This graphic shows historical variations of Mercury (Hg) deposition before and after the Latest Permian Extinction event as recorded in a sedimentary section in the High Arctic, Canada. The vertical axis demonstrates the depth of the sedimentary section relative to the extinction boundary while the horizontal looks at the amount of mercury accumulation (concentration in the rock) as measured in milligram per kilogram.

"No one had ever looked to see if mercury was a potential culprit."

Would traces of Mercury be detectable in Dinosaur bones affected by the event?

I’m surprised someone hasn’t blamed volcanos on CO2, mercury, or some other natural product.
Personally, I think liberals cause volcanos. Now what can we do to eradicate liberals? It’s already proven that liberals are a danger to society.

Global warming is going to cause mercury to rise. Eventually thermometers will burst all over the world and mankind will become extinct if we don't act now to give climate scientists control over the world.

Volcanic activity never was and is not now the greatest source of mercury in earth's ecosystem.

Volcanic activity as a source of mercury runs a really, really, distant second to sub-sea erosion.

Both are, of course, exponentially greater sources than the burning of coal.

Recent studies supported by the Ford foundation and Recyclers University suggest that Mercurys became extinct dinosaurs as they couldn't adapt to gases in the sales climate.
As the volcano of cars sales slowed and the atmosphere for economic activity became poisonous academia flourished under the glacier weight of useless studies about the value of hybrid auto design.
Today having gas is the common legacy of these speculations about digestive upsets, also known as BMW, and CAFE.

All nonexistent information here has been verified by Chokem, Hokem and Fiat.

Damn Mercury's

Women and minorities hurt the most.

It’s because they were cold-blooded. The destroyed all those useless thermometers and all hell broke loose.

What IF?

250 million years ago....

What if an animal back then evolved intellegence and then built cities and drove SUV and was the cause of all the extinctions including themselves....

I am sure we just need to looks for fossilized SUVs and out of place artifacts....

I have a sketch here of what they could have looked like...

I want some grant money to search for this.
