National Fossil Day is an annual event organized by the U.S. National Park Service in partnership with museums, universities, and scientific organizations to celebrate fossils and promote public awareness of paleontology. It typically takes place in October and features educational programs, fossil-focused events, and outreach activities across the United States. While not a single centralized competition, it often includes national and local art or photo contests, classroom activities, and public programs. The event is open to all ages, including high school students who are interested in paleontology, geology, or earth science. Students can participate by submitting artwork to the National Fossil Day Art Contest (and similar themed contests when offered), attending local National Fossil Day events at parks or museums, or using official lesson plans and activities with their science clubs or classes. Participation is free, and students benefit by deepening their understanding of earth history, connecting with professional paleontologists and educators, and building portfolio material through contest entries and outreach projects.
