That's the beauty of science.
The "Dinos were killed by asteroid hypothesis" was very shakey to begin with.
An asteroid came out of the sky and killed all the dinosaurs but somehow left other things like Alligators, Parrots, honeybee, tropical frogs, sea turtles and many other temperature sensitive animals that you would expect to be the 1st to go, seemingly unaffected should have at least had people scratching their heads.
The good news is this hurts liberals more, the only reason this hypothesis got as far as it did was because of it's anti-nuclear weapon implications(Well and the coolness factor)
I knew it, I knew it...Dinosaurs were living 6000 years ago!
There have been some speculations that the shockwave propagating from the Chicxulub impact may have triggered volcanic eruptions on the other side of the world in India
Something did go extinct, the asteroid predictors who were wrong.
...no other large craters are known to have caused a significant extinction event.
No significant extinction events known to have been caused by other large craters? Interesting. Still, it's probably a good idea to keep a wary eye on those large craters...they could turn into killers at any moment.
This researcher has been on a crusade to disprove the asteroid impact theory and won’t share her evidence when asked so this should be viewed as a personal vendetta or something of the like.
I've got to admit, tho, that between my eighteenth and twenty-fifth birthdays he did a lot of evolving.
300,000 years is still only the blink of an eye geologically speaking. So, the mass extinction took more than a few years, or a few hundred. It was still very rapid.
The impact theory will have to do until proof of something else is discovered.
To read later.
Being that the Deccan traps started to erupt 5 million years before the "supposed" asteroid hit that would be a good trick.
But I heard the opposite, that the Deccan traps could have caused what's know as a geobleme and that's what Chicxulub could be.
>>However, a number of scientists have since disagreed with this interpretation.<<
They are just a bunch of deniers.
Haven’t they heard, “the debate is over”.
Even if it didn’t kill the dinosaurs, I am sorry....it killed something.
You CAN’T tell me with a straight face that a 100-mile wide crater didn’t kill at least one entire species.
Yet this chucklehead actually is trying to claim that. I could buy the time issue with the dinos, but not that.
Nobody else has said anything like that. This nut is out there by himself.
lol...
I still don’t believe the premise that no major extinction events have occurred due to the space rocks causing those big craters.
I thought they all died from smoking.
I don’t think the report is saying that there were no mass deaths, just not a mass extinction of a entire species.
It is sad for those people to waste good brainpower and often a career to find out everything they’ve written and promoted is discovered to be false. But these fields are so full of hypothesis and guessing it’s really hard to consider them hard science like nuclear physics or chemistry. There’s always so many “may have”, “could”, “might”, “we think”, “it suggests”, in these kinds of areas it is kind of ridiculous to take anything anyone says about anything as ‘gospel’ (no pun intended).
Accordng to the EPA they may have all died from being alive (CO2).
Maybe they didn't die out right away, but started to decline with the decline in air quality after the asteroid strike.
Yeah, but hundreds of thousands of years? I'd think...ahem...the dust would have settled long before that.
I admit it sounds like a long time. As I typed, I had the tongue-in-cheek analogy in mind about degradation of the current environment probably not leading to immediate problems, but to doom in the future. Like those dinosaurs.
Don't forget to notice the "sarc" in my sig!
