What happened to the Dinosaurs?
I am somewhat surprised that there has not been a discussion about this.
Have you ever contemplated what the hell happened ~65 million years ago that caused the dinosaurs to lose control, and eventually die off completely, of the planet that we now control? What do you think happened?
What would Earth be like if that comet/asteroid had not hit our planet ~65 million years ago? (This is widely accepted as the moment when dinosaurs began to lose control of the Earth)
The dinosaurs would have certainly continued to evolve, but how? Would something that looked like a dinosaur be staring at a computer right now, instead of you?
Please share your thoughts on the history of Earth. What are your beliefs? Are you interested in learning more about it? There is a lot to learn
The earth is fucking old! And its history is pretty awesome
They never existed.
Meteors / Mass flood would be the best guess.
@lolivia, that was pretty deep
A comet or asteroid is one idea, or a super volcano. There is also the idea that all the herbivoures ate all their food supply and starved, with them gone all the carnivoures ate each other. Also the big time ice age is another theory and it is not a case of them being cold blooded, because a lot of academics are unsure of that lately, but because they were so big their hearts could not handle the strain the cold put on their large bodies.
They evolved into birds.
The chances of a comet or an asteroid hitting Earth are fairly astronomical. Between Mars and Jupiter there is a huge asteroid belt, hundreds of thousands, maybe millions of asteroids. You would think that increases our chances of being hit by one but that the belt, like a planet, has a gravitational well. This gravitational well draws back to it any stray asteroids, say if two big ones collide in the belt, one may be sent toward Earth but the gravitation of the belt is so strong, it will most likely be drawn back.
I thought this was somewhat solved among scientists. While exploring these cave wells in the Yucatan Peninsula, geologists started mapping them out and discovered that they formed a massive, near perfectly geometric circle around the area. They speculated that this was the residue of an impact crater from a GIANT comet. Idk if they’re sure how exactly this killed them. Typical theories suggest that a massive dust cloud covered the earth and most vegetation died off, and a mass extinction followed. I heard one about it creating a monolithic hurricane ( a “hypercane”) that triggered terrible weather and climate patterns.
@cooper2023, Yes, I heard about that, I seen a doco on it, that no doubt could have been it. But there is no way it could have been a direct hit by a full comet, as I just explained is much more likely, simply because the size and speed of your typical comet would have been an Earth destroyer, there wouldn’t even be life now, there wouldn’t be much of a planet to speak of. So a shattered piece of comet is my bet.
@trek79, “The odds of a comet or an asteroid hitting the Earth are fairly astronomical.”
OH YOU DON’T SAY
@danfontaine, You see what I did there?
@trek79, Ray, have you ever seen the Star Trek: Voyager episode where the crew of Voyager meets a spacefaring race that turned out to have evolved from Earth dinosaurs?
@theskafish, yes I have indeedy. What is interesting about that episode is that it show you can tell if any two life forms, no matter how different they may be, you can tell if they came from the same planet by examining their genetics, dna and stuff. There are markers that a human has in common with a slug that can tell a geneticist that we are from the same planet. That is some awesome shit, that episode. I was even thinking of bringing it up, cheers.
