They worked in volcanic eruptions and global warming as the cause (preposterous), those interested should read the original.

“about 252 million years ago.” Exactly? So they really don’t know and it is pure speculation.

You misunderstand what the meaning of the phrase ‘pure speculation’ is. This is the exact opposite.

One degree celsius equals 1.8 degrees Fahrenheit. So 20 degrees celsius equals 36 degrees Fahrenheit. Add that to any temperature and you have serious ecological problems.

Outcrop photos of the Permian-Triassic boundary interval at Penglaitan. You can see the layer of plastic straws which caused the Great Dying.

What ever caused the Siberian Traps to be formed occurred around the same period as the Permian extinction.

Particularly if the temperature change is from a large impact, a la Chicxulub. The entire atmosphere went up suddenly, as in 90 minutes or so throughtout the world's surface.

Radiometric dating on the Traps has tightened down to about 7 million years, but if anything, the P-T extinction and the traps had a common causative event -- obviously an impact. It's not unlikely that the most likely candidate for the impact site *is* the Siberian Traps, which slowly covered over the astrobleme.

Never address the topic, or exhibit any interest in science or history, just regurgitate your same old tired BS.

“...a single bed of volcanic ash-rich sandstone...”
Could be a clue in there.

Yes, because God put the fossils in the flat eart 6,000 years ago. Just to throw us off.
To: SunkenCiv
"the most likely candidate for the impact site *is* the Siberian Traps" One of the arguments I've heard for the P-T extinction not being caused by an impact is the lack of an iridium layer, similar to the one found for the Cretaceous extinction. I've also heard that the Permian extinctions appear to have occurred over a long period of time, rather than being a swift die-off.

Well, the excerpt posted here says 10°C or 18°F but that is still a lot. And the way I read it, it appears that this temperature rise occurred immediately AFTER the extinction event and thus is not proposed as the cause.
To: Fungi
about 252 million years ago. Exactly? So they really dont know and it is pure speculation. Dating something to 3 significant digits is "speculation"?
