Maybe the asteroid impact actually changed the rotational speed of the planet and increased gravity. There, I just created a new theory.
What a shitty way to go that would have been for the dinosaurs and any other giant species. Imagine some ELE hitting humankind but sparing all the little people.
The current difference in apparent gravity between the equator and the poles is about 0.3%.
I think the centrifugal effect squares with angular velocity (plus the bulge of the earth would make the distance from the center of gravity ever so slightly larger), so maybe doubling the rotation speed would bring it up to 1.2%.
So maybe a measureable effect but probably not enough to actually overcome the biological limits on size/mass/weight.
