Houchin materially advanced the promised policy by sponsoring H.R. 9191, the National Fossil Act, which would amend Title 36 to designate the American mastodon as the national fossil mammal and Tyrannosaurus rex as the national fossil dinosaur. The bill was ordered reported by the House Judiciary Committee on July 15, 2026, but as of September 1, 2026 it had not passed Congress, been signed into law, or otherwise amended federal law. Because the promised legal designation has not been delivered, but she made a serious legislative attempt during her current federal term, this is not fulfilled and receives an effort badge.
