The Matriarchy of Mastodonsaurus is a colossal, pleasant nation, remarkable for its irreverence towards religion. The quiet, industrious population of 4.938 billion Mastodonsaurusians have some civil rights, but not too many, enjoy the freedom to spend their money however they like, to a point, and take part in free and open elections, although not too often.

The relatively small government juggles the competing demands of Defense, Healthcare, and Law & Order. The average income tax rate is 18.7%, but much higher for the wealthy.

The Mastodonsaurusian economy, worth 241 trillion Delta Eagles a year, is fairly diversified and led by the Tourism industry, with significant contributions from Information Technology, Soda Sales, and Woodchip Exports. State-owned companies are reasonably common. Average income is 48,766 Delta Eagles, and evenly distributed, with the richest citizens earning only 2.5 times as much as the poorest.

War criminals are given full state funerals, seven-year-olds debate for weeks on the merits of the Oxford comma, women who walk into the ladies' changing room are accused of being Peeping Toms, and professional athletes juggle part-time jobs to avoid bankruptcy. Crime is relatively low. Mastodonsaurus's national animal is the Kitsune.

Mastodonsaurus is ranked 98,705^th in the world and 1^st in Arlington for Most Rebellious Youth, scoring zero on the Stark-Dean Displacement Index.
