Human Skull Found in Underwater Cave

on March 31, 2011

Divers exploring a labyrinth of underwater caves on the Yucatan Peninsula have recently discovered a human skull and some mastodon bones hidden deep beneath the water. Some scientists speculate that the skull “might be the oldest evidence of humans in the Americas.”1

The unusual discovery was made as divers descended into a pit they found inside the cave. The pit is called Hoyo Negra, which means “black hole” in Spanish. Divers had to travel several thousand feet through the underwater cave system to reach Hoyo Negra. This was accomplished by using special equipment, such as underwater scooters. The human skull and mastodon bones were found approximately 120 feet down into the pit, which is nearly 200 feet deep.

How did mastodon remains and a human skull end up in an underwater cave system? It’s hard to know the answer. Evidence of bonfires was found in some of these underwater caves2, so the cave was probably above water at some point in the past. What an exciting discovery!

Have you ever wondered how caves form? It certainly doesn't take millions of years. Caves “could have formed rapidly during the closing stages of, and after, the worldwide Flood of Noah’s day. With the incredible amounts of water from the Flood, the increased carbon levels from all the decaying matter and the related tectonic activity, the global Flood described in Genesis 7–8 produced the right conditions for caves to form very quickly.”3
