Abstract The use of caves during the Late Middle and Early Upper Palaeolithic in Europe was often characterized by alternation between humans (Neandertals and Anatomically Modern Humans) and carnivores. One of the most important karstic areas in Europe that contains a rich archaeological record during this cultural period is the Cantabrian Region, northern Spain. We explore the archaeological evidence recovered from the lower levels of the stratigraphic sequence in El Miron Cave dated between 27...

Abstract Seaweed consumption by wild, feral and domesticated animals in coastal areas world-wide is currently likely widely underestimated. Seaweed consumption on the Orkney Islands by domesticated animals has become an established part of the archaeological literature, but the extent of seaweed consumption elsewhere is still largely unknown in archaeological contexts. The identification of small amounts of seaweed consumption by collagen δ13C and δ15N values remains problematic, as it is unclea...

Abstract Stable isotope ratio measurements of fish remains from archaeological sites are relatively rare so here we report results of 201 fish remains from two Bronze and Iron Age sites along the Syrian (Tell Tweini) and Lebanese (Sidon) coast to document the inter- and intra-specific variation of the δ13C and δ15N isotope values. Due to poor preservation, successful isotopic results were only obtained from 42 specimens (21%). Our results were combined with previously published fish isotopic res...

The Upper Palaeolithic in Europe was a time of extensive climatic changes that impacted on the survival and distribution of human populations. During the Late Glacial Maximum (LGM), southern European peninsulas were refugia for flora, fauna, and human groups. One of these refugia, the Cantabrian region (northern Atlantic Spain), was intensively occupied throughout the Upper Palaeolithic. Characterising how climatic events were expressed in local environments is crucial to understand human and an...

Abstract Sixteen taxa comprising extinct megafauna and extant species from a single asphalt deposit (Project 23, Deposit 1) at Rancho La Brea were isotopically analyzed (δ13C, δ15N, δ34S) and 14C dated to investigate paleoecology and feeding behavior of terrestrial vertebrates in southern California during the late Pleistocene. The large majority of the 14C dates cluster between ∼35-36 kyr BP, but a range of ages indicate this seep was active from ∼30 to >43 kyr BP. Many of the Smilodon fatalis ...

Abstract Here we present phosphate oxygen isotope (δ 18OPO4) data from horse (Equus sp.) tooth enamel (bioapatite) from early Eemian and early Weichselian find levels at the archaeological site of Neumark-Nord 2, Germany. Based on the relationship between δ18OPO4 of bioapatite, body water, local precipitation and air temperature, these data are used to reconstruct palaeoclimatic conditions contemporary to the different phases of Neanderthal activity at the site. Bulk enamel samples representing ...

Abstract A quality control program was undertaken to test the merit of different techniques for the preparation of Late Pleistocene bone at the A.E. Lalonde AMS Laboratory in Ottawa (Canada). The samples studied here include a mammoth bone (S-EVA 2000) previously dated by other labs (Oxford, Kiel, Mannheim) with results ranging between 35,280 and 31,660 14C yr BP (n = 10), a bison bone (S-EVA 2001) previously dated between 47,300 and 40,200 14C yr BP (n = 9; Talamo and Richards, 2011), and our i...
