Fossils show worldwide catastrophe on the day the dinosaurs died

Sixty-six million years ago, a massive asteroid crashed into a shallow sea near Mexico. The impact carved out a 90-mile-wide crater and flung mountains of earth into space. Earthbound debris fell to the planet in droplets of molten rock and glass.

Ancient fish caught glass blobs in their gills as they swam, gape-mouthed, beneath the strange rain. Large, sloshing waves threw animals onto dry land, then more waves buried them in silt. Scientists working in North Dakota recently dug up fossils of these fish: They died within the first minutes or hours after the asteroid hit, according to a paper published Friday in Proceedings of the National Academy of Sciences, a discovery that has sparked tremendous excitement among paleontologists.

“You’re going back to the day that the dinosaurs died,” said Timothy Bralower, a Pennsylvania State University paleoceanographer who is studying the impact crater and was not involved with this work. “That’s what this is. This is the day the dinosaurs died.”

About 3 in 4 species perished in what is called the Cretaceous-Paleogene extinction, also known as the K-Pg event or K-T extinction. The killer asteroid most famously claimed the dinosaurs. But the T. rex and the triceratops were joined by hordes of other living things. Freshwater and marine creatures were victims, as were plants and microorganisms, including 93 percent of plankton. (A lone branch of dinosaurs, the birds, lives on.)

If you’re stupid enough to believe in creationism, you’re stupid enough to believe Dump...and you are wasting good oxygen.

Would the world now be a better place?

No humans, no Hitler, no Repukes and No Dump.

But maybe we’ll get something better a few million years after the next one.

One of the upsides is a recharge of geothermal energy from newly generated molten rock from a really big crust-shattering impact right into the mantle.

Maybe we’ll even have another moon, as long as it doesn’t make the weather too ridiculously chaotic. A different axial tilt might be nice.
