"Give or take a few years" recalls Helen Thomas.

[allmendream]

700,000 years is 70% of one million.

When talking about 64-67 million years ago, less than a single million is an “error” of less than 1.5%.

Not sure how confident I would have to be about the tolerance range of such numbers before going to publication, but that is just me.

Did make the news though..... rather weak sauce if you ask me.

[GeronL]

Obviously they will need to revise their theories. It wasn’t not uniform around the world obviously

“this particular plant eater was alive about 700,000 years after the mass extinction event many paleontologists believe wiped all non-avian dinosaurs off the face of earth, forever.”

But he was reeeeeaaal lonesome...

Colonel, USAFR

[cripplecreek]

Bob Bakker is right. The “mass” extinction was really a major extinction event amid a long slow decline.

[Snickering Hound]

There goes THAT theory...

[qam1]

These dinos lasted 700,000 years past the supposed K-T event

All other dinos died 300,000 years before the supposed event

Birds, Sea Turtles, Alligators + Crocodiles, All Freshwater species, Honeybees and Photo-plankton lived through the supposed K-T event as if nothing happened (Even though they would be the organisms that should have been the 1st to go).

It's looking more & more that the K-T event was a non-event

Yes I know, An asteroid falling out of the sky and killing the big bad dinos sounds really, really cool, but sorry the evidence shows it just didn't happen.

[muawiyah]

Alternatively the fellows who kept track of the dinosaur parks on Earth came around to do a survey and found all their animals had been killed ~ so, being good stewards, they brought in some newbies!

They came back 32.785 million years later on their regularly scheduled rounds only to find that LOCAL FAUNA had taken over and eaten all their hadrasaurs. They got so upset they nuked half the new animals.

Test shows dinosaurs survived mass extinction by 700,000 years

[PA Engineer]

On history (I forget the professors name) an anthropologist from Austin provided compelling evidence for extinction by disease. The Anthropologist asked where are the "bones" in the "K-T Boundary"? The answer of course is there are none. Science Daily has a decent article on this theory.

[Mayr Fortuna]

well... It is amazing...

Theories are theories... Somehow in the late 30 years or so, theories have got Law Status...

Nobody see a theory as it is anymore, mainly the media...

[Mayr Fortuna]

I must say more on this...

Only if PROVED a theory is useful... Things like Global Warming should never lead to actions, unless PROVED.

Many more samples of theories are being used to control not only human behavior, but human live broadly...

"Heaman and colleagues used a new INdirect-dating method called U-Pb (uranium-lead) dating."

Fixed it.

Assumptions

• Living bone contains very low levels of uranium
• but during fossilization (typically less than 1000 years after death) bone is enriched in elements like uranium.
• The uranium atoms in bone decay spontaneously to lead over time and
• once fossilization is complete the uranium-lead clock starts ticking.

Nonstated assumptions include:

• Uranium enrichment only occurs during fossilization.
• Fossilization occurs only in a short amount of time and is not a continual process.
• decay rates have been uniform over time.
• Beginning lead rates are also assumed, probably at 0.
• No groundwater contamination with uranium or lead except during the fossilation period.
• No groundwater leaching of uranium or lead.

[BenLurkin]

Yet another example of why people shouldn't take “science” too seriously.

[The Comedian]

700,000 years my carbon married (gave up dating) behind.

I call BS. We know now that radioactive decay is not a constant, and seems to be influenced by solar cycles. I'll bet these fluctuations in the isotopic decay rates aren't figured into the age estimate. In fact, I don't think they can be, because we just discovered the effect and have no idea how long or broad it is.

Today is a good day to die.
I didn't say for whom.

[Mike Darancette]

Now they have retest all the previous findings if all that has changed is the dating method.
