This study presents pathological conditions observed in the clavicular joints of the extinct
giant ground sloth Megatherium americanum. Clavicles are key for shoulders and forelimbs …

Stable isotope analyses are powerful tools for reconstructing ancient ecologies and
ecosystems, as they are independent of morphology and directly reflect dietary ecology. The …

Abstract The La Venta fauna of Colombia (~ 13.5-11.5 Ma) represents the most diverse
Tertiary locality in the neotropics, with 75 mammal species and a highly non-analogue …

From the time that the first xenarthrans appeared as early armadillos in the Early Paleocene
Itaborai, the group diversified into strange and wonderful forms. Besides the Dasypodidae, a …

My research illuminates new aspects of the ecological and evolutionary controls on spe-cies
invasions of new ecosystems and of the consequences of species invasions for their new …

The aquatic sloth, Thalassocnus, is one of the most intriguing lineage of mammal known
from the southern pacific coast of South America during the late Neogene. It was initially …

Sloths are a curious group with a rich fossil history but enigmatic ecology. Proxy techniques
like stable isotope analysis (SIA) can provide insight into the dietary ecology of extinct and …

The present thesis aimed to contribute to the knowledge about the Cenozoic Megafauna
from the American continent. The focus was on both the Pleistocene Megafauna from South …
