Drilling at Yucatan reveal, they say, microfossils 300,000 years after
supposed extinction:

"Many believe that the impact shrouded the Earth in dust and debris, shutting down plant photosynthesis and leading to the rapid demise of most creatures, from marine microorganisms to dinosaurs."

On a geological time scale, 300,000 years is still fairly rapid. A great many species may have petered to extinction due to the aftermath (sequelae) of the impact, rather than the impact itself. I think this is the thrust behind the K/T impact theory.
