A well preserved sample of Pyrotherium is described from at least 2 stratigraphic horizons in the Salla Beds of Bolivia. This sample is essentially indistinguishable from, and therefore conspecific with, the species P. romeri from Argentina. This represents the 1st description of this large herbivorous mammal outside of the classic Pyrotherium Beds of Argentina. The presence of this biochronologically diagnostic taxon further supports previous assignments of a Deseadan (Oligocene) age for the Salla Beds of Bolivia.
