Unfortunately for most of these asteroid impact scenarios, there is NO hard evidence that the dinosaurs were eradicated in a single catastrophic event that scorched or enshrouded the earth for a few short months or years. To be sure, those creatures appear to have died out in a geologic "instant"; but that "instant" may have lasted half-a-million years or more. That's plenty of time for a gradual extinction by other than sensational processes.
