National Fossil Act

This bill designates the mastodon fossil (genus *Mammut*) as the national fossil of the United States under Title 36 of the U.S. Code. It amends existing law to add "national fossil" to the list of official U.S. symbols, alongside the national anthem, motto, floral emblem, and other designations. The bill has no practical policy impact - it is purely ceremonial and affects no individuals or organizations. It requires no new funding, regulations, or enforcement actions.
