The Ediacaran-early Cambrian is a significant time of geological history in terms of biodiversity dynamics. During this time-span a particular soft-bodied fauna developed and disappeared, being replaced by the emergent skeleton-bearing faunas. This very special feature not only gave rise to an abundant fossil record but also triggered the bioturbation of strata, thus generating the agronomic revolution comparable to the revolution produced by mankind upon discovery of the possibilities offered by agriculture. Several outcrops of rocks from that period in northwestern Argentina provide examples spurring a general overview of the major evolutionary trends in the Ediacaran-lower Cambrian seas of the region.
