Virtual Dinosaurs, like in real world, can be bred to produce new progeny. To avoid Dinosaurs hyperfinlation, there is a limit to how many times a Dinosaur may be bred, up to 5 times
Depending on how many times the Dinosaurs have been bred, breeding a Dinosaur costs $DNS and several $DST. The $DNS component is flexible and liable to change depending on a variety of economic conditions. Dinosaurs can't breed with their children, and siblings can't breed with each other.
