One hundred million years is a long time, and many resurrected fossil pokemon have struggled to adapt both to an ecosystem dominated by mammals and the dominance of the human species; that said, few experience a greater culture shock than Tyrunt. Tyrunt today are famous for being not only remarkably proud and difficult to tame, but even those who have established a good rapport with their trainers will throw violent, destructive tantrums at even the slightest provocation from others.
Paleontologists are divided as to whether this behavior also existed among ancient Tyrunt, or is a response to the stress of a world their instincts find alien. The fossil record can offer little behavioral analysis, and some have suggested that Tyrunt's tantrums originated as a means of impressing their awesome power onto other pokemon – for Tyrunt are scavengers, and fear is a time-honored means of ensuring others will share their food. This hypothesis is controversial, however, for Tyrunt's tantrums, although destructive, do not let them win fights they would otherwise lose, and many have suggested that the randomness of modern Tyrunt tantrums would cause predators to avoid provoking them by migrating away; a counterproductive strategy for any scavenging pokemon.
Whatever their origins, Tyrunt tantrums pose a serious challenge for any would-be trainer. Although many have attempted various ways to make them feel more at home, and a few have seen modest success by setting the indoor temperature to that suggested by climatological data of Tyrunt's era, it is impossible to turn the clock back far enough to make Tyrunt truly comfortable. Therefore, Tyrunt trainers are advised to carry and decorate with either extremely sturdy or cheap and disposable items, to master the art of a quick poke ball return, and to wear body armor whenever their Tyrunt is outside its ball.
