Diets estimated from different proxies such as stable isotopes, stomach contents, and dental
microwear often disagree, leading to nominally well‐supported but greatly differing …

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 …

Carbon isotopic signatures recorded in vertebrate tissues derive from ingested food and
thus reflect ecologies and ecosystems. For almost two decades, most carbon isotope-based …

South America lost around 52 genera of mammals during a worldwide event known as the
Late Quaternary Extinction episode. More than 80% of South American mammals weighing> …

“An enjoyable read that provides a substantial amount of detail on the biology, ecology, and
distribution of these fantastic animals... Highly recommended.”—Choice More than 10,000 …

Fossil sloths are regarded as obligate herbivores for reasons including peculiarities of their
craniodental morphology and that all living sloths feed exclusively on plants. We challenge …

Phylogenetic relationships among sloths (Folivora) have been extensively studied in the
past few decades using maximum parsimony approaches. Recently, Bayesian phylogenetic …

The fossil xenarthrans include giant forms, the ground sloths (Tardigrada), characteristic of
the mammal fauna of the Pleistocene of South America. Although most authors agree in …

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 …
