"Rio's Cemetery of New Blacks sheds light on horrors of slave trade: Tooth analysis shows Africans taken from wide area ranging from Sudan in the north-east to Mozambique in the south." http://ping.fm/fyNfY

NOTE from SGHRP: Scientists in Rio are using the same tooth analysis technique first used on the bioarchaeological remains in the New York African Burial Ground to ascertain countries of origin for the enslaved men, women and children who were buried in this site. The mid-18th to early-19th century use of this cemetery (1760-1830) coincides with that of Richmond's African Burial Ground (1750-1816).
