Did you take into account that earth was heavier millions of years ago? Also, you would have to specify where on earth it weighed that amount.
Anyway, pound is an imperial unit for mass, just like slug. The "pound-force" is not part of the imperial units, jut rather of the "English Engineering Units" that differentiate between pound-mass, pound-force, pound-foot and others.
"Pound" is not a unit of force in ANY system. If you really meant force (I doubt that) you should have used lbf. Anyway, noone cares how many Newtons of force the earth exhibited on that animal, all the metric-using people in this thread are interested in its mass. All scales used to weigh something display kg (or pounds), so units of mass.
The dino would need to be even lighter if the earth was heavier because the force of gravity would be higher, but in general differences in gravity across the earth's surface amounts to a rounding error. For example, you're probably looking at 2000 ish miligal from the top of a tall mountain to sea level difference in gravity, or .02m/s^2 difference.
From mountain to sea level yeah but the difference between Equator and North Pole is almost 1% because Earth is not a perfect sphere.
