Masters Theses
In 1987, Burney and collaborators (Journal of Archaeological Science (1994) 21, 273–281) recovered a ca. 8 m sediment core from the western basin of Laguna Tortuguero, Puerto Rico that spanned the last ca. 7000 calibrated years. They produced a detailed microscopic charcoal record, and from an initial peak in charcoal at ca. 5300 cal yr B.P. suggested that humans had colonized the island some 2000 years earlier than documented by the archaeological evidence then available. In 2008, two sediment cores were recovered from the eastern basin of Laguna Tortuguero. AMS dates on macrofossils indicate the profile extends to 7600 calibrated …
