The phylogenetic results reaffirm the African origin of South American rodents and support a trans-Atlantic dispersal of these mammals during Middle Eocene times, and further extends the gap between first appearances of rodents and primates in South America.
The Tinguiririca Fauna, Chile: Biochronology, paleoecology, biogeography, and a new earliest Oligocene South American Land Mammal 'Age'
A NEW BASAL GLYPTODONTID AND OTHER XENARTHRA OF THE EARLY MIOCENE CHUCAL FAUNA, NORTHERN CHILE
A preliminary phylogenetic analysis of glyptodontids—the first for the group—suggests that Glyptatelinae and Propalaehoplophorinae are paraphyletic and that ParapropalaeHoplophorus is an early diverging glyptid, not closely related to other Santacrucian species.
Early Miocene Paleobiology in Patagonia. High-Latitude Paleocommunities of the Santa Cruz Formation
Paleontologists must often rely on ‘Rosetta stones’— exceptionally preserved examples of ancient ecosystems—in order to make accurate interpretations of the ancient world. For researchers interested…
Notoungulata and Litopterna of the Early Miocene Chucal Fauna, Northern Chile
Three new species of mesotheriid notoungulates are described and a phylogenetic analysis places the three taxa from Chucal as early divergingMembers of the Mesotheriinae, with Eotypotherium chico representing the outgroup to all remaining members of the clade.

Two New Taxa (Caviomorpha, Rodentia) from the Early Oligocene Tinguiririca Fauna (Chile)
ABSTRACT Here we describe two new caviomorphs from the early Oligocene Tinguiririca Fauna of the Andean Main Range of central Chile, representing the most ancient rodents known from the mid to high…

It is indicated that Cerdas is not referable to the Santacrucian, and that the upper limit of this SALMA in the middle latitudes falls somewhere between 17.5 Ma (the top of Chucal) and 16.5–15.3 Ma, which indicates that a diachronous offset may exist at this point in the SALMA sequence between middle and high latitude faunas.
