Klein (1) challenges two interpretations in Niespolo et al. (2). Regarding his first point, we maintain that Ysterfontein 1 (YFT1) does provide the oldest known example of full coastal adaptation as indicated by the presence of shell middens (cf. ref. 3). Klein inaccurately characterizes the age of the deepest shell midden layers at Klasies River Main (KRM) given in ref. 4. While other workers identify even the oldest light brown sand (LBS) layer at KRM as similar in age or younger than the deepest deposits at YFT1 (cf. refs. 5 and 6), the reference cited by Klein (4) and subsequent dating efforts show that the shell midden lenses in beach-sand deposits within the LBS layer likely postdate the marine isotope stage 5e sea level highstand (∼120 ka) as does the midden at YFT1. However, existing dates suggest that KRM shell middens may, in fact, be younger than YFT1. Layer LBS has been directly dated using multiple techniques that converge on an age of ∼104 ka (5), notably younger than the 95% confidence interval for YFT1 deposition (2). However, complicating matters, a capping speleothem with a U-series age of ∼110 ka is interpreted as a minimum age of the LBS layer at KRM (5). Thus, layer LBS yields conflicting dates and its true age remains uncertain. The next oldest layer at KRM hosting midden deposits (layer shell and sand [SAS]) is definitively younger than YFT1 (5, 7). Thus, there is no basis for the assertion that KRM middens are older than those at YFT1, and we stand by our claim that YFT1 provides the oldest currently known example of systematic coastal resource exploitation.

Modern human behavioral innovations from the Middle Stone Age (MSA) include the earliest indicators of full coastal adaptation evidenced by shell middens, yet many MSA middens remain poorly dated. We apply (230)Th/U burial dating to ostrich eggshells (OES) from Ysterfontein 1 (YFT1, Western Cape, South Africa), a stratified MSA shell midden. (230)Th/U burial ages of YFT1 OES are relatively precise (median ± 2.7%), consistent with other age constraints, and preserve stratigraphic principles. Bayesian age–depth modeling indicates YFT1 was deposited between 119.9 to 113.1 thousand years ago (ka) (95% CI of model ages), and the entire 3.8 m thick midden may have accumulated within ∼2,300 y. Stable carbon, nitrogen, and oxygen isotopes of OES indicate that during occupation the local environment was dominated by C(3) vegetation and was initially significantly wetter than at present but became drier and cooler with time. Integrating archaeological evidence with OES (230)Th/U ages and stable isotopes shows the following: 1) YFT1 is the oldest shell midden known, providing minimum constraints on full coastal adaptation by ∼120 ka; 2) despite rapid sea-level drop and other climatic changes during occupation, relative shellfish proportions and sizes remain similar, suggesting adaptive foraging along a changing coastline; 3) the YFT1 lithic technocomplex is similar to other west coast assemblages but distinct from potentially synchronous industries along the southern African coast, suggesting human populations were fragmented between seasonal rainfall zones; and 4) accumulation rates (up to 1.8 m/ka) are much higher than previously observed for dated, stratified MSA middens, implying more intense site occupation akin to Later Stone Age middens.

An article from the special issue "Eastern African Quaternary Research Association 4th conference" comprising six articles (plus the introduction). This special issue emerged from the PAGES supported meeting: ‘Eastern African Quaternary Climate Change and Variability: A View from the Highlands’ held in Nanyuki Kenya from 23 27 July 2013. ABSTRACT: We compare taphonomically relevant aspects of 6 bone accumulations produced by extant spotted hyaenas Crocuta crocuta striped hyaenas Hyaena hyaena and brown hyaenas Parahyaena brunnea) from eastern and southern Africa (Republic of Djibouti and Namibia) and published accounts. We highlight similarities and differences in the bone cracking/consumption and bone collecting habits of each hyaena species with a view to revealing criteria that might be used to distinguish these species. Four parameters are described: i) the prey taken and preferences ii) the skeletal part distribution iii) the long bone fragmentation iv) the tooth mark diversity and frequency. Information from hyaena ecology and the ungulate remains recovered from each bone accumulation reveals differences (or a lack thereof) related to environment anthropogenic pressure and ethology. Spotted hyaena hunting strategy and clan size suggest a low degree of inter group competition but high levels of intra group on carcass competition; fewer osteological remains are brought back to dens. In contrast striped and brown hyaenas are primarily scavengers (removing carcass remnants) and produce significant accumulations of bones at their dens. These differences are likely to be related mainly to inter specific competition and serve to reduce interaction with other carnivores and to limit kleptoparasitism; the composition of accumulations at dens is determined by food availability and foraging behaviour to a greater or lesser degree. Modern analogues are essential baseline tools for elucidating characteristics that might distinguish each species. The development of neo taphonomic models is the first step towards comparison and greater understanding of the palaeo ethology of extinct Pleistocene hyaenids.

The instruments of temporality played a key role in driving institutional action and political decision in the process of expansion of the European Union (EU) from 15 to 27 members. The Opinions made by the European Commission in 1997 on the countries of Central and Eastern Europe interpreted for the first time the ‘Copenhagen criteria’ for EU membership, and by using a ‘medium-term’ horizon introduced an important time-factor. The ‘roadmap’ developed by the Commission and approved by the Council of Ministers in 2000 effectively structured the decisive stages of the accession negotiations. In the ‘battle of dates’ with the applicant countries concerning the prospective timing of their accession, the EU refused to commit itself to a precise date until the last stages of the negotiations. Overall, it used time-factors in such a way that the existing members and the applicant countries were mobilized to reach a timely conclusion.
