Researchers discovered fossilized Megalodon tooth after diving expedition in a flooded cavern in Mexico

The transcript discusses a diving expedition in the Sox Senote, a flooded cave in Merida, Mexico, where researchers discovered a tooth belonging to a Megalodon, a giant shark species that lived millions of years ago. The Megalodon was the largest known shark, with significant size and jaw width. Other shark teeth, such as those from the Saw Shark and Mako Shark, were also found, likely from the same geological period. The Sox Inote is Merida's third-largest flooded cavern, and researchers are mapping the cave system. The name 'Sox' means 'shark' in the Mayan language, and a cenote is a natural sinkhole.

Explain the geological significance of the Sox Senote as reported by Excelsior.

What does the term 'cenote' refer to in the context of the Mayan language?
