The Federal Republic of Mesozoia is a mammoth, environmentally stunning nation, ruled by Cenzo Sara with an even hand, and remarkable for its free-roaming dinosaurs, state-planned economy, and stringent health and safety legislation. The compassionate, democratic population of 6.914 billion Mesozoans are fiercely patriotic and enjoy great social equality; they tend to view other, more capitalist countries as somewhat immoral and corrupt.

The enormous, socially-minded government juggles the competing demands of Education, Environment, and Administration. It meets to discuss matters of state in the capital city of Cretacea. The average income tax rate is 79.8%, and even higher for the wealthy.

The powerhouse Mesozoian economy, worth 698 trillion Zoic Dollars a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. The industrial sector is led by the Tourism industry, with major contributions from Book Publishing, Information Technology, and Beef-Based Agriculture. Average income is an impressive 100,993 Zoic Dollars, and distributed extremely evenly, with practically no difference between the richest and poorest citizens.

Soldiers' positions are given away by the glint of their bayonets, the nation has nearly as many history museums as Mesozoans, policies are debated via video essays and tier lists, and new pilots are regularly reminded that they are more expendable than their planes. Crime is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Mesozoia's national animal is the Archaeopteryx, which frolics freely in the nation's many lush forests.

Mesozoia is ranked 318,751^st in the world and 1^st in Argenta Nova for Largest Trout Fishing Sector, scoring -10.2 on the Nemo Depletion Efficiency Index.
