Ancient Maize Map

Information

ID: 377
Other ID: UCR-3417
Type: MicroSample
Subtype: phytolith
Site: Aguadulce
Depositional context: midden

Maize phytoliths were recovered from milling stones (edge ground cobbles) in the lower levels of Zone C (Piperno and Pearsall 1998). These samples were indirectly dated by AMS dated phytoliths recovered from sediments surrounding the tools (Piperno et al. 2000).
