A Japanese scholar leading a multiyear archaeological project in Bolivia says his team has found a small human skeleton well over 1,000 years old in this year's excavation, the first discovery of its kind in that country.
"The well-preserved skeleton was very small in size, about 70 cm tall, with a disproportionately large head, but it had characteristics of an adult," Katsuyoshi Sanematsu, a professor of anthropology at Rikkyo University in Tokyo, said in a recent interview.
The dating analysis of a carbon sample extracted from a neck bone showed that the skeleton dates back to around 700 A.D.
