Did the climate changes cause the extinction of the Late Pleistocene gomphotheres in South America? [PDF]
A global wave of megafauna extinctions occurred between 50,000 and 10,000 years ago, impacting numerous large continental mammals that are crucial to ecosystem dynamics.

The Eocene South American metatherian Zeusdelphys complicatus is not a protodidelphidid but a hatcheriform: Paleobiogeographic implications [PDF]
Zeusdelphys complicatus is one of the most enigmatic metatherians from the Itaboraí Basin. The type and only known specimen was previously regarded as the upper dentition of Eobrasilia; an M4 of a new taxon; an M3 of a Kollpaniidae (now regarded as a ...

The Diversity of South American Equus: Did Size Really Matter?
The extant horse genus Equus originated in North America, probably during the late Miocene/early Pliocene, and its entrance into South America was possibly related to one of the last four stages of the Great American Biotic Interchange.

Ecological limiting factors of early hominins in western Eurasia
Introduction. Early hominin (Homo ex. gr. erectus) dispersals from Africa into western Eurasia took place during the Early Pleistocene. Evidence points to the presence of humans in Western Europe, specifically Spain, around 1.1-1.2 Ma and in the ...

A large marine eosauropterygian reptile with affinities to nothosauroid diapsids from the Early Triassic of British Columbia, Canada [PDF]
Sauropterygia, one of the main clades of Mesozoic marine reptiles, diversified shortly after the Permo-Triassic biotic crisis and afterwards remained one of the major components of Early Triassic and later Mesozoic marine ecosystems.
