What Was Earth Like Before the Dinosaurs?

Millions of years ago, Earth looked very different. All the continents were fused into one, teeming with life that was both beautiful and terrifying. When you think of prehistoric times, you might picture a T. rex rampaging through the jungle with its razor-sharp teeth. But even before the dinosaurs, there were other giant creatures ruling the Earth.

Props to the cameraman for his hard work who has filmed this all.

It's crazy to think how much time passed in those periods. Millions of years.. imagine how many creatures lived and died during that time.

[hereandnow]

I can't even wrap my mind around how different life was back then. Their way of experiencing the world and the world itself would be completely different. Such a fascinating thought.

[Zero_dice]

I remember it all this. Trust me guys, it was really tough.

[jesseoliver]

Imagine how long it would've taken to walk from one end of Pangea to the other.

[Artificial_IntelligenceX]

I'm glad this guy is an ancient immortal and able to teach us about creatures that existed back then.

Too bad the dinosaurs didn’t have a government to tax them to save em from their climate change.

[Rinsuki]

Three things that horrify me is the idea of being lost on space, being at the bottom of the deep ocean, and being back back in the day. I cannot begin to fathom.

[TheKoppite]

This honestly makes me realise how small we actually are as humans & how all of things that we stress about mean so little…
Because in a instant, if our planet had another drastic change or devastating moment, then we would be the next ones to perish 👀

[diontaedaughtry]

I never thought of the world before the dinosaurs. I'm still trying to understand the Dinosaurs period. This is very interesting and eye opening.

There was 80% of purest oxygen in the air, enough for dragonflies to be the size of present day hawks.

[TimothyOvia]

I am 3 episodes in and already OBSESSED with this channel! Can't wait to watch more!

[Dragon-King]

Fun fact, life existed even before this time in the precambrian era. The precambrian era saw the formation of the earth, moon, ocean and introduced oxygen to the planet making it suitable for life. The end of the precambrian era saw a mass extinction and introduced new life known as the cambrian explosion where evolution started. The cambrian era started around 541 million years ago and ended 485 million years ago

I have to say the ROUS's caught me by surprise. The fire swamp never fails.

[earlosandwich]

The Earth itself was worse than the dinosaurs.

[GiveUrBallsATug]

Do a video on what earth was like before Pangea.

[JMFSpike]

We'll never know what it was truly like back then. Science only gives us somewhat of an idea of what Earth was like back then. What you have to keep in mind is that there had to have been millions of species back then that we haven't discovered and never will discover. If we knew of everything that existed back then, videos and documentaries about those pre-human times would be so very drastically different. And just think, we haven't even discovered all the species that are around today! We're still discovering new species all the time. There are even places on Earth that have either been barely explored, or not explored at all. We also have yet to reach the very bottom of the deepest part of the ocean.

It's funny how smart and advanced that most people think we are. In the grand scheme of things, we're still extremely primitive. This planet is like a tiny fraction of a single grain of sand on the beach, and each of us nearly 8 billion humans individually? We're of no significance at all really, and our live spans are laughably tiny. If you really stop to think about all of that, you'll probably find it hilarious next time you come across a millionaire who thinks he's superior to everyone else. I don't mean this to be depressing by the way, even though it reads that way. The point is to be humble. What most people think is important in life, much of it really isn't at all. Be a good person, be good to the planet so we can remain here for as long as possible, and do good for other people whenever you get the chance.

It's like everything is getting more mellow over the centuries.

[Westiehack]

Props to those people that traveled all the way back in time to film this

At 28 degree celsius, the world felt more like an oven

Tropical zone country residents: Still feels like home
