Problem No. 1: A "smaller" earth would mean greater gravity (mass
distributed in a smaller volume = greater density = higher
gravitational attraction).

Problem No. 2: A smaller mass to the Earth in the Mesozoic would mean
that mass accumulated in the last 200,000,000 years. Where are the
molten crust and craters from the impacts as the extra mass rained
down?

Problem No. 3: Smaller mass would mean that the atmosphere would have
"evaporated" into space because of a lowered escape velocity.
Nicely done pseudoscientific BS, though!

plus an altered orbital position for the earth, likely affecting the
climate. And an orbital affect on our moon.

For more fun along the same lines, I recommend Worlds in Collision by
Velikovsky

Most of the mystery surrounding some dinosaurs revolves not around the
scale of the entire animal but the problem of how the seimosaur-types
could possibly eat enough, given the mouth/body size ratio. It's as if a
human had to eat with a head the size of a large peanut!
