Human Bones Found in Florida Yard Date Back 2,400 Years


Layout of crime scene in yard where bones were found.

When a woman digging in her yard on the Florida Keys last fall turned up a jawbone and part of a human skull, detectives immediately could tell the bones had been there a while — “possibly as long as 75 years,” the sheriff’s office said at the time.  Now the Monroe County Medical Examiner’s office says the results of radiocarbon dating tests are in and the bones are much older — about 2,400 years — placing them in the time period of 200-440 B.C.

Bahamas Caves


The blue holes of the Bahamas yield a scientific trove that may even shed light on life beyond Earth. If only they weren’t so dangerous to explore.

By Andrew Todhunter

We sink into Stargate, sweeping the void with our dive lights. Fifty feet from the surface looms a pale haze, less smoky than fibrous, like a silvery net of faint, swirling cobwebs hovering motion­less in the darkness. It’s a layer of hydrogen sulfide, a toxic gas created by bacterial colonies and decaying organic matter. Divers entering the gas may experience itching skin, tingling, or dizziness; some smell rotten eggs as it penetrates their skin and metabolizes through their lungs. The gas density in Stargate is relatively low, but I’m struck by a wave of nausea as we descend. I glance at my guide, Brian Kakuk—one of the world’s foremost cave divers. He appears unfazed. My head begins to throb; clearly, I’m unusually sensitive to the toxin. In the epic poem Beowulf, “dim serpent shapes” in the depths guard the lake of Grendel and his mother, shielding their lair. The otherworldly mist in Stargate appears to serve a similar role—a poisonous curtain that protects the deeper reaches of the cave.

Twenty years younger, I’d go in a heartbeat.
