🌍 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.
The pre-dinosaur world is a testament to the dynamic and ever-changing nature of Earth, showcasing a history rich with climatic shifts, tectonic movements, and evolutionary innovations.

Great video, thank you very much. However, I also would like to point out that there are no stegosaurian fossils from the Late Cretaceous. The iconic Stegosaurus, frequently depicted here, certainly didn’t witness this extinction 😊

[@Walgriff]

The last 15 mins should be edited out.

[@PeterSwinkels]

Indeed.

[@-Blackberry]

Nice video, but please don’t refer to Quetzalcoatlus as birds.

[@Ralph-em8xh]

Great video dude. Nice mellow voice and great graphics. Also very much appreciate you using imperial slash American measurements like miles etc. Don't have to try to convert to useless metrics. They tried to get us to learn it in the early seventies but no one wanted to know about it.

[@JerryThomas-xc7ur]

This is an awesome video, way better than any like it The reason that this one is better, it explains everything with more details. Videos like this always say the same thing. This is the best version of them all. Why is the ending, long and nothing is shown. Nothing is being heard.? ❤

[@joshbrown990]

This video feels like a third draft that needs further editing.

[@FloozieOne]

What a GREAT video. I knew pretty much all the sequences following the collision but wasn't aware of how deadly the Earth had become. It's one thing to say 75% of terrestrial life died out and 90% of aquatic animals did the same, but to describe these things in detail and with explanations for each type of creature was fantastic. I had never understood the reason for the marine extinctions but your discourse on the plankton demise finally made me realize how the food chain broke. Thanks for this lesson and I hope to find more in your other videos.

The title is Completely miss leading.

[@danielmcdonough1440]

YES!!! The last 15 minutes or so is nothing. FYI, otherwise great video 👍

[@NickPax]

I love ads...

[@blakespower]

I still dont understand why no 4 legged dinosaurs survived I think some disease must of wiped them out and bird lineage of dinosaurs were the immune ones

[@Angie2343]

Jurassic Park fans, take note.

[@burritomama2944]

why is there a large dark chunk of video after the ending? is that just me??

[@FloozieOne]

I have no idea. It starts shortly after what is supposed to be the mid-point of the video so it is only about 37:30 mins long, not 53:15. Did you experience this in any other videos in this thread?

[@Ccyawn123]

Maybe it was put there on purpose so we could quietly reflect and contemplate the sad plight of the dinosaurs

[@paladnia]

Rather sure the earthquake that happened when the proto planet Theta struck the earth, was far greater than the one that killed the dinosaurs. Good video otherwise. So many miss the fact the the spot that this happened had so many harmful elements. Sulfur comes to mind, the resulting acid rains probably lasted decades.

[@thewhitedoncheadle8345]

whats an erbivore

[@harrietharlow9929]

An animal that eats plants.

[@basildog007]

EASY!!!! The answer is: the trinosaurs!

[@jameswillett2403]

Wait, did God throw the asteroid??😂😂

[@MollyKuehl4790]

Only the weak will inherit the earth LOL I see what you did there only the meek shell inherit the earth from the Bible
