For retracing the birthplace of humans and animals in Central America, Ashley Sharpe, a doctoral student from the University of Florida, has used dinosaur craters and prehistoric tooth evidences. His study has been published in the November issue of PLOS ONE.

Tooth enamel incorporates substances from one’s childhood’s local environment. Therefore, using teeth evidences of the Mayas to trace an individual’s movements can provide hints about slavery practices and marriage alliances. Studying individual Maya lives can help archaeologists figure out their enemy villages, allies, communication methods, and travel places.

They grinded up millennia-old teeth, and inserted the particles into an inductively coupled plasma mass spectrometer with temperature higher than that of the sun, to isolate the lead.

In ancient times, people were the product of the areas that they grew up on. Same is the case today. If an anthropologic study will be carried 1000 years from now on a native Floridian’s remains, the lead in his teeth with will be similar to another remain from today’s polluted Florida, says John Krigbaum, a co-author.

Archaeologists will now use these pre-historic teeth evidences to match the lead with dinosaur craters in bedrocks from specific locations.
