Pachycephalosaurus

Pachycephalosaurus had one answer to every question, and it was its head.

Its skull was a dome of solid bone — inches thick at the crown, reinforced

with a structure that distributed impact force across the entire surface

like a natural helmet engineered for collision. When territorial disputes

arose, when rivals challenged, when anything at all needed to be resolved,

Pachycephalosaurus lowered its head and charged. The impact could be heard

across the valley. The ground shook. And one of the two combatants walked

away while the other reconsidered its life choices. It was not a subtle

creature. It did not scheme or strategize or negotiate. It found a problem,

it ran at the problem as fast as it could, and it hit the problem with its

face. The remarkable thing is that this approach worked for millions of

years. The Dominion rewarded many survival strategies — armor, speed,

intelligence, size. Pachycephalosaurus proved that sometimes the simplest

strategy is the best: be harder than whatever you hit.
