As in Australia, Pleistocene rock art is relatively abundant in Europe, but it has so far received much more attention than the combined Ice Age paleoart of the rest of the world. Since archaeology initially rejected its authenticity for several decades, the cave art of France and Spain and the portable paleoart from various regions of Europe have been the subjects of thousands of studies. It i...

—Throughout the late Quaternary, the Sahul (Pleistocene Australia–New Guinea) vertebrate fauna was dominated by a diversity of large mammals, birds, and reptiles, commonly referred to as megafauna. Since ca. 450–400Ka, approximately 88 species disappeared in Sahul, including kangaroos exceeding 200kg in size, wombat-like animals the size of hippopotamuses, flightless birds, and giant monitor li...

A piece of left parietal of a Middle Pleistocene hominid, recovered from the Upper Bodo Sand Unit, in the Middle Awash, Ethiopia, is described anatomically and compared to Middle Pleistocene hominids and modern Homo sapiens. It bears several primitive features and has important implications for the original Bodo skull, found at the same stratigraphic level in the same area. The new fossil skull...

Pleistocene rock art is abundant in Australia, but has so far received only limited attention. Instead there has been a trend, begun over a century ago, to search for presumed depictions of extinct megafauna and the tracks of such species. All these notions have been discredited, however, and the current evidence suggests that figurative depiction was introduced only during the Holocene, never ...

This comprehensive overview considers the currently known Pleistocene palaeoart of Asia on a common basis, which suggests that the available data are entirely inadequate to form any cohesive synthesis about this corpus. In comparison to the attention lavished on the corresponding record available from Eurasia’s small western appendage, Europe, it is evident that Pleistocene palaeoart from the r...

This study examines the phylogeographic structure within the Patagonian lizard Liolaemus petrophilus and tests for patterns of between-clade morphological divergence and sexual dimorphism, as well as demographic and niche changes associated with Pleistocene climate changes. We inferred intraspecific relationships, tested hypotheses for historical patterns of population expansion, and incorporat...

Marine sediment records from the Oligocene and Miocene reveal clear 400,000-year climate cycles related to variations in orbital eccentricity. These cycles are also observed in the Plio-Pleistocene records of the global carbon cycle. However, they are absent from the Late Pleistocene ice-age record over the past 1.5 million years. Here we present a simulation of global ice volume over the past ...

In recent decades the study of stone artefact technology has made many technical advances and substantial contributions to the archaeology of many regions. Until recently, mainland southeast Asian has benefited little from these advances, in part because of the paucity of evidence and in part because of prevailing conceptual frameworks that were poorly suited to the available evidence. The Midd...

Evolutionary changes in European small mammals during the second half of the Middle Pleistocene, from the Likhvin (Holsteinian, Hoxnian) Interglacial (MIS 11) to the beginning of the Mikulino (Eemian) Interglacial (MIS 5e), that is between 424 ka BP and 130 ka BP were traced. Trends in evolutionary change were documented, and East European and West European faunas were compared. An integrated a...

The early Neandertal sample from Krapina preserves twenty partial scapulae, from immature and mature individuals, males and females. Their relatively broad scapulae and narrow glenoid fossae, similar to those of most Neandertals and contrasting with those of most early and recent modern humans, appear to be characteristic of archaic Homo generally, and they are therefore a retained ancestral co...
