Resumen:
The Paleocene locality of Punta Peligro (Hansen Member of the Salamanca Formation) in Argentina has
yielded not only condylarths but also an extraordinary assemblage of therian mammals derived from Laurasian immigrants
and non-therian mammals, relicts of the Mesozoic Gondwanan radiation. The materials, a left jaw fragment with
the talonid of the second molar and the third molar, and an isolated upper molar, allow the revalidation of Raulvaccia
peligrensis considered previously as a junior synonym of Escribania chubutensis. In addition to other characters, Raulvaccia
peligrensis considered previously as a junior synonym of Escribania chubutensis. In addition to other characters, Raulvaccia

strongly differs from E. chubutensis in its lesser size, the development of the m3 talonid, the presence of a
hypocristid, and a postcristid. Originally Raulvaccia and Escribania were considered as Mioclaenidae, Kollpaniinae,
together with other ungulates from the Santa Lucía Formation, from the early Paleocene locality of Tiupampa in Bolivia.
In contrast to the Tiupampan condylarths, Raulvaccia shares derived characters with E. chubutensis, particularly in the
upper molars, such as a strong parastyle and the presence of hypocone located close to, but well differentiated from the
protocone. These characters support a previous hypothesis which argues for the removal of the Peligran condylarths
from the more primitive Kollpaniinae, and sustains its relationship to the exclusively South American Didolodontidae.
The revalidation of Raulvaccia peligrensis shows that the diversity of placental mammals during the earliest known
Paleocene in Patagonia was greater than previously thought, and supports for the early differentiation of the Didolodontidae.
