If brown dwarf Nemesis i real, is Nemesis one of the causes of why that astreoid came to earth

I think that any dinosaur within viewing range of the asteroid probably burst into flames or evaporated, long before impact. Very few of them actually got fossilized.

OH NOOOOOOOOOOOO

I HAD STOCK IN THAT COMPANYYYYYYYY

[ahspupil2007]

They got it all wrong. Chuck Norris farted a tad too strong and the impact was mistaken for an asteroid...

Justin bieber is singing 

[janko008975]

it was chuck norris arrival.. XD ...joke hehe

[OutRoll]

if that meteour didnt hit the Earth the dinosaurs would walk thrugh our streets,towns,villages... FUCKING METEOR

[Bernieo153]

@OutRoll If that meteor did not hit, us humans would never have existed..

[OutRoll]

@OutRoll i know

[stefanoGFsiciliano]

@OutRoll We wouldn't be here if the meteor didn't hit. We wouldn't have evolved.

[DashTheCrow]

Justin bieber's singing killed the dinosaurs

[naterocksable]

@DashTheCrow so true

Amazing that a long time ago, dinosaurs walked the earth, and amazing that nature got rid of them, but yet nature did not destroy its self...

The earth is very powerful and she can endure so much and like magic she can level the ground, destroy, and be able to sustain new life once more :)

[yrmom99]

how did the mamals survive? it says the earths atmosphere was covered in ash, therefor no sunlight would be recieved by plants causing them to die. no plants means no food for animals. they would die of starvation.

[Kittywhiskers1000]

@yrmom99 Yes, and almost all the animals were wiped out as well. Only the smaller animals survived (ones that would not need as much daily intake of energy as a large animal; like the dinosaurs). These animals were mostly opportunists; eating whatever was edible. I'm guessing if the earth was covered in ash for a longer period, life might have been entirely wiped out on land(?). Amphibians and insects weren't hit as badly, so the remaining animals probably lived off them as well.

[MelyssaAKASkittlez]

@yrmom99 Not all the plants died, otherwise there would be no plants left today. The small-bodied animals were able to find enough to eat; the larger ones were not. Those with the largest territories (and largest calorie need) I think starved easiest because they would not bother wasting energy chasing small prey that would not replace the calories used to chase it.

[gethsoftware]

most of the dinosaurs allready had gone extinct bechsoe of an volcanic activity, metheor was just begining of the end.

[StephanSteijger]

Most dinosaurs we killed by the cold after all this.

Lol he's like OSHT THAT WAVES GAININ ON MEH

[340wbymag]

A massive die-off of phytoplankton due to volcanic or tectonic activity, or perhaps due to meteorite impact, reducing the earth's oxygen levels for long periods, and many large animals and plants of that period appear to have been dependent upon an oxygen rich atmosphere. Perhaps the cataclysmic event scientists are seeking was not really all that large, but instead simply impacted a key point in the earth's food chain.

[340wbymag]

@340wbymag Please try to make sense of my poorly worded nonsense above. I was TRYING TO SAY that a smaller event could have triggered a die-off of plankton, and perhaps a huge devestating comet or meteorite may not have been the culprit in the extinctions. Sometimes I thnk we are looking so hard for something BIG that we do not consider the smaller possibilities.

[ctrainbow1]

Great video, love the graphics. I wonder if we will ever know the real Dinosaur Extinction reason.

[taigokai]

I wish i had a tail :(

[mjohanss1975]

@TheCoogieGirls in a way, this is already happening. An extinction level event (ELE) is defined as an event that kills off a massive amount of species. It happens every 50-100 million years or so. The one in the vid happened 65 million years ago so we are due for one now. Mankind, however, has killed more species than the ELE in this vid. So it could be said that perhaps WE are the ELE. Instead of an asteroid happening, WE happened to the Earth.

[ThexRKOx]

i want to be like goku from dragon ball z...

[heartlessvietboy]

If we're searching for answers to why the Dinosaurs went extinct, how come we don't examine what surrounds the rocks that bury the dinosaurs and what type of rocks they are. If we are so good at what we call "carbon dating", examine that.

[poany24]

@heartlessvietboy

The extinction at the end of the Cretaceous era happened around 65 million years ago... Carbon dating is only effective up to about 50,000 years ago.

