New Theory! Did THIS Kill the Dinosaurs?

New Theory! Did THIS Kill the Dinosaurs?

“It may not have been climate change or an asteroid or depleted resources that eliminated the dinosaurs. It could have been two ticking geological time bombs - that are still with us today.

United Press International reports that a controversial new theory holds that several of Earth's largest extinctions, including that of the dinosaurs, were due to massive eruptions of lava that are linked to two extremely hot blobs of mantle some 1,700 miles beneath Earth's crust. These sizzling hot blobs were formed about 4.5 billion years ago.

When a huge amount of magma bursts through the Earth's crust, which has happened periodically, it forms oceans of sizzling lava that flood some 40,000 square miles and not only poison the atmosphere, but also entire groups of animals.

When such an event occurs, it creates a distinct geological region, known as large igneous provinces or LIPs. One of these was formed when the dinosaurs became extinct.

"There is an amazing correlation between mass extinctions and LIPs," Andrew Kerr at the University of Cardiff told UPI.

In addition, Matthew Jackson at Boston University and his colleagues say they've found evidence that LIPs are fed by 4.5-billion-year-old stores of mantle. Jackson's team found 62-million-year-old basalts from the North Atlantic LIP contain isotopes of elements in ratios that reflect the chemistry of early Earth's mantle, reports UPI.

And two of those magma blobs are still there - one beneath Africa and the other beneath the Pacific Ocean.

"It's an interesting idea - that a giant blob of hot magma might burp from near Earth's core every now and then, causing havoc for life," says Gerta Keller at Princeton University.

……

If there are layers of hot magma stored beneath the earth’s surface that could erupt at any time and spew oceans of sizzling hot lava over 42,000 square miles killing anything in it’s path, we need to take another look at our mining, drilling and ‘fracking’ as to the possible effects it may have concerning this hot magma stored beneath the Earth’s crust.

In the area of fracking alone there have been many earthquakes associated with the high pressure type of drilling for gas and oil in the ground. Questions of contaminating the ground water, and the environment are of great concern to townspeople. Although the mining companies say there is no health problems connected to ‘fracking,’ the incidence of earthquakes in surrounding areas of mining shows that high pressure fracking does seriously interrupt the stability and quality of underground soil and water.

‘Fracking’ is injecting millions of gallons of fracking water, sand and chemicals under high pressure into the drilling well. This process breaks up rock formations which allows gas and oil to rise thru the drilled well. To avoid collapse of these fissures, sand is also forced into them.

Fracking fluid may contain the following chemicals: organic compounds including ethylbenzene, glycol-ethers, xylene, benzene, methane and toluene, and nonylphenols. These substances are quite harmful, especially when they get into ground water and risk contamination of drinking water used by individuals, as well as agricultural and industrial processes. Research also shows that long-term usage of water contaminated by ‘fracking’ fluid and fracking sand may lead to serious and life-threatening disease.

If we are to ensure against another earth shattering event that killed off an entire species of dinosaurs, we must ensure the safety and stability of the earth’s interior and crust, underground water quality, the environment, and the quality of life for its people.

 

it's unlikely that there was ever any real mass extinction event that killed off the dinosaurs. mass death leaves mass graves, and there just aren't any of the dinosaurs that formed herds. they died off slowly, not from a single event. even if the earth suddenly froze, the herds would have stayed together.

 

One of the biggest mass extinction events occurred 250M years ago. Siberail was one large volcanic caldera, contributing CO2 and heat for about 5 degrees F. The oceans slowly warmed until some of the methane ice started melting, creating positive feedback, melting more until something like 2000 gigatons entered the atmosphere - 95% die off.

There is speculation that an asteroid hit the plaent on the far side of Siberia, creating that caldera.

Of course, when Yellowstone erupts as a super volcano, the planet will cool, most crops will fail. People will eat just about anything organic, wars will erupt.

The last two people will probably kill each other while arguing about MMGW.

 

Here's a short film on FRACKING

Actually I've read about this before.

Most scientists accept a possible "double whammy" the comet hit, and then the magma came, the comet could have conceivably set it off and between the two.. no more dinosaurs in a few decades.

 

Who knows?

 

so what about the iridium layer?

http://en.wikipedia.org/wiki/K–T_boundary

but even so, I figure there would be a few things that might spark off something - including impacts, human activity, or possibly some other geological event ...

we can't control for natural events (yet) but I think we need to think about what we do.

with the technology we have today, we could be a bit like a kid who doesn't know his own strength.

