Comments:Paleontologists reaffirm the cause of dino extinction
Would it be possible to provide a link or DOI to the article in question so that people could look at the paper themselves if they're interested? —Preceding unsigned comment added by 22.214.171.124 (talk) 13:27, 29 March 2010 (UTC)

They are wrong again! There is no bone pile associated with the K-T impact.....not even one has been found. The scientists must go back to the drawing board.

A group of 41 paleontologists and researchers reaffirmed the cause of dinosaur extinction. The research team concluded that a giant asteroid killed dinosaurs over 65 million years ago. The asteroid crashed into Yucatán, Mexico creating the Chicxulub crater. Their report was published Friday in the academic journal Science.

I'm no more (or less) persuaded than I was before this group of scientists made this announcement. However, the recently announced 'impact and exit event' theory has increased my belief that the dinosaurs were made extinct by an asteroid impact at Chicxulub. As far fetched as it sounds I really like the concept of an impact and exit event - especially when I reviewed the evidence presented in the theory - even if the 'old boy' scientists don't like the thought of it! I downloaded the theory at this website: www.theimpactandexitevent.com I'd be interested in reading comments from students new to the Sciences - before they go on to (perhaps) being influenced by other, 'accepted' past scientific assumptions. This is something that the author of the impact and exit event actually asks for, so it'll be interesting to see the views of these individuals.
its not about disbelieving the story, but i was surprised to hear that this theory is finally confirmed by the scientific society. however, i remain skeptical, because i beleive scintists have been looking for any trails of this great impact and lost the trails of te other theories unil recently they have collected the pieces and got one story which is the great impact. in the end, i still beleive the door is opened to many theories and in my point view its not the end of the mass extinction's great mystrey.
Technically it wasn't confirmed, it was reafirmed (i.e. confirmed again).
They mentioned nothing about the Deccan Traps(massive volcano eruptions), or the possibility that there was more than one impact. As there have been Dinosaurs found ABOVE the K-T boundary, this points to more than one factor leading to the demise of the Dinosaurs.
Actually, they did. They found that the Deccan Trap eruptions happened in two times, 400,000 years before the Chicxulub impact and 500,000 years after. Sadly, the author of the article forgot to note that.
In response to Patrick M's comments, it is suggested within The Impact And Exit Event theory that the Deccan Traps are argued as evidence which supports the 'exit' element of the implied sequence of events the theory covers. Try researching the magnetic composition Bold textof the entire region of the Deccan Traps. IMO the magnetism of the rock supports the impact and exit event theory. Another indicator of the 'rapidity' of the way in which the Deccan Traps was laid down ...could be the absolute lack of erosion during the 'scientificly' derived timescales involved.
