A small tyrannosaur is playing with its siblings. They seem to be play fighting, obviously preparing for when they grow larger.
Tyrannosaur eggs hatch around three months after being laid. When they come out, they are about three feet in length, and weigh five to eight pounds. They are defenseless, having not developed their natural armor or the bone crushing potential of their jaws. Predators are at every corner. Herbivores that encounter them try to crush them before they are able to reach adult age, so they have less to worry about in the future. They are like meatballs with legs to hungry predators such as Quetzalcoatlus and other Tyrannosaurs. Luckily, for the first few weeks of their life, their mother protects them (the father isn’t involved with the chicks, as males are either driven off or eaten by the larger and more dominant female after mating). Even this protection does not last, though. After the first few weeks, the Tyrannosaurs lose their motherly instincts and may even eat her young. For every clutch of 3-4 eggs, about one or two survive to adulthood.
Tyrannosaur chicks only fight their siblings, completely relying on their mother to hunt for food. These fights are usually playful, practicing for when they are larger and must fend for themselves. There is one exception to this rule, however: when there is a runt, the other siblings tend to kill it, and feast on its flesh.
Skills: Tyrannosaurs have a +2 bonus to Listen and Spot checks.
These statistics can also be used for Allosaurs, Ceratosaurs, and other large carnivorous theropod.
