Dinosaur extinction: roasted alive at 800 ° C




by Christophe » 27/12/10, 23:30

A new detailed theory about the brutal extinction of dinosaurs (and almost all "aerial land" life 65 million years ago) particularly appeals to me: a 24-hour planetary barbecue consecutive to the impact of an NEO.

We think we know certain things, but when we look more closely, we realize that there is still a lot to learn ... 65 million years ago, a gigantic asteroid, as large as a large modern city and more as large as the Himalayas, headed for Earth at full speed. When it hit it with the full force, it not only wiped out all of the dinosaurs, which had reigned supreme for hundreds of millions of years, but it also destroyed three quarters of all life on our planet. This is what we think we know. But the rest? ...

What happened in the first seconds, the first minutes, the first hours after the terrible collision? Why were some creatures able to survive, and give birth to a progeny which ultimately resulted in man, when at the same time almost all the other species perished? And what would happen if a new disaster of this magnitude loomed on the horizon?

To answer all these questions, and understand all the phenomena at work in these types of circumstances, scientists from NASA have embarked on astonishing research. By descending on the ground and using cutting-edge technologies, their goal is to succeed in recreating the conditions of the catastrophic impact that changed the world forever. And, by examining it closely, to be able to accurately determine the extraordinary cascade of events that occurred 65 million years ago (shock wave, earthquakes, mega-tsunamis, planetary fires) . Who has won in this chain reaction? Who lost and especially why?

We are living proof (this is the case…) that there have been survivors of the most mind-boggling cataclysm in Earth's history. Could we escape hell again if it happened again? Statistically, the question is not, moreover, whether such an impact could occur again, because there is no doubt about it, but when ...

800 ° C certainly not because there is no trace of general carbonization dating from this time, except near the impact, which must be remembered was 3/4 marine, the vaporization of marine waters having limited the elevation of t ° at 180 ° C for a short time according to the latest estimates ... The lower atmosphere would have been fairly quickly rid of dust due to intense precipitation ... If this had not been the case no terrestrial animal would have survived for lack of habitat and food ... knowing that small mammals require a very important food supply compared to their mass because of a very fast metabolism ...

oiseautempete first watches the video and we discuss it ... they speak well of 800 ° C ... Precisely, these 800 ° C did not come directly from the impact but from the fallout from the debris of the impact. If you look, you will understand. 8)

Thank you for the link of the full video, I had yet searched ... pfff ...
Another link that points to the full video: http://www.rtbf.be/video/v_matiere-gris ... iepratique

Not obvious their site ... I had found the whole of the one on stress which is passed in "extract" it seems that on RTBF.be, they change their policy like a mouse ... :| :|

https://www.econologie.com/forums/le-stress- ... 10067.html

I do not understand these limitations: a program already broadcast should be available all the time on official sites (FR TV, Arte ...) ... it would cost them little (storage and bandwidth) and everything could be funded by advertising (good except on arte where there is no advertising, European funding ...)

Their leaders should look at the "Youtube" business model ... especially since at the same time they are doing this: https://www.econologie.com/forums/films-comp ... 10268.html ??

I am afraid that the video is not visible in France.

I did not understand everything there, if this hypothesis was correct, how to explain that species recognized as belonging to the clade of dinosaurs like birds could have survived, they who were particularly vulnerable while evolving in an atmosphere which had become apparently lethal. .

Since it would be the same one that would have suffered the other non-volatile species that would have become extinct? So the birds should have disappeared first, right?

Besides, if from certain points of view, this theory meets the other: either that a difference in temperature would have knocked them down following the explanation of this sudden peak, the birds should not have survived either, precisely for this reason?

So I'm rushing : Mrgreen:

The report explains that the survivors were those who buried themselves and who were small enough not to need too much food during a long enough period of "regeneration" ... knowing that the carcasses of the barbecue constituted a food reserve. interesting.

Given the biodiversity of the time, it's a safe bet that there were birds that knew how to bury themselves ...

The underwater species also mostly survived the giant bbq ... but the nuclear winter that followed is another matter ...

So I still don't know if this is the theory

Well in this area, there are almost as many theories as there are research teams ... : Mrgreen: : Mrgreen:
