This bunch have tested (and re-tested) debris from the Chicxulub impact crater off the Yucatán Peninsula in Mexico. Their findings include a timeline that spans 11,000 years for the impact, almost simultaneous with the Cretaceous-Paleogene extinction. From the article:
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.”
Not a bad timeline after all. Please see: Finally confirmed: An asteroid wiped out the dinosaurs | ExtremeTech
Now. If we can only solve the chicken or the egg question.
