You won’t believe bacteria created this ‘lost city’

Turns out a "lost city" off the coast of an island in Greece was never inhabited by humans at all.

"Ruins" near Zakynthos Island include columns, pavement, disc and donut-shaped structures, pipes, and tiles. Divers thought they'd found a flooded ancient city.

However, analysis has now revealed these formations were created by microscopic bacteria in a process called concretion.

How did that happen?

Basically, bacteria fed on methane seeping up through Earth's crust and left behind these structures made out of a form of calcium. Different forms of methane release created the different shapes.

In fact, similar structures are found in many places on the ocean floor--but mostly in very deep water, not near the shore.

Oh, and these things are way too old to be a human city. Like, 5 million years old.