 

source please ?

as far as I know there are 4 theories of the Permian extinction none of which involve asteroids

• glaciation of the Gondwana continent
  
• reduction of shallow continental shelves due to the formation of the super-continent Pangea
  
• rapid warming and severe climatic fluctuations produced by concurrent glaciation events on the north and south poles
  
• basaltic lava eruptions in Siberia and the combination of sulphates in the atmosphere and the ejection of ash clouds may have lowered global climatic temperatures

there were also mass extinction events during the Precambrian, Vendian, Cambrian, Ordovician, Devonian, Permian, Cretaceous and Holocene. All of which had 1 thing in common, they are all events which involved the cooling of the planet. In the Geologic timeline we are in a period of cooling and have a CO2 deficiency.

I don't think there is much argument over whether climate changes, the argument is over how much effect Co2 plays in it. Nice to see some people here are starting to realize that the last 10K years was noting more than a gnats blink in the timeline

 

You hit the Earth with a large enough asteroid and you get eruptions.

 

Uncle Ferd says it was due to aliens...

... dey ran outta meat on their planet...

... so dey came here an' gobbled up alla dinosaurs...

... kinda Alpha Centauri's version of Thanksgiving.

 

I just have to ask Americans "How the hell there can be so many scientifically ignorant people in one society" There are bloody taxi drivers here who have more knowledge about science - and THEY came from poverty stricken areas of India

Google is your friend......

counter-point. http://www.bbc.co.uk/sn/tvradio/programmes/horizon/dino_prog_summary.shtml

and for bonus points, it's on topic.

 

That is about the CAUSE of the extinction events - not a questioning of whether or not they actually occurred. There is little doubt that the mass extinction events were sudden events because we basically have one large mass grave to explain away

 

mass of graves is not the same as mass graves.

mass of graves-



mass grave-

 

But my question is how did mammals survive this? The comet and climate change explains why mammals would survive because they were better suited for harsh cold. But they aren't better suited for lava.

 

the real problem wouldn't be the actual lava, it would be the poison spewing into the atmosphere. as i recall, volcanic fumes are heavier than air, so they would settle in the lowlands where bigger animals live, and it would only take a few colonies of small furries in the mountains to out live them as a species.

The asteroid theory is out there if you look.

 

ah okay that makes sense.

 

It is because bigots from other societies are typically prone to judge all of us on one post.

There is also the Robert T. Bakker hypothesis of disease playing some part in it. Disease might be likely in event of changes in behavior and other things due to climate change, and with disease herds although dying in a mass extinction might not all die at once in a mass grave. So if there was no mass grave, then there easily is a hypothesis to account for it.

Is it "scientifically ignorant" to say, "birds are dinosaurs?"

If they are related then "it's unlikely that there was ever any real mass extinction event that killed off the dinosaurs." If any of their family tree survived at all, dinosaurs were not killed off.

 

I thought you might have something recent. Those theories were debunked a couple of years ago as referenced by a link above. The Yucatan asteroid was 300K too early, although I heard some people are trying to revive the asteroid theory no one has been able to disprove Keller yet as far as I know

http://earthsky.org/biodiversity/did-volcanoes-kill-the-dinosaurs

Keller leans toward Indian peninsula volcanic activity

Journalists need to learn the difference between a hypothesis, a theory and a fact. All the hypothesis of dinosaur extinction are just that, none even can be considered a theory

you want to look into soemthing more recent then do some research on the freshwater forcing of the Younger Dryas and all of the contradictory evidence now of that hypothesis being brought forth. On a aside it was once thought Younger Dryas was a meteoric impact event also

 

there are advantages to being small, and animals that were small (including some mammals - and some dinosaurs) were more likely to survive, whether through finding smaller safe places, scavenging, having a shorter life cycle and therefore having the chance to evolve more rapidly in response tot he stresses in the environment .....

you don't think its likely any dinosaurs survived?

this might interest you:

But they are better at dodging rocks from eruptions lola

Anyways this is the REAL reason why the Dinosaurs became extinct

 

((((((((((sobs))))))))))))) Science education - why do people not think it is important??

 

It's been proven that a meteor did not kill off the dinosaurs, at least not nearly how it's portrayed. I wasn't the main killer at all. It's why there isn't a mass of fossils at the KT boundary. In fact you'll be hard pressed to find any.

 

Find Iridium in so many places does suggest that it might have been an asteroid/comet
