An improved chronology for the Middle Stone Age at El Mnasra cave, Morocco
North African coastal Middle Stone Age (MSA) sites are key to study the development and expansion of early H. sapiens. El Mnasra cave on the Atlantic coast of Morocco (Témara region) is a crucial site associated with MSA archaeological materials considered advanced cognitive hallmarks of behavioural innovation, such as numerous Nassariidae perforated shells, hematite pigments, bones industry and coastal resources exploitation. We provide new trapped-charges dates (OSL and combined US-ESR ages). Our Bayesian modelling strengthens the new lithostratigraphic interpretation of the cave stratigraphic units (US) and we propose an updated chronostratigraphic model for the Middle Stone Age archaeo-sequence of El Mnasra Cave. We confirm a human presence between 124–104 ka, earlier than what the previous OSL and US-ESR data showed. Our time range intervals allowed us to also extend the age of the MSA occupations considerably to the MIS 4/3 (~62–30 ka), marked by the disappearance of the Nassariidae perforated shells. Outstandingly, our model pushed back the age of the largest record of Nassariidae perforated shells and placed the age of their use by the Aterian groups at El Mnasra from the MIS 5d-5b (~115–94 ka)
Tectonic reactivation of a passive margin landscape: insights from Quaternary river terraces (lower Mondego River, western Iberia)
L’insediamento a bifacciali di Guado San Nicola (Monteroduni, Molise, Italia)
La monografia rappresenta un compendio di lavori specialistici sul sito paleolitico di Guado San Nicola a Monteroduni (Molise, Italia), oggetto di ricerche sistematiche ed indagini interdisciplinari inaugurate nell’area a partire dal 2000 dall'Università degli Studi di Ferrara. Il sito, ascrivibile al MIS 10/11, costituisce un tassello importante nell’ambito della ricostruzione del quadro del popolamento umano della penisola italiana e dell’intero bacino del Mediterraneo, alla luce delle considerazioni crono-stratigrafiche, della ricchezza della documentazione e della presenza di elementi innovativi dal punto di vista culturale quali la padronanza del metodo Levallois e l’uso di percussori in palchi di cervo
Earliest evidence of pollution by heavy metals in archaeological sites
Homo species were exposed to a new biogeochemical environment when they began to occupy caves. Here we report the first evidence of palaeopollution through geochemical analyses of heavy metals in four renowned archaeological caves of the Iberian Peninsula spanning the last million years of human evolution. Heavy metal contents reached high values due to natural (guano deposition) and anthropogenic factors (e.g. combustion) in restricted cave environments. The earliest anthropogenic pollution evidence is related to Neanderthal hearths from Gorham's Cave (Gibraltar), being one of the first milestones in the so-called “Anthropocene”. According to its heavy metal concentration, these sediments meet the present-day standards of “contaminated soil”. Together with the former, the Gibraltar Vanguard Cave, shows Zn and Cu pollution ubiquitous across highly anthropic levels pointing to these elements as potential proxies for human activities. Pb concentrations in Magdalenian and Bronze age levels at El Pirulejo site can be similarly interpreted. Despite these high pollution levels, the contaminated soils might not have posed a major threat to Homo populations. Altogether, the data presented here indicate a long-term exposure of Homo to these elements, via fires, fumes and their ashes, which could have played certain role in environmental-pollution tolerance, a hitherto neglected influence.Francisco J.

Modeling the Past: The Paleoethnological Evidence
This chapter considers the earliest Paleolithic, Oldowan (Mode 1), and Acheulean (Mode 2)
cultures of the Old Continent and the traces left by the earliest hominids since their departure
from Africa. According to the most recent archaeological data, they seem to have followed two
main dispersal routes across the Arabian Peninsula toward the Levant, to the north, and the Indian
subcontinent, to the east. According to recent discoveries at Dmanisi in the Caucasus, the first
Paleolithic settlement of Europe is dated to some 1.75 Myr ago, which indicates that the first “out of
Africa” took place at least slightly before this date. The data available for Western Europe show
that the first Paleolithic sites can be attributed to the period slightly before 1.0 Myr ago. The first
well-defined “structural remains” so far discovered in Europe are those of Isernia La Pineta in
Southern Italy, where a semicircular artificial platform made of stone boulders and animal bones
has been excavated. The first hand-thrown hunting weapons come from the site of Scho¨ningen in
north Germany, where the first occurrence of wooden spears, more than 2 m long, has been
recorded from a site attributed to some 0.37 Myr ago. Slightly later began the regular control of
fire. Although most of the archaeological finds of these ages consist of chipped stone artifacts,
indications of art seem to be already present in the Acheulean of Africa and the Indian
subcontinent
