Well, there's a lot of meat on them critters. If they don't get you first.
No, no, please no!
The story here is, Gerta Kelly has been peddling this for years, has been wrong about it, and tries to push it through with press releases.
Bang goes that theory:
Dinosaur extinction ‘occurred 300,000 years AFTER asteroid impact’

Whoops, thanks decimon. :’)
13th impact crater associated with K/T boundary
From Tom Van Flandern* Received 5.11.03
Last year, a British team of scientists announced the discovery of a multi-ringed crater (named Silverpit) with a central peak beneath the floor of the North Sea, believed to have been caused by an asteroid impact between 60 million and 65 million years ago [1-4]. The crater has 10 concentric rings from 2-20 km in diameter. The rough dating suggests that the asteroid that caused Silverpit might have been a chunk that broke off the larger asteroid that hit the Yucatan Peninsula 65 million years ago. Together with the Chicxulub and other craters, this discovery gives new support to the idea that killer objects from outer space may have sometimes arrived in pairs or even swarms. “It’s so clear,” said Dr. Gerta Keller, a geologist and paleontologist at Princeton, who studies the links between cosmic bombardments and life upheavals. “A tremendous amount of new data has been accumulated over the past few years that points in the direction of multiple impacts.”
Actually, that brings the list of impact craters sometimes associated with the K/T boundary (65Ma) to 13. These are: Beyenchime-Salaatin (Siberia), Eagle Butte (Oregon), Upheaval Dome (Utah), Manson (Iowa), Kara (Western Siberia), Kamensk (Siberia), Gusev (W. Russia near Ukraine), Unnamed (Pacific Ocean), Chicxulub (Yucatan), Belize (south of Yucatan), Haiti (Caribbean), Alvaro Obregón (N. Mexico), Silverpit (North Sea) [5-10]. However, the global distribution of these impacts argues strongly against chunks off a parent asteroid, which would be expected to have much less than a hemispheric distribution, assuming Earth’s atmosphere is the agent responsible for the break up. Capture and tidal break up by Earth, similar to Jupiter’s capture of Comet Shoemaker-Levy 9, is extremely unlikely (by a factor of over 10 million) because Earth has a much smaller mass and is closer to the Sun. The clear implication of this global terrestrial cratering cluster is the explosion of a planet-sized parent body in the main asteroid belt, a hypothesis for which considerable astronomical evidence already exists [11-22].

More and more Epicycles!!!
Maybe the 14th will be the one that proves it!
Thanks! I’m a little surprised that a British team was involved, since there’s a pronounced antipathy toward the impact extinction models among the teadrinkers.
Lawyers?
There was a much, much bigger one a billion years or so ago.
Google SUDBURY METEOR
Dinosaurs died out from global cooling. It happened like this: meat eaters gradually overtook the plant eaters which had kept the ‘flatulence’ gases at a heat sustaining level; when the flatulence curve plummeted, the temperatures did too, and the planet fell into a massive ice age, until the plant sea creatures’ methane production from fecal build up on the sea floors was able to once again raise the flatulence quotient via methane releases from the ocean beds with an asteroid/meteoroid impact. Lawyers and lying liberals are functioning much the way plant eaters did ... but the Sun is fighting back, stopping its spots which counters the lawyer and liberal flatulence quotient. Moral of the story: Al goreghoul needs hundreds-of-millions more vegetarians so he can earn his nobel prize.
The newest research....suggest that the Chicxulub impact predates the K-T boundary by as much as 300,000 years.
So let me get this straight. The dinosaurs didn't die out 65 million years ago. They died out 64.7 million years ago.
Or, are they really trying to tell us they can tell the differnce between 64.7 and 65 million years ago?
I think it all started when they found one of their own:

North Sea crater shows its scars By Jonathan Amos BBC News science reporter
What is thought to be the UK's only space impact crater has been mapped in detail in 3D for the first time.
The so-called Silverpit structure lies several hundred metres under the floor of the North Sea, about 130km (80 miles) east of the Yorkshire coast.
The new pictures show a spectacular set of rings sweeping out around a 3km-wide (1.8 miles) central hole.
Researchers report their description and interpretation of the images in the Geological Society of America Bulletin.
Dr Simon Stewart and Phil Allen detail how the crater's features would have developed from the cataclysmic fall of an asteroid or comet about 60-65 million years ago.
"I'm 99% certain - as certain as you can be - that this is an impact structure," Phil Allen told the BBC News website.
