Test shows dinosaurs survived mass extinction by 700,000 years

I fail to see the importance of this. I am nearly 68 years old. I will probably live into my 80's.

So something that lived 64.5 million years ago just isn't relavant to my survival or really needed in my sphere of relavant knowledge.

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.

Um. Wow.

[PA Engineer]

Wow. You have a bad case of hiccups! ;-)

[OB1kNOb]

We get the picture. ;-)

Have you any opinion on the relevance of this?

I wonder a member’s posting history includes duplic.... triplica.... uhm... triskadecaplate posts?

(I just made that up off of the word for fear of the number 13)

Set the coffee down and back away from the computer...

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...

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.

Food chain disruption can selectively eliminate species. An asteroid has the capability of doing that.

Ahhhhhhhhhhhhhhh!

There were a couple of multiple replies last week and another day some time ago. All three had 16 replies.

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...

I would say there was a malfunction on the system or between the system and the network...multiple resends from the modem maybe!!!

Is your gear New or Old?

"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.

You think that is something, look what I found. Old thread. Check the first 200 or so.
