The Era of The Cambrian Explosion is a massive, efficient nation, ruled by Opabinia with an iron fist, and remarkable for its enslaved workforce, free-roaming dinosaurs, and devotion to social welfare. The hard-working, cynical population of 4.763 billion trilobites are ruled by a mostly-benevolent dictator, who grants the populace the freedom to live their own lives but watches carefully for anyone to slip up.

The medium-sized, corrupt, well-organized government juggles the competing demands of Industry, Environment, and Education. It meets to discuss matters of state in the capital city of Burgess Shale. Citizens pay a flat income tax of 57.8%.

The frighteningly efficient Cambrian economy, worth 565 trillion fossils a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. However, for those in the know, there is a large, well-organized, quite specialized black market in Trout Farming, Gambling, Retail, and Tourism. The private sector mostly consists of enterprising ten-year-olds selling lemonade on the sidewalk, but the government is looking at stamping this out. Average income is an impressive 118,649 fossils, but there is a significant disparity between incomes, with the richest 10% of citizens earning 419,241 per year while the poor average 24,267, a ratio of 17.3 to 1.

The nation's politicians are known more for the internet memes they spawn than any of their accomplishments, foreign leaders never seem to want to shake hands with Opabinia, the horniness of the great-horned anomalocaris is considered a national priority, and the government's official stance on religion is that it is so very silly. Crime is a major problem, perhaps because of the country's complete lack of prisons. The Cambrian Explosion's national animal is the anomalocaris, which frolics freely in the nation's many lush forests, and its national religion is Cambrian-Primitivism.

The Cambrian Explosion is ranked 312,693^rd in the world and 5,093^rd in The East Pacific for Most Advanced Defense Forces, scoring -11.4 on the Total War Preparedness Rating.
