Question

Dinosaur demise didn't spur species?

Answer 1

What actually do you mean. What are you trying to say?

Answer 2

It did "spur" some species in a way.  We wouldn't be here now if they hadn't died off.  But it wasn't an immediate thing.

Once dinosaurs were out of the picture, many ecological niches were unfilled.  The age of mammals could never have gotten itself established if major predators were running around eating everything of significant size.  Mammals underwent an adaptive radiation after the demise of the dinosaurs, but for all the time they existed alongside dinosaurs, they remained inconspicuous little rodent-like forms.

Answer 3

I would guess it didn't have anything to do with "spurring" our species. There was a 140 million gap between us I believe, give or take a year or two.
