I'm not sure if anyone else is interested in paleontology but the latest issue of the scientific journal Science has published findings that solidify the hypothesis that the dinosaurs, along with 75% the other species that existed at the time, were taken out by the Chicxulub bolide impact north of the Yucatan peninsula, Mexico.

I remember hearing a generalized version of this as a kid and it's funny reflecting. Lines drawn by human observation are never as defined as a child's interpretation of things. Like with the whole Pluto not being defined as a planet fiasco. I think it was Connor who posted something previously about how we're never really right (or wrong), we just get more (or less) precise as we go.

Anyway, here are links to what I've read on the latest publication if you're interested in reading more.

... however, European and American scientists have re-tested debris from Chicxulub using state-of-the-art equipment and narrowed the asteroid impact down to a period of 11,000 years, between 66.03 and 66.04 million years ago — almost simultaneous with the Cretaceous-Paleogene extinction. When dealing with geological timescales, a range of 11,000 years is about as accurate as you can get. As the research paper puts it, though, “the Chicxulub impact likely triggered a state shift of ecosystems already under near-critical stress.” In other words, prior to the extinction event, Earth was already teetering on the edge of self-annihilation.


Nice that they can narrow the time 'window' in which it occurred. Other articles on this news tended to state that there might have been strikes in other areas around the globe which might have 'helped' the situation also. Guess until the TARDIS visits for a bird's eye view, we are still speculating and not knowing for certain.

There likely were multiple strikes (at least two) but the narrowing of the range for Chicxulub puts this strike squarely in the time range of being a contributor.
