Resumen:
We describe the oldest South American Tertiary therian mammal
from Danian-equivalent strata of northwestern Chubut
province, Argentina (Fig. 1). The specimen is an isolated lower
molar most likely pertaining to a polydolopimorphian marsupial,
a group known from the Late Cretaceous of North America as
well as later Paleocene and Eocene deposits in South America.
The derived nature of this bunodont marsupial provides evidence
for an evolutionary radiation of marsupials in the earliest
Paleocene or Late Cretaceous of the Americas.
