Article: Pyrotherium, a large enigmatic ungulate (Mammalia, incertae sedis) from the Deseadan (Oligocene) of Salla, Bolivia

A well-preserved sample of Pyrotherium is described from at least two 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 first 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.
