Summary : Paleontologists have found a fossil site in North Dakota that contains animals and plants killed and buried within an hour of the meteor impact that killed the dinosaurs 66 million years ago. This is the richest K-T boundary site ever found, incorporating insects, fish, mammals, dinosaurs and plants living at the end of the Cretaceous, mixed with tektites and rock created and scattered by the impact. The find shows that dinosaurs survived until the impact.

That is a fascinating article. Bless you.
I tend to lean towards a blend of the various theories. Environmental changes (the Siberian Traps kicking up their heels) caused the dinosaurs to decline and then the K-T sealed the deal so to speak.
Well other then birds who are basically dinosaurs devoted to pooping on our cars.
I suspect an overall drop in global temperature from both events killed off the large dinosaurs, the pterosaurs, and the large marine reptiles. Which left the door open for sharks, crocodiles, birds, and mammals to all have their day in the sun so to speak.

There was no "meteor impact" that killed the dinos. It has been proven that the so called meteor that hit the gulf was in fact a volcano under ground, just like the Yellowstone volcano. Dinos did not die 66 millions ago.

I'm no scientist, but these Paleontologists seem pretty sure about this :
In a paper to appear next week in the journal Proceedings of the National Academy of Sciences, he and his American and European colleagues, including two University of California, Berkeley, geologists, describe the site, dubbed Tanis, and the evidence connecting it with the asteroid or comet strike off Mexico's Yucatan Peninsula 66 million years ago. That impact created a huge crater, called Chicxulub, in the ocean floor and sent vaporized rock and cubic miles of asteroid dust into the atmosphere. The cloud eventually enveloped Earth, setting the stage for Earth's last mass extinction.
"It's like a museum of the end of the Cretaceous in a layer a meter-and-a-half thick," said Mark Richards, a UC Berkeley professor emeritus of earth and planetary science who is now provost and professor of earth and space sciences at the University of Washington.

It's both me and SOS. Everywhere. They even follow us to the recruiting board. Like fricking clockwork.

It’s true. How could a meteor hit earth 66 million years ago when the Earth is only ~6000 years old?

Great find. 
Proves beyond doubt that dinosaurs were extant at the time of the impact. The discovery will grow in importance as the site is excavated and its contents are analyzed. There may well be soft tissues preserved because of the immediate burial of the animals by the seiches.
That no human artifacts were found is telling, too.
