Over what time span did these flows spread?
Would an individual dinosaur be overtaken or could they run away?

Or were they pressured by being pushed out of their environments?

Some of the individual flows happened within 50,000 years of each other. I believe the total time of the flows was 750,000 to a million years or so.
