About National Megalodon Day
National Megalodon Day takes place on Monday, 15 June 2026. It celebrates the megalodon, the largest shark ever known to have lived, and the science of palaeontology that helps us understand it. Created by the Aurora Fossil Museum in North Carolina, the day is a chance for fossil fans, families and curious minds to marvel at a prehistoric ocean giant.
How to Celebrate National Megalodon Day
This is a day made for curiosity and fun, so there are plenty of ways to dive in:
- Visit a fossil museum – Head to a natural history or fossil museum to see real megalodon teeth and learn how scientists study them. The Aurora Fossil Museum is the spiritual home of the day.
- Go fossil hunting – Many coastlines and riverbeds yield shark teeth. Check a local site, take a guide and see what you can find.
- Hold a megalodon tooth measuring challenge – The biggest teeth measured close to seven inches. Cut out a paper template and compare it to a modern shark tooth to grasp the scale.
- Watch a documentary – Settle in with a film or series about prehistoric sharks and ocean life to learn the facts behind the legend.
- Get crafty with kids – Make a model megalodon jaw, paint shark teeth or build a salt-dough fossil for a hands-on family activity.
- Read up on the science – Explore how researchers estimate the megalodon’s size and diet from fossilised teeth and vertebrae.
- Share megalodon facts online – Post a jaw-dropping statistic about the shark and tag friends to spread a little prehistoric wonder.
- Plan a beach day – Combine the celebration with a trip to the coast, where you can talk about the creatures that once swam those very waters.
What is National Megalodon Day?
National Megalodon Day is an annual celebration of Otodus megalodon, the colossal shark that ruled the oceans millions of years ago. It is also a celebration of fossil science and the museums that preserve and explain it. The day appeals to anyone fascinated by sharks, the deep past or natural history, and it is especially popular with families looking for an engaging way to spark a love of science in children.
When is National Megalodon Day?
National Megalodon Day is held every year on 15 June. In 2026, that falls on a Monday. The date is fixed, so it always lands on 15 June, the anniversary chosen by the museum that created it.
The History of National Megalodon Day
National Megalodon Day was established in 2021 by the Aurora Fossil Museum in Aurora, North Carolina. The museum’s executive director, Cynthia Crane, working with the Aurora Fossil Museum Foundation board and Dr Bruce Worf, selected 15 June as the perfect date to celebrate both the museum and its most famous fossil. The first National Megalodon Day was proclaimed for that day in 2021.
The location is fitting. The phosphate deposits mined near Aurora, an area also known as Lee Creek, have produced some of the finest and best preserved fossilised megalodon teeth in the world. Generations of collectors and scientists have sifted through this material, making the region a genuine hotspot for megalodon discoveries and a natural birthplace for the day.
Since its creation, the day has grown beyond the museum’s walls. Schools, aquariums and science centres now use 15 June as a hook to teach about palaeontology, ocean life and extinction, while shark enthusiasts around the world join in online. If you love marine life, you might also enjoy Shark Week, which celebrates the sharks that patrol our oceans today.
Fun Facts About National Megalodon Day
- The megalodon swam the world’s oceans for around 20 million years during the Cenozoic Era.
- Its bite force is estimated at over 40,000 pounds per square inch, among the most powerful of any animal known.
- The largest individuals may have weighed over 60 tonnes.
- Its serrated teeth could measure close to seven inches long.
- The name megalodon means “big tooth”, and teeth are by far the most common megalodon fossils found.

Why National Megalodon Day Matters
Beyond the thrill of an enormous prehistoric predator, the day champions science education and the work of small museums that keep palaeontology alive. Sparking a child’s wonder at a giant shark can be the first step towards a lifelong interest in science, conservation and the natural world. It is a reminder that the oceans hold extraordinary stories, both past and present.
