Most terrestrial large mammals went extinct on different continents at the end of the
Pleistocene, between 50,000 and 10,000 years ago. Besides the loss in species diversity …

The analysis of stable isotopes in fossil mammals is useful for reconstructing
paleoenvironmental and paleoecological conditions, but has been rarely applied to the …

This book summarizes the evolution of carnivorous mammals in the Cenozoic of South
America. It presents paleontological information on the two main mammalian carnivorous …

This study aims at assessing resource and habitat use, niche occupation and trophic
interactions from a stable isotope perspective on fossil mammals from the Argentine Pampas …

The extinct megamammals Eremotherium laurillardi (weight 6550 kg), Notiomastodon
platensis (w= 6000 kg), Toxodon platensis (w= 3090 kg), Valgipes bucklandi (w= 980 kg) …

Isotopes are one of the best tools to reconstruct the paleoecology of extinct taxa, allowing us
to evaluate their diet (through carbon; C3 and C4 plants), their niche breadth (BA) and the …

The analysis of stable isotopes on fossil mammals has become a widely used tool for
understanding the paleoecology and paleodiet of these organisms. In this work, we study …

Megamammals constituted an important component in the Pleistocene faunal communities
of South America. Paleobiological and paleoecological studies involving different …

Apex predators play an important role in the top-down regulation of ecological communities.
Their hunting and feeding behaviors influence, respectively, prey demography and the …

The diet of extinct giant Xenarthrans is a debated topic, especially for ground sloths, for
which herbivory, insectivory, and carnivory through scavenging or active hunting have been …
