Resumen:
For the first time, a palynologic assemblage is described from the upper section of the Tarma Formation, Peru. It is dominated by monosaccate pollen grains with subordinate striate grains and very few spores. The abundance of Illinites unicus has allowed discussing its systematic state. The assemblage is correlated with the Illinites unicus Palynozone from the Amazonas Basin. A discussion is presented about the age of this assemblage as it relates to others known to belong to the overlying Copacabana Formation in the same locality and neighbouring regions. In this locality the Copacabana Formation bears the Reduviasporonites stoschianus associated with calcareous microfossils and small foraminifera of an Early-Middle Pennsylvanian age. Upon these data and others provided by fusulinids and conodonts from Amazonas Basin the assemblage is considered to be Westphalian C / Late Atokan.
