Information

ID: 676
Other ID: AA-95577
Type: MicroSample
Subtype: pollen
Site: Caballete
Depositional context: feature

A pollen sample (Lab #576) collected from Operation V, Unit 7, Cuad I19, Feature 69, yielded 91 grains of maize pollen. A radiocarbon date was obtained on a sample of woody plant material from Feature 86 in the same Cuadrant, giving an closely associated indirect date for the pollen sample (Haas et al. 2013: Tables SI01 and SI02).
