10% rule. Predators form 5-10% of the population of their prey. For every 20 sauropods, there will be one or at most 2 T-Rexs. Most likely 1 adult and 1 juvenile. This ratio apparently holds good across the animal kingdom. Herbivores form 5-10% of the biomass of the fodder available at any given moment. If the biomass gives out, they migrate. As do their predators.

Yeah, but 20 sauropods across what area is what I’m getting at…20 every square km, or 20 every 100 square km?
Most like 20 sauropods wandered around over 200 sq km of rangeland, then migrated.
