利用氧同位素（δ 18 O）分析方法，研究了利比亚Gebel Akhdar地区Haua Fteah考古遗址从Epipaleolithic到新石器时代的贝类摄食季节。为了验证该种作为全年古环境记录者的可靠性，分析了现代贝壳和海水中δ 18 O的年内变化，并与实测的海表温度（SST）进行了比较。这些贝壳被认为是季节性贝类锻造研究的良好候选者，因为它们在其贝壳δ 18 O中几乎保留了完整的年度SST周期，生长减缓或停止的程度最小。在晚更新世早期表旧石器时代（当地称为Oranian，以2σ概率建模的日期为17.2-12.5 ka，Douka等人，2014年），考古标本的分析表明，贝类全年都在觅食。这补充了考古记录中的其他证据，这些证据表明洞穴在这一时期比之前或之后更密集。这一发现意义重大，因为奥兰期是Gebel Akhdar最后一次冰期循环中最寒冷和最干燥的阶段，增加了Gebel Akhdar可能在全球气候极端时期成为北非人类避难所的理论。晚更新世和全新世早期的软体动物开发，在晚更新世晚期（当地称为Capsian，c.12.7 - 9 ka）和新石器时代（c.12.7 - 9 ka）。8.5至5.4ka），主要发生在冬季。这些考古阶段的其他证据表明，狩猎活动发生在温暖的月份。因此，在Gebel Akhdar的全新世贝类开采的时间可能受到其他资源的季节性供应的影响，在这些时候，贝类可能被用作膳食补充剂时，其他食物不太丰富。
The seasonal pattern of shellfish foraging at the archaeological site of Haua Fteah in the Gebel Akhdar, Libya was investigated from the Epipaleolithic to the Neolithic via oxygen isotope (δ18O) analyses of the topshellPhorcus (Osilinus) turbinatus. To validate this species as faithful year-round palaeoenvironmental recorder, the intra-annual variability of δ18O in modern shells and sea water was analysed and compared with measured sea surface temperature (SST). The shells were found to be good candidates for seasonal shellfish forging studies as they preserve nearly the complete annual SST cycle in their shell δ18O with minimal slowing or stoppage of growth. During the terminal Pleistocene Early Epipaleolithic (locally known as the Oranian, with modeled dates of 17.2–12.5 ka at 2σ probability, Douka et al., 2014), analysis of archaeological specimens indicates that shellfish were foraged year-round. This complements other evidence from the archaeological record that shows that the cave was more intensively occupied in this period than before or afterwards. This finding is significant as the period of the Oranian was the coldest and driest phase of the last glacial cycle in the Gebel Akhdar, adding weight to the theory that the Gebel Akhdar may have served as arefugiumfor humans in North Africa during times of global climatic extremes. Mollusc exploitation in the Latest Pleistocene and Early Holocene, during the Late Epipaleolithic (locally known as the Capsian,c.12.7 to 9 ka) and the Neolithic (c. 8.5 to 5.4 ka), occurred predominantly during winter. Other evidence from these archaeological phases shows that hunting activities occurred during the warmer months. Therefore, the timing of Holocene shellfish exploitation in the Gebel Akhdar may have been influenced by the seasonal availability of other resources at these times and possibly shellfish were used as a dietary supplement when other foods were less abundant.