[heartlessvietboy]

50,000 years and 65 Million years is a big difference. Hopefully one day Carbon Dating (or other dating methods) Technology will improve. C_arbon dating should not be built up as it is to be for now because of the technology.

[poany24]

@heartlessvietboy

Definitely! There's a lot of information to be found if only we could read it. One of the big debates between the dinosaur extinction theorists is the time frame which the extinction occurred. If we could figure out if the extinction happened in a short period of time or over a long span of time we could determine if the extinction was actually caused from one huge catastrophe (meteor impact or volcanism) or from something more gradual (climate change or continental drift).

[heartlessvietboy]

You'd think that things started small then became larger. Then all of a sudden a question comes about what is considered small.  Or how small is small. The same goes with big. What would cause things to become much smaller, including plant life and trees.

[poany24]

@heartlessvietboy

True that. I really hope I'm still around the day it's all revealed.

[sqccccccccc]

@poany24 The problem is that the Cretaceous period was filled with big changes, with two mass extinctions, one in the waters, the other inland.

[MelyssaAKASkittlez]

@heartlessvietboy Carbon dating is useless for dating rock that old.

[heartlessvietboy]

Don't be so confident. Determining age of rock can involve more than carbon dating. We can predict age of layers of rocks/dirt, thus we can categorize rocks by time periods. I'm not an expert in the field, there likely are other methods. To me, its interesting how those "particles" got there and surrounded the dinosaurs. Some are buried in hard rock.

[MelyssaAKASkittlez]

@heartlessvietboy Sorry, I should have specified. Carbon14 dating is useless for rock that old. There may be another carbon isotope that can date rocks that I just don't know about. I do know that radiometric dating of uranium to lead is used in dating extremely old rocks.

[heartlessvietboy]

What's below the dinosaurs are important.  We can examine texture of those particles (dirt). Can you imagine dinosaurs walking on sand?

[MelyssaAKASkittlez]

@heartlessvietboy I can imagine it, but I doubt they would have a good chance of leaving a fossilized footprint. However, I don't think that is what you are talking about, is it?

[heartlessvietboy]

No. Videos don't depict them walking on desert sand. The Desert is far, dry and open. Lots of lizards live on sand.

[MelyssaAKASkittlez]

@heartlessvietboy I saw that. In Walking with Dinosaurs, a Eustreptospondylus was walking along the beach looking for food...then all of a sudden a huge Liopleurodon lifts its head out of the water and snatches it by the tail. A lone Pyroraptor in the the Dinosaur Planet episode called Pod's Travels was washed away to an island by a huge wave and he walked along the beach until he regained his strength and senses and traveled inland. Don't know of many that stayed on sand long.

[ForDoverUSA]

dinosaurs never existed. It's all story telling. JK, but really, has anyone seen em?

[freacls]

@ForDoverUSA yep i have a huge T rex called Barney lol

[lukebccb]

Does this have anything to do with me masturbating to online porn?

[livi334]

@skatethenskate yeah, lol

[bannash123]

i see a lot of videos that reinact the asteroid hitting earth and every one so far has not shown the earth in pangaea.

[sounza]

great video and which one is 100 % true

[Bristow42]

Doesn't add up, the reason animals evolved to fit to climate and habitat. Which means animals trying to fit into blank spaces have to evolve faster that the surviors already in those spaces. And as the climate to a new one, I would say it was climate change.

[chintwins1]

@Bristow42 I agree though I think there was a small volcanic erruption or medeor shower that contributed. The dinasaurs were already in decline I think a mass climate change was the last straw.

[MelyssaAKASkittlez]

@chintwins1 I believe the volcanic eruption was a flood basalt. They can last for a million years and spew copius amounts of greenhouse gases into the environment, as well as release toxic compounds in the eruption area. That would have lead to some degree of climate change. You are right, close to the KT boundary the dino fossil record becomes more sparce.

[t0k3puff420]

worst day ever!!! :(

[freacls]

@t0k3puff420 yeah its sad about the Dinosaurs dying but maybe its for the best if they ere alive today where would they live i cant imagin them running through the city streets and i dont think any zoos would keep the big flesh eaters maybe the brontosaurus would be in a zoo but the rest of them i dont know and theyd be hunted by humans

[iambored678]

wowh:O
