National Fossil Day is observed each year on the Wednesday of the second full week in October. The day celebrates fossils and the important scientific clues they provide about ancient plants, animals, ecosystems, and life on Earth long before humans existed.
History of National Fossil Day
The first National Fossil Day was held on October 13, 2010, during Earth Science Week. It was organized by the National Park Service and many partner organizations to highlight the scientific, educational, and cultural value of fossils.
Fossils help scientists understand extinct species, ancient environments, evolution, climate change, and the long history of life on Earth. Each year, National Fossil Day events encourage museums, parks, schools, universities, and families to learn more about paleontology and the importance of protecting fossil resources.
