Given that these dates differ by no more than the statistical error bars of the measurements (11,000 years), they are basically similar. Thus these new findings provide dramatic affirmation to the idea that the meteorite impression triggered the extinction (although climate-related phenomena prior to that point might have exacerbated stress on these species) [Sanders2013a].

Thus these new findings offer dramatic affirmation to the theory that the meteorite impression caused the extinction (although climate-related phenomena previous to that time may have exacerbated stress on these species) [Sanders2013a].
