Expected National Fossil Day Deals

As a Cause-driven observance, National Fossil Day primarily inspires educational initiatives and conservation efforts rather than commercial deals. Organizations like the National Park Service, the Paleontological Society, and the Smithsonian National Museum of Natural History often host special events, virtual tours, and educational programs. Look for opportunities to donate to fossil preservation projects or participate in citizen science. Some local museums or science centers may offer discounted admission or special exhibits. We will update this page with confirmed live events and educational opportunities as October 15 approaches.

National Fossil Day Hero

Mary Anning

Mary Anning (1799-1847) was a pioneering English fossil collector and paleontologist. Despite her humble origins and limited formal education, she made significant discoveries in the Jurassic marine fossil beds along the English Channel. Her findings, including the first complete Ichthyosaur skeleton and a Plesiosaur, profoundly influenced early paleontological thought and challenged existing scientific understanding of Earth's history.

National Fossil Day FAQs

When is National Fossil Day?

National Fossil Day 2026 falls on Thursday, October 15, inviting enthusiasts to explore the ancient world preserved in stone. This annual observance highlights the scientific and educational value of fossils.

What is the oldest fossil ever discovered?

The oldest known fossils are microfossils of bacteria, found in rocks in Western Australia, dating back approximately 3.5 billion years. These ancient organisms provide crucial insights into the earliest forms of life on Earth.

How many types of fossils are there?

There are numerous types of fossils, broadly categorized into body fossils (actual remains like bones or shells) and trace fossils (evidence of activity like footprints or burrows). Within these, scientists identify many sub-types based on their formation and composition.

Is National Fossil Day a federal holiday?

No, National Fossil Day is not a federal holiday. It is an annual event established by the National Park Service in 2010 to promote public awareness of fossil resources and the science of paleontology.

How to Observe National Fossil Day

Hug a paleontologist
Paleontologists are pretty incredible people. They go through lots of schooling and training to be able to study the fossils of all kinds of organisms. It’s because of them that we know a lot about the last few billion years of our planet’s history. Show your appreciation by giving them a hug, and asking them to tell you more!
Check out local events
Every year, the National Park Service partners with various organizations, universities, museums and more to celebrate National Fossil Day. Through field trips, classroom instruction and outdoor activities, they’re spreading awareness about this important holiday.
Visit Your Nearest National Park
Many national parks are passionate about introducing future generations to the science behind fossils and paleontology. These may include anything from scavenger hunts, to multi-day ranger-led activities. Visit your nearest national park and discover all there is to know about this fascinating science!

4 Fun Fossil Facts

They’re insanely valuable
The highest amount ever paid for a dinosaur fossil was $8.3 million (they named it “Sue”).
They can be enormous
The largest intact fossil ever discovered was a whopping 4 square miles!
Anything can be fossilized
The smallest fossil on record was just 2/10 of a millimeter (it was of a 50-million-year-old parasite).
They’re ridiculously old
Next time you're feeling old, just remember some fossils date back to 4.1 billion years.

Why National Fossil Day is Important

We can learn about our planet
A fossil is evidence of past life that’s been preserved in rock. This helps us discover all kinds of shells, plants, animals, and more that existed long before our time. This information helps us understand what was happening during each part of our planet’s history.
We can understand the progression of time
By looking at fossils, researchers have been able to understand how and when organisms appeared and disappeared throughout the passage of time. This is how they’ve been able to divide up the events in our planet’s history into different periods.
We can look toward the future
Each fossil tells a story of the organism it encapsulates, and the details of when it was on the earth. By examining fossils, we can use these stories to help inform us about the future, and how environmental factors (as well as man-made ones) will help influence our planet for future generations.
