Some of the teeth could belong to the extinct shark megalodon—one of the largest and most powerful predators to have ever lived.
The pair say that the teeth could date back to the Pliocene epoch and Miocene epoch
"We were looking at the wall and suddenly I saw that there was a little something, I went closer and I see that it was a tooth, apparently that of a sawshark," Vilchis Zapata told"Xoc" is the word for fish in the Mayan language and some say it is the origin of the word"shark" in English. During their explorations of the cave, the researchers also found some fossilized manta ray remains and even human bones. Initial analysis suggests that these belong to a juvenile or younger individual although more investigations are needed.
The Yucatán Peninsula is home to the world's largest flooded cave system, the full extent of which was only discovered last year,. This cave system extends for a staggering 215 miles.
