So I stepped on a giant prehistoric snail on the way to work.

Cities around the world have the fossilized remains of ancient life embedded in their infrastricture. The builders usually didn’t even know it.

If you look closely at the stones of certain buildings in your area, you might find fossils stuck in the walls or floors. Or in a bridge or paving stone or any other stonework. We use huge amounts of rock in constructing our cities, and often they just happen to have fossils embedded in them.

Sometimes it’s deliberate, but sometimes it’s only later that we notice that some of the stones have fossils. There’s probably many times more hidden beneath the surface.

There’s fossils built into the Jefferson Memorial in Washington, D.C. Not just that, of course. They’re everywhere. You just have to look for them. A good geologist can often tell a sedimentary rock (the kind more likely to have fossils) just by looking.

Christopher Barr, a geology expert in Washington, D.C., has been hard at work obsessively cataloging the fossils you can find just by walking around in public in the nation’s capital. No museum required.

The BBC has video showing these ancient treasures hidden in plain sight in London.

Here’s where to find a few in Manhattan. They can also be found in a bathroom in Florida, a church in England, and a department store in Tokyo.

They’re everywhere!

Have you ever seen a fossil hidden in plain sight? Keep an eye out and maybe you will.

Let us know if you do.

  1. We love fossils! Once we stayed at a motel in Tennessee and the entire exterior was fossilized rock – seashells everywhere. We’ve got quite a collection.

  2. That’s cool! I don’t own any fossils at all. Always wanted one.

    I hope you had fun on your Tennessee adventure.
