Footage shows the moment Vilichis finds a tooth and gives the ‘okay’ sign to show his excitement.
Zapata told local media: ‘We were looking at the wall and suddenly I saw a little something, I went closer and I saw that it was a tooth, that was the first and apparently it belonged to a sawshark.’
According to Vilichis, an initial exam of the thirteen shark dental fossils and their size and shape revealed that they might have belonged to the prehistoric and extinct species of Megalodon shark (Carcharocles megalodon), the mackerel shark (Isurus oxyrinchus) and the sawshark, the last two of which are not extinct.
For now, this finding is of great contribution to the study of Mexico’s prehistory; we will have to wait to find out what fossil studies reveal.
