupid to grasp a basic understanding of how viruses work yet they persist on fooling around with them in their shonky labs. We are in the hands of fools.

This is true. However, human activity affects it. All that oxygen produced by plants came from carbon dioxide that the plants brothe (heh.. breathed). They took the c out of the co2 and released the o2, keeping the c. They made a difference. They eventually became crude oil. When humans burn that oil, the fire takes in o2 and releases co2, returning the c into the atmosphere, gradually reversing the process that the plants originally performed. After burning shit-tons of oil over many decades, a significant amount of o2 gets converted back into co2, enough to have an effect on the climate. Its small compared to all the other natural processes, but enough to eventually make a gradual difference

Think about it. You admitted the plants made a difference. If that difference gets undone to some extent, that will eventually lead to a measurable effect. When done on an industrial scale, why wouldnt it cause change? Humans are pretty good at burning plants in all their forms, including the ancient ones whose matter has become crude oil

I disagree that its mainly caused by human activities. Its partially caused by human activities. However, there is a tipping point at which one type of change triggers another type that contributes to the overall change that ends up snowballing into a particular direction
I thought Titanosaurs were larger than diplodocus and brachiosaurus, particularly Patagotitan and Argentinasaurus
I do quite enjoy that the video comes with a context message about climate change being "mainly caused by human activities" when the content of the video relates to climate change before hominids evolved.
I love the fact that they use Jurassic Park evolution video game footage in this
At about 1:42, there's a Triceratops skull sitting in front of what appears to be Stegosaur ribs and spinal section. Triceratops lived during the Cretaceous Period (145-66 mya) while Stegosaurs lived during the earlier Jurassic Period (200-145 mya). At 10:24, why is there a submersible in the background behind the Mosasaur?

Naming things after unrelated things that they vaguely remind people of, is extremely common.
I find it funny that the skeleton at the start of the video was a triceratops head on a stegosaurus body. Bearing in mind that besides the obvious impossibility of this creature existing, stegosaurus died out around 70 million years before the last triceratops died out due to the extinction of the dinosaurs.

After every one of those mass extinction events, life rebounded. Not only that, but it evolved into ever more complex species. If not for all of those mass extinction events, humanity would probaby not have evolved. So we should not think of them as negative events, but necessary events.

The weight and size of the largest dinosaur was wholly dependent upon the prevailing atmosphere's percentage oxygen level. Over the dinosaur's reign, The Earth's atmosphere had -- at its Zenith -- accumulated to perhaps 40%. As it fluctuated more or less over tens of millions of years, that range between was as much as 25 to +3% from current levels. Thus was an established "top-size" for any given period.

An interesting video. Much guess work, likely some accurate, some not, since there were no humans around during most of the time. And even after humans appeared on the scene, we didn't begin recording our history till fairly recently. This video presents as factual and only about the theory of evolution. What if the theory of evolution AND the theory of creation are both true? What if the creators infused early primates with the DNA of a different species and allowed evolution to take its course? If so, who were the creators? Do they still exist? Do they still visit earth to see how their experiment is coming along? Where did they come from? I can see and understand how some believe one thing and some another. It seems to me however, that we really don't know much of anything. All we can do is attempt to see into the past and try to figure it all out. It is after all what we do, isn't it? Just like we have always looked to the horizon and wondered what was beyond that mountain or that sea or ocean. And we go. Our natural desire and hunger for knowledge pushes us forward into uncharted territory. It drives us to risk it all to learn what we don't know. Enjoyed your video.

The word, "prey" is misused in this. It is not "a prey" or "preys". "Preys" is a verb, not a noun. "It is not prey," would be the proper grammatical construction for that earlier sentence. Or, "it is not a prey animal." Also, you listed pterosaurs with the birds, while talking about archaeopteryx. Pterosaurs were independent of bird lineages.
