The palynomorphs are, in general, poorly preserved, moderately carbonized, brown to dark brown, and often pyrite-impregnated.
This allowed observation of opaque (carbonized) microfossils, and also assessment of the fossil nature of the isolated microstructures.
A fine-grained, crudely stratified and reversely graded zone (30 cm thick) containing rare carbonized twig and leaf fragments occurs at the base.
Within the chamber, the matrix containing the sherds was dark black and appeared to consist of almost pure carbonized material with little soil intermixing.
The relative abundance of uncarbonized plant specimens in association with carbonized materials is discussed.
Our limited data suggest that the range of taxa represented by carbonized plant macrofossils preserved in the elite core contexts differs slightly from that of periphery.
Carbonized remains of maguey plants suggest that maguey fiber may have also been available for spinning.
In addition, the core yielded a significantly larger volume of carbonized materials, in spite of the fact that a greater number of flotation samples were recovered from the peripheral zone.
