I lost the URL for a great Japanese animation of a planet-killer striking the earth. Very high quality and, somehow, calming. If the Big One hits, I won’t even feel a thing.

Who was it the PREDICTED the size of the asteroid which killed the dinosaurs? That must have been some trick.

Chemostratigraphic Evidence of Deccan Volcanism from the Marine Osmium Isotope Record

Science 21 November 2003:
Vol. 302. no. 5649, pp. 1392 - 1395
DOI: 10.1126/science.1089209

Continental flood basalt (CFB) volcanism is hypothesized to have played a causative role in global climate change and mass extinctions. Uncertainties associated with radiometric dating preclude a clear chronological assessment of the environmental consequences of CFB volcanism. Our results document a 25% decline in the marine 187Os/188Os record that predates the Cretaceous-Tertiary boundary (KTB) and coincides with late Maastrichtian warming. We argue that this decline provides a chemostratigraphic marker of Deccan volcanism and thus constitutes compelling evidence that the main environmental consequence of Deccan volcanism was a transient global warming event of 3° to 5°C that is fully resolved from the KTB mass extinction.

So this asteroid caused Osmium levels to decrease thousands/millions of years before it actually hit??

LOL! These Asteroid people with their computer models and evidence cherry picking are almost as bad as the Global Warming Religionist

"That's the finding of a new technique being developed to estimate the size of ancient impactors that left little or no remaining physical evidence of themselves after they collided with Earth.

How convenient, theoretical "impactors" that conveniently vanish leaving no trace they ever hit the earth, and killed all those dinosaurs.Must be true however, because they said so.

Scientists working on the technique used chemical signatures in seawater and ocean sediments to study the dino-killing impact that occurred at the end of the Cretaceous period, about 65 million years ago.

Great. This ones even better. Chemical signatures from things that may or may not have existed, but left no evidence of being there so one can't say either way. But somehow, the KNOW just what chemical signatures they lefty behind, even though they can't tell you what it was made of, snow, rock, frozen methane?

One thing we know,(because they say so) these impacts made all the dinosaurs fall into what are now the saudi oil fields and other large oil fields arounfd the earth.

500 billion of them fell in just in ONE Saudi oil field. There sure were a lot of dinosaurs on the earth when that invisible meteor hit. Zillions of them.

These guys make a living by coming up with new theories — it's best not to take any of these “scientific” theories too seriously.
