Mammoth Cave in Kentucky has over 600 kilometers of passageways, but in January 2024, two ancient sharks were dug up there. The length of a Fiat 500, these sharks swam around on Earth millions of years ago when Kentucky was underwater.

Ice and desolation dominate most of Antarctica, and contrastingly, that makes the discovery of a cave on Greenwich Island in 2019 with what looked like stairs built by humans all the more remarkable. Others said it could be part of an ancient civilization or a secret military base.

Who built these stairs? And to what purpose? We may never know, but it’s fun to imagine.

In May 2024, a see-through, 4mm-long crustacean was found in Totem Pole Cave, Australia. The large-clawed, protruding teeth of this little animal represent the smallest of its kind, probably one among many wonders that wait for human discovery.

These tiny “hobbits” stood only 1 meter tall and lived some 12,000 years ago. But despite the diminutive stature, they behaved very cognitively inasmuch as they used fire and tools. They even hunted giant rats, it’s thought. These little humans just remind us that our planet was once populated with various kinds of people.

9. The Peking Man

Peking Man was a kind of ancient Homo erectus that was discovered in China in the 1920s and lived hundreds of thousands of years ago. Smaller and less brainy against modern man, they were nonetheless the apex predators of their time.

The original fossils were lost during World War II, but their plaster casts remain a big part of our information on early human history.

8. Coins of Ancient Origin

Finds such as these afford that very rare window into ancient times when living often meant one was obliged to bury precious things deep in the earth.

In New Zealand’s Waitomo Caves, there are so many glowworms that they light the entire cave with an eerie, bluish-green into the distance. Actually, these “worms” are just the larvae of fungus gnats, but their glow makes for a stunning view.

First discovered by the indigenous Maori people, these caves are now popular among tourists.

6. A Bandit Hideout

A cave on the banks of the Ohio River in Illinois was once home to a gang of river pirates back in the 1700s. Fittingly called Cave-in-Rock, it was a perfect place for thieves to hide. This soon-to-be church in the 1800s remains legendary due to its history of crimes and adventure.

5. Mammoth Bones

It surely is incredible that such a fragile document should survive the rigors of time, untouched.
