A team of international scientists including Ed Reinhardt, Geography & Earth Sciences, have discovered an almost completely intact skeleton, that of an adolescent girl, in an underwater cave in Mexico. Their findings, published in Science and featured in numerous media outlets including The Globe and Mail, have yielded information about the genetic origins of early North Americans. Reinhardt and his team collected core samples from the pit and analyzed the sediment, microfossils and water chemistry changes over time, to reconstruct the flooding history of the cave system, and to determine the age of the 13,000 year old skeleton.
