I was hoping for some more evidence of causation. The new research is still circumstantial, in that before it was the assumptive cause because the impact was dated to within ~1 million years of the extinction event, and now it's even more assumed to be the cause because it has been dated to within ~11,000 years of the extinction event.
Where was the line drawn for it to be "confirmed"? Is circumstantial evidence the best we can do?
- raverbashing 14y agoThere's also the issue the extinction event is not instantaneous, but took a long time As per wikipedia: "The fossil record shows that the tempo of the K-Pg extinction was extremely rapid, occurring on a scale of thousands of years or less" But it is "confirmed" in the absence of better opposing evidence. Better results probably only with a time machine, or a better explanation
