What if an advanced industrial civilization existed on Earth millions of years before humans... and every trace of it has been erased?

In this episode of The Box of Oddities, Kat and Jethro explore the fascinating Silurian Hypothesis—a real scientific thought experiment that asks whether an ancient technological civilization could have risen, fallen, and disappeared so completely that only faint chemical fingerprints remain in the geological record. From plate tectonics and fossilization to the Anthropocene and mysterious Libyan Desert Glass, it's a mind-bending look at deep time and the unsettling possibility that Earth may have forgotten entire chapters of its own history.

Then the conversation takes a delightfully strange turn into the forgotten world of tyromancy—fortune telling with cheese. Discover how people once searched for signs of love, luck, and the future in wheels of cheese, melted fondue, mold patterns, and even hungry mice. Along the way, Kat uncovers other surprisingly common forms of food divination involving eggs, onions, flour, tea leaves, and more.

Also included: eerie hospital stories that blur the line between coincidence and the supernatural, plenty of offbeat humor, and the wonderfully bizarre conversations that make The Box of Oddities unlike any other podcast.
