The top six dinosaur myths and how we busted them

Myth 6: Dinosaurs all became extinct

The asteroid wiped out the dinosaurs, almost. T. rex, Triceratops and the rest disappeared, but a handful of small feathered dinosaurs, probably less than a dozen species, survived. They were birds — small, flying cousins of T. rex and Velociraptor and the direct descendants of the carnivorous dinosaurs. And they not only survived but thrived, evolving into some ten thousand species of birds.

When I was a kid the connection hadn't been made yet, so people could say the dinos died out and the books supported them. Now we know the books were wrong, but no deliberately so, just to the extent of the knowledge they had at the time.

Too bad some people aren't updating their Book as new knowledge becomes available.

I never understood how all the dinosaurs could be killed by one asteroid unless they hadn't spread out very far. The one's that weren't killed by the asteroid would not have been fossilized. They would have died some other way.

I's really remarkable that we have such a rich fossil record when you consider that most animals don't die in a way that allows their remains to be preserved in tact.

The "nuclear winter" (perpetual overcast and resulting cold weather) from the Chicxulub meteor killed off the plant life. The herbivores died because of that. The carnivores turned scavenger and finally ran out of food themselves. The small critters could find bits of food to sustain them here and there, but complex life was tittering on the abyss for a while. 

As for fossils, there may be more than we think. Lee Berger found two sites with numerous hominid fossils, in 2008 and 2014. We're talking thousands of bones. He mentioned that you can find many thousands of antelope fossils in the area (near Johannesburg, South Africa.) So it may not be so remarkable after all. The T. Rex "Sue" was found in a nearly complete state.

Nearly everything was killed, it was an extinction event.  It's a bit of a simplification to say that everything got wiped out by an impact.  More the lasting effect of that impact (and other contributing factors not related, specifically, to any impact event).  Straw that broke the camels back kind of thing.

The damage to the biosphere, planet wide, was considerable.

IIRC, upwards of 1% of the atmosphere was lost to space as the impact energy was far in excess of the Teller maximum.

It was an enormously devastating blast.

{edit, went and checked Wiki}

Long high splashes of molten rock were also blasted into space and created intense heat around the globe when they re-entered the atmosphere.  The blast also triggered earthquakes and volcanoes planetwide.

I doubt everything got wiped out. some things had to survive, or we would not be here. New life could not have developed on earth after the oxygenation event, so if everything got wiped out, that would be it.

Hey, couldn't scientists easily recreate the beginning of life on earth in a controlled environment? Don't we know all the necessary conditions? A Christian controlled senate wouldn't pay for it, but fuck that. If it can be done, I'd give my last dollar to see it happen.

You know what this means, don't you? The second coming came at the end of the Jurassic age. The dinosaurs were eating and drinking and buying and selling, then sudden destruction BOOM!

I thought the dinosaurs were gay and god smote them
