Resumen:
We describe the oldest Paucituberculata marsupials, from the La Barda and Las Flores localities (Argentina; Late
Palaeocene, and EarlyMiddle Eocene), as well as from the Itaboraí Basin (Brazil; Late Palaeocene). The new taxa
are represented by very scarce, although well-preserved, dental remains. A parsimony analysis was performed in
order to evaluate the phylogenetic affinities of these taxa. Representatives of both Riolestes capricornicus gen.
et sp. nov. and Bardalestes hunco gen. et sp. nov. appear to be basal paucituberculatans, and their molar
features give clues on the early evolution of the representatives of this order. Within the Paucituberculata we
recognize two major clades: Caenolestoidea and Palaeothentoidea. We conclude that pseudodiprotodont marsupials
of the traditional literature (i.e. Polydolopimorphia + Paucituberculata) do not form a natural group.
