Since we know nothing about tyrannosaurid population dynamics, the simplistic 
view is the only one we can start from. We have no idea how many hatchlings 
grew to adulthood, for example, because we have no tyrannosaurid nests; nor 
do we have any specific idea what kinds of taphonomic and preservational 
biases may have been operating. Heck, we don't even know whether there was 
more than one species of large tyrannosaurid in the North American 
Maastrichtian.
