In the bowls are roasted maize cobs, which they are offering us to eat - a spontaneous gift.

Within this context, we studied the morphological characteristics of 37 maize cobs and then directly dated them to confirm their age.

Carbonized avocado seeds, maize cobs and remnants of textiles, basketry, mats and rope fragments have been found in those that are bottle-shaped.

Maize cobs are also used as a biomass fuel source.
