🌍 Dinosaurs, those magnificent creatures that once roamed the Earth, continue to captivate our imagination and scientific curiosity. The era of dinosaurs began approximately 230 million years ago in the Mesozoic Era, marking a period of dominance by these fascinating reptiles. Before dinosaurs, appearance of the dinosaurs and after the dinosaurs. This age, often referred to as the "Age of Dinosaurs," witnessed the emergence of some of the most iconic species, from the towering Brachiosaurus to the fierce Tyrannosaurus rex. Their existence demonstrates the incredible diversity and adaptability of life on Earth, with species that thrived in a variety of habitats, from lush forests to arid deserts.
The extinction of dinosaurs, about 66 million years ago, remains one of the most intriguing topics in paleontology. This catastrophic event, believed to be caused by a combination of volcanic eruptions, climate changes, and the impact of a massive asteroid, led to the end of the Cretaceous Period and paved the way for the rise of mammals. The sudden disappearance of dinosaurs left a void that has puzzled scientists for centuries, sparking numerous theories and extensive research to uncover the details of this mass extinction.
Beyond their appearance and extinction, dinosaurs are a source of endless fascination due to the strange and sometimes bewildering facts that research has unearthed. For instance, some dinosaurs, like the Stegosaurus, had brains the size of a walnut, significantly small in comparison to their massive bodies. Others, such as the Parasaurolophus, had elaborate crests on their heads that could have been used for communication or to attract mates. The discovery of dinosaur fossils with preserved feathers has revolutionized our understanding of these creatures, suggesting a closer evolutionary link to birds than previously thought.
The pre-dinosaur world, often overshadowed by the towering presence of the Jurassic era's giants, presents an equally fascinating chapter in Earth's geological history. This epoch, spanning from the formation of the Earth around 4.5 billion years ago to roughly 250 million years before the appearance of the first dinosaurs, encompasses several pivotal periods that laid the groundwork for life as we know it.
During the Hadean and Archean eons, the Earth was a molten hellscape, gradually cooling to form the first solid crust. This era saw the emergence of the first life forms, simple prokaryotic cells, which appeared approximately 3.5 billion years ago. These organisms were primarily anaerobic bacteria thriving in an oxygen-free atmosphere, setting the stage for the evolutionary leaps to follow.
The Proterozoic eon witnessed significant geological and biological transformations. This period marked the accumulation of oxygen in the atmosphere, a direct result of photosynthesis by cyanobacteria. The "Great Oxygenation Event," which occurred around 2.4 billion years ago, radically altered the planet's atmosphere, paving the way for more complex life forms. The Proterozoic also saw the first supercontinent, Rodinia, form and break apart, a cycle that influenced global climate and environmental conditions conducive to evolution.
By the late Proterozoic, around 600 million years ago, the first multicellular organisms began to appear, with the Ediacaran biota representing some of the earliest complex life. These creatures were predominantly soft-bodied, living in the deep sea environments of Earth's pre-Cambrian oceans. They lacked the hard, mineralized skeletons that would become commonplace in later eras but represented a critical step in the evolution of life.
Transitioning into the Phanerozoic eon, the Paleozoic era, specifically the Cambrian period, known for the "Cambrian Explosion," saw a dramatic diversification in life forms. This period, beginning around 541 million years ago, marked the emergence of most of the major groups of animals and the first occurrence of a predator-prey dynamic. The Cambrian Explosion set the biological stage for the development of ecosystems that could support the eventual rise of dinosaurs in the subsequent Mesozoic era. - Věda a technologie
I miss those days when we were single cells lounging around our hydrothermal vents.
It’s been downhill ever since.
signs of the time, degeneracy of the modern age
Great video but the narration is unbearable.
Put it on 1.5x speed
It's an AI voice from 11 labs. Report and move on.
Good documentary, a lot of information
it is cutious the shape of this creature , because , if you have a slow reaction to your optic nerve blind spot, ie due to medication , this is the exact shape you can see of the shadow until you bline and your eye moves and maps over your blind spot.
for a long time i woke up seeing a giant hairy floating catepiller , untill i told myself its just a atifact. once even thowing a cushion straight though the object.
i wonder if pimative fears of things moving in the dark are a result of such reactions. that the human body is capable of being tricked in to a primeaval fear.
PS (I have to use replys as addblockers take the comment primary button away , lol , sorry bud , and also you are at top of list so greater chance of my reply being read , a)
I've studied some of these things. I'm behind much of what is proposed in this video (I'm 22 minutes into it now), but some parts I don't concur. Example: the building blocks of life developed inside hole-pocked rocks. Also, the AI narration is grating. Can Wondody find a real person to narrate?
This AI narration is terrible get a real human to do it
Welcome to the deluge of AI-generated schwag. CZcams was already inundated with new content every minute. I can't imagine what it is now. I'm waiting for them to limit uploads considering other sites have had to do the same. We'll see, though. They've got tons of money. In the meantime, hunker down and get ready for more and more AI-generated crap to fill up your recommendations. Ugh. 🙄
ChatGP give me a quick recipe for primordial soup, and what wine pairs well with that
@@tonray9395 Your either a bot or a drone.
@@CybershamanXHow about contributing to fix these issues instead of just voicing complaints & overall negativity? & plz don’t put that emoji like you’re rolling your eyes at me. I find that highly irritating.
@@LordOfThePancakes What issues? What "problems" is this crap solving. 🙄

Great video but bad narration.
Nice documentary and exactly, what I always proposed about the building of the first, primitive cells, when studying geology at Heidelberg university.
But, I personally think, it was not done with the black smokers. The washed out cells must have had some protection against the harsh UV radiation, else the membrane would have been instantly destroyed, as soon as they came near the ocean surface...
So, presumingly a porous magmatic rock (basalt) might have been a subtrate to settle and I think, that stromatolithes came a little later, as the cells firstly needed time to adapt to the radiation.
The thumbnail is very misleading.
My Grandpa would have found this amusing.
The AI have emphysema or something? It does not appeal.
3 headed gophers sent to the cornfield.
God, but that voice grates on the nerves
I think of mud skippers.
Still with this horrid Forest Gump narration bot! Awful!
I came to say the same thing... what in the Forest Gump chit is with this narration 😅
Forrest was shot in the buttocks.
Jenny...... Jenny was made rocks and water and lightning and the sun,and that's all I have to say about that.😂
Screw this!!!!!!!!
These are ugly but not near as ugly as auntie max.
