WASHINGTON D.C. — The National Fossil Act has now passed the Senate. This bill names the mastodon as the U.S. national fossil, and was introduced by Senator Mike Braun and Senator Gary Peters and cosponsored by Senator Eric Schmitt and Senator Maggie Hassa.

The National Fossil Act aims to celebrate the unique natural history of the United States, and encourage interest in paleontology.

If the National Fossil Act is passed by the House and signed into law, the mastodon would join the bald eagle, bison, rose, and oak tree as enduring national symbols of the United States.

The mastodon lived more than 13,000 years ago in the Pleistocene era, predominantly on land that would eventually become the United States of America. A fully grown mastodon was over 10 feet tall, weighed more than 11 tons, and was preceded by a pair of 16-foot-long tusks. Unlike its distant cousin, the mammoth, the mastodon was found exclusively in the United States, with its bones being unearthed in every state across the continental U.S.

Mastodon fossils are frequently found in Indiana and Michigan.

The mastodon was made the Indiana state fossil in 2022.

Mastodons have been found in nearly every Indiana county, including notable discoveries in Hebron, Fort Wayne, and Seymour.

“Mastodons embody the spirit of exploration, resilience, and strength that exemplifies our great nation. As a uniquely American symbol, mastodons inspire us to embrace our heritage and to protect our country’s natural treasures. I hope making Indiana’s state fossil our national fossil will inspire young Hoosiers to take an interest in our country’s rich natural history that may be in their own backyard,” said Braun.

“Michigan made history when we uncovered one of the most complete skeletons of the Mastodon ever found, and we continue to find traces of this prehistoric giant all throughout our state,” said Peters. “The Mastodon represents a unique piece of both Michigan’s and our nation’s history. By establishing the Mastodon as our national fossil, we can better preserve that history and inspire a new generation of scientists and researchers to continue their pursuit of discovery.”

The National Fossil Act:

• Section 1 designates the bill as the National Fossil Act.
• Section 2 establishes findings on the role of the Mastodon in American public life.
• Section 3 designates the Mastodon as the national fossil under Title 36 U.S. Code, and makes necessary conforming amendments.
