if I have a mathematical model of the population I can do a simulation
with some programation's language.
You seem to have overlooked the rest of my e-mail. Dinosaurs aren't a single
species, so there is no single population. Besides, we don't know enough
about the environment and the metabolism of Mesozoic dinosaurs to even guess
at, say, carrying capacities. How much food was needed to sustain a
population of "*Omeisaurus maoianus*"? We have no idea.
