El arte rupestre se caracteriza por manifestaciones culturales ejecutadas sobre rocas en diversas t\u00e9cnicas: grabados por percusi\u00f3n, incisi\u00f3n o raspado, de diferente profundidad incluyendo relieves; concavidades o depresiones artificiales (\u201cc\u00fapulas\u201d o tacitas); pinturas por abrasi\u00f3n (en el caso de carb\u00f3n), ejecutadas con pincel, con los dedos o por sopleteo. Tambi\u00e9n existen impresiones positivas de manos.<\/p>\n\n\n\n

Contamos con pocos estudios de las t\u00e9cnicas de producci\u00f3n de arte rupestre boliviano. Carlos Kaifler (SIARB, Santa Cruz)  document\u00f3 petroglifos en el oriente boliviano y constat\u00f3 diferencias notables respecto al ancho y profundidad de las ranuras, al cuidado y perfecci\u00f3n de la producci\u00f3n de tales grabados. En su estudio de tres sitios de pinturas rupestres en la parte occidental de la Serran\u00eda San Jos\u00e9 constat\u00f3 la existencia de dos t\u00e9cnicas diferentes, seg\u00fan la penetraci\u00f3n de la pintura en el soporte rocoso: pintura acuosa y pintura de m\u00e1s consistencia, m\u00e1s o menos como tiza.<\/p>\n\n\n\n
