Abstract In the 1970s, Paul Martin proposed that big game hunters armed with fluted
projectile points colonized the Americas and drove the extinction of megafauna. Around fifty …

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 …

Sloths represent one of the most successful South American clades that reached North
America during the Great American Biotic Interchange (GABI). At least four families are …

Sloths are represented today only by two distantly-related small, arboreal, and folivorous
genera. However, the fossil record of the clade is composed of many more taxa, with much …

With their odd cranial features, glyptodonts, closely related to extant armadillos, are a highly
diverse group of the South American megafauna. Doedicurus, Glyptodon, Panochthus, and …

Fishtail projectile points are the earliest widespread projectile type in South America, and
share chronology and techno-morphology with Clovis, the oldest North American projectile …

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

Late Pleistocene sloths were widely distributed and present in a diversity of habitats in
South, Central, and North America and some Caribbean Islands. Late Pleistocene sloths …

Species distribution models (SDMs) are helpful for understanding actual and potential
biogeographical traits of organisms. These models have recently started to be applied in the …

Xenarthrans constitute a relict clade of endemic South American placental mammals with a
long evolutionary history starting, at least, in the early Eocene. Within Xenarthra …
