APPENDIX (Tables 1 and 2) 
Table 1. Comparative alinement of developmental sequence termi- 
nology in 12 Latin American archeological areas. The preceramic 
portion of the chart is stippled for easier recognition. 
Lack of uniformity in terminology is noteworthy, and it should be 
observed that when the same term is employed, it may not label a 
comparable cultural situation in two different areas. Half of the areas 
are represented by developmental terms, such as "horticultural vil- 
lages," "regional developmental," "classic," etc. Two use pottery- 
style distinctions. Three are divided into "preceramic" and "ceramic" 
segments, the latter subdivided into numbered periods, and one uses 
numbered periods exclusively. In the case of Colombia, the complexity 
of areal differentiation and paucity of systematic and intensive ar- 
cheological survey and excavation makes developmental terminology 
premature. In southern Brazil, Venezuela, and Argentina, the choice 
of the numbered period framework seems to be motivated by the fact 
that the introduction of pottery making and agriculture does not set 
in motion the type of cultural elaboration characteristic of the nu- 
clear areas. Level of development remains considerably more uni- 
form, and distinctions are most readily made by reference to the ap- 
pearance of new styles of pottery or combinations of other material 
traits. Such varying local situations illustrate the difficulty in finding a 
framework of sequence terminology applicable to all of Latin America.
