Short-term occupations at high elevation during the Middle Paleolithic at Kalavan 2 (Republic of Armenia).

2021

The Armenian highlands encompasses rugged and environmentally diverse landscapes and is characterized by a mosaic of distinct ecological niches and large temperature gradients. Strong seasonal fluctuations in resource availability along topographic gradients likely prompted Pleistocene hominin groups to adapt by adjusting their mobility strategies. However, the role that elevated landscapes played in hunter-gatherer settlement systems during the Late Pleistocene (Middle Palaeolithic [MP]) remains poorly understood. At 1640 m above sea level, the MP site of Kalavan 2 (Armenia) is ideally positioned for testing hypotheses involving elevation-dependent seasonal mobility and subsistence strateg…

Precipitation responses to ENSO and IOD in the Maldives: Implications of large-scale modes of climate variability in weather-related preparedness

2020

Abstract This research seeks to address the extent to which indices of large-scale modes of climate variability (El Nino Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD)) can be linked to physical differences in the local mean and extreme rainfall conditions experienced in the Maldives in order to suggest implications for disaster risk reduction (DRR). While some significant differences in precipitation metrics do occur at the local level between different phases of the large-scale modes of climate variability studied, they do not occur for all sites studied. While the constrained availability of historical meteorological data in the region is a limiting factor in this analysis, th…

Lower and Middle Cambrian brachiopods from the Iberian Chains and Sierra Morena (Spain)

2021

Brachiopods from the Lower and Middle Cambrian of the Iberian Chains and Sierra Morena are described. The following taxa occur in the Iberian Chains: "Lingulella" sp., Redlichella cf. bohemica (Barrande), Dictyonina radioplicata sp. n., Micromitra sp., Trematobolus simplex (Vogel), Trematobolus borobiensis sp. n. and Jamesella sp. The taxa "Lingulella" sp. and Sibiria? sp. are reported from the Lower Cambrian of Sierra Morena. Brachiopods constitute several distinct associations: the relatively shallow water Trematobolus assemblage near the Lower-Middle Cambrian boundary interval is followed by the deeper Dictyonina­Redlichella assemblage. The alternation of these assemblages permit us to i…

Periglacial transport distance of Pb derived from small-scale ore veins in the Rhenish Slate Mountains

2008

Abstract The spatial extent of metal contamination caused by small-scale ore veins is increased by periglacial solifluction. Our objectives were (1) to examine the spatial distribution of Pb in cover beds that migrated over Pb ore veins, (2) to calculate the transport distance of ore-derived Pb, and (3) to determine controls on the transport distance. We examined six transects (320–775 m long) in the Rhenish Slate Mountains in West Germany. The transects included four west-exposed and two east-exposed slopes with inclinations between 2–20°. All transects were forest-covered and located at 280–450 m above sea level. Soils were Dystric Cambisols and Stagnic Luvisols. Samples of 120 B horizons…

Late Pleistocene Human Evolution in Sicily: Comparative morphometric analysis of grotta di San Teodoro craniofacial remains.

2007

Late Pleistocene human evolution in Sicily: comparative morphometric analysis of Grotta di San Teodoro craniofacial remains. D'Amore G, Di Marco S, Tartarelli G, Bigazzi R, Sineo L. Source Laboratorio di Archeoantropologia, Soprintendenza per i Beni Archeologici della Toscana, Via dei Rossi 26/A, 50018 Scandicci, Firenze, Italy. Abstract The paleoanthropological remains from Grotta di San Teodoro near Acquedolci (province of Messina, Italy) represent the oldest and largest skeletal collection yet found documenting human settlement of Sicily. The sample, attributed to the Late Epigravettian (between 14,000 and 10,000 years B.P.), consists of seven variously complete adult individuals (San Te…

SEA LEVEL CHANGES DURING THE HOLOCENE IN MALTA AND BARI, CENTRAL MEDITERRANEAN

2012

During the last decade several papers have been published to estimate the relative sea-level change from coastal archaeological indicators in many locations of the Italian coasts and the Mediter-ranean Sea. Anyway, the use of the archaeological information has been poorly focused for Middle Ages and the Bronze Age, due to a few of available coastal installations for these periods. In this paper, we focus on two areas of the Mediterranean, namely the coasts of Malta island and Bari, in Apulia (Southern Italy), that displays coastal archaeological markers of the Bronze age and Middle ages, respectively. The elevation of the selected markers were compared against the latest model prediction of…

New Evidence of MIS 3 Relative Sea Level Changes from the Messina Strait, Calabria (Italy)

2021

Investigation of sea-level positions during the highly-dynamic Marine Isotope Stage 3 (MIS 3: 29–61 kyrs BP) proves difficult because: (i) in stable and subsiding areas, coeval coastal sediments are currently submerged at depths of few to several tens of meters below the present sea level

A stalactite record of four relative sea-level highstands during the Middle Pleistocene Transition

2017

International audience; Ice-sheet and sea-level fluctuations during the Early and Middle Pleistocene are as yet poorly understood. A stalactite from a karst cave in North West Sicily (Italy) provides the first evidence of four marine inundations that correspond to relative sea-level highstands at the time of the Middle Pleistocene Transition. The speleothem is located ∼97 m above mean sea level as result of Quaternary uplift. Its section reveals three marine hiatuses and a coral overgrowth that fixes the age of final marine ingression at 1.124 ± 0.2, thus making this speleothem the oldest stalactite with marine hiatuses ever studied to date. Scleractinian coral species witness light-limited…

Preservation of modern and mis 5.5 erosional landforms and biological structures as sea level markers: A matter of luck?

2021

The Mediterranean Basin is characterized by a significant variability in tectonic behaviour, ranging from subsidence to uplifting. However, those coastal areas considered to be tectonically stable show coastal landforms at elevations consistent with eustatic and isostatic sea level change models. In particular, geomorphological indicators—such as tidal notches or shore platforms—are often used to define the tectonic stability of the Mediterranean coasts. We present the results of swim surveys in nine rocky coastal sectors in the central Mediterranean Sea using the Geoswim approach. The entire route was covered in 22 days for a total distance of 158.5 km. All surveyed sites are considered to…
