What are the scenarios based on?
The simulation is based directly off of fossil evidence from the Hell Creek formation in the American Northwest. For example say a fossil T. rex skull has been discovered with the tooth of another T. rex lodged within it and the skull shows signs of healing. From this single piece of fossil evidence we have created a number of different interaction possibilities. The first is to face off against another T. rex in a struggle for dominance in a pack of communal animals, being careful not to truly damage yourself or your opponent and thus weaken the hunting pack. Another could be that two or more scavenging tyrannosaurs meet over a carcass and battle for the right to feed. A third would have two solitary hunters engaged in a territorial dispute. As you can see, from this one piece of fossil evidence we can derive scenarios that represent the hypothesis that tyrannosaurs may have been social animals possibly even living in packs, or the converse – that they may have been solitary animals.
