Analysis of chronologically diagnostic ceramic types conducted in 2003 used a
four digit classification system; in 2004 and 2005, a more refined two digit system was
employed for identification. The ceramic type numbers are presented below in
parentheses following their descriptive label and reflect one or both of the systems.
Appendices 1a and 1b contain listings of all the types contained in both systems along
with their chronological assignment (for further details see Hernández 2003; Hernández
and Doering 2004, 2005).
The Pre-San Lorenzo Olmec Period (c. 1500-1150 BC)
The pre-Olmec period is represented primarily by tecomates; curved walled,
restricted rim jars with no neck (Lesure 1998:19). Examples at El Marquesillo include,
among others, Ojochi phase Achiotal Gray type (c. 1500-1350 BC) (Figure 5.13), Bajío
phase (c. 1350-1250 BC) rocker-stamped (Figure 5.14) and Chicharras phase (c. 1250-
1150 BC) Tatagapa Red types (Coe and Diehl 1980a:139, 150-158) (Figure 5.15).
