A significant !4C dating anomaly on a sample from Monte Verde, reported as “non-cultural deposits,” yielded an age of 6550 + 160 BP (BETA-7824). This age corresponds to a mastodon bone fragment that had been eroded out onto the surface in modern creek bed at the site (Dillehay and Pino 1997: 43-44, Table 3.1).
