Broomcorn millet (Panicum miliaceum L.) is not one of the founder crops domesticated in Southwest Asia in the early Holocene, but was domesticated in northeast China by 6000 bc. In Europe, millet was ...reported in Early Neolithic contexts formed by 6000 bc, but recent radiocarbon dating of a dozen 'early' grains cast doubt on these claims. Archaeobotanical evidence reveals that millet was common in Europe from the 2nd millennium bc, when major societal and economic transformations took place in the Bronze Age. We conducted an extensive programme of AMS-dating of charred broomcorn millet grains from 75 prehistoric sites in Europe. Our Bayesian model reveals that millet cultivation began in Europe at the earliest during the sixteenth century bc, and spread rapidly during the fifteenth/fourteenth centuries bc. Broomcorn millet succeeds in exceptionally wide range of growing conditions and completes its lifecycle in less than three summer months. Offering an additional harvest and thus surplus food/fodder, it likely was a transformative innovation in European prehistoric agriculture previously based mainly on (winter) cropping of wheat and barley. We provide a new, high-resolution chronological framework for this key agricultural development that likely contributed to far-reaching changes in lifestyle in late 2nd millennium bc Europe.

The watermelon (Citrullus lanatus subsp. vulgaris) is among the world's most important fruit crops. We here use C‐14 dating and morphometric analysis to test whether ancient ...seeds can be identified to species level, which would help document food expansion, innovation, and diversity in Northeastern Africa. We dated a Libyan seed to 6182–6001 calibrated years BP, making it the oldest Citrullus seed known. Morphometric analysis could not reliably assign ancient seeds to particular species, but several seeds showed breakage patterns characteristic of modern watermelon seeds cracked by human teeth. Our study contributes to the understanding of the early history of watermelon use by humans, who may have mostly snacked on the seeds, and cautions against the use of morphology alone to identify Citrullus archaeological samples.

The object of the present study is the ancient bulb of the narcissus found on the mummy, probably of the Ptolemaic period, brought to Wrocław from Italy in the sixteenth century AD. For about four ...hundred years the mummy was kept by the successive owners of one of pharmacies in Wrocław, and after the World War II became the possession of Wrocław University. Computed tomography made in 2002 revealed an atypical object lying under the left hand of the mummy. Extracted in 2004 it appeared to be the bulb of a flower, and botanical analysis has revealed that it represents the Narcissus tazetta L. species. Although the narcissus was known in Egypt, its identification in the ancient sources has never been attempted. Thanks to the analysis of the bio-medical properties of the narcissus, compared with some descriptions of remedies proposed by the medical papyri Ebers and Hearts, as well as with some religious magical texts an identification of the sennut plant with narcissus is proposed here.
Changes in aquatic and marsh vegetation at Lake Zeribar in the Zagros Mountains, Iran, during the last 40 000 years were reconstructed on the basis of plant macrofossils. Several episodes of low ...water level and increased salinity were evidenced by peaks of Chenopodium rubrum seeds and the occurrence of obligate (Salicornia sp., Ruppia maritima and Suaeda sp.) and facultative (Zannichellia palustris) halophytic macrophytes as well as brackish water and marine diatoms. Some of these events can be correlated with an increase in diatoms indicative of higher conductivity and with changes in oxygen-isotope data. They are interpreted as the expression of general climatic dryness, although water-level changes might also have resulted from episodes of deposition on the alluvial fans that dam the lake. A few such water-level changes occurred in the Pleniglacial. The most pronounced lowering corresponds to the Younger Dryas interval of high climatic aridity. Macrofossil indicators of water-level changes appeared also in the Holocene section of the profiles at the same time as Quercus expanded on the surrounding uplands, culminating about 6000- 5000 14C yr BP, giving support to the hypothesis that the delay of forest expansion in this part of the Zagros Mountains was caused by climatic dryness.
During archaeological excavations of a medieval stronghold in Rozprza, a buried thick deposit of deep black (Dark Earth type) soil was discovered. A multianalytical (sedimentological, geochemical and ...archaeobotanical) study was carried out in order to identify traits the Rozprza Dark Earth. The analyses demonstrated that the soil was formed as an effect of surface accumulation of organic deposits from swampy areas and waste materials with rich admixtures of organic materials. The organic carbon content of the soil of the Rozprza Dark Earth was twice as high, and the total concentration of P was many times higher as compared with the adjacent soil outside the stronghold. Plant macroremains which were recorded within the buried soil and a cultural layer are evidence for human activity, mainly wood gathering and agriculture. In the Early Middle Ages, summer crops could be cultivated there with the use of tilling methods characteristic for root crops or gardens. The accumulation of the Rozprza Dark Earth commenced in the second half of the tenth century AD. In the period between the eleventh and thirteenth century, a ring-fort was established there. The deep black soil is partly covered by the ring-fort’s rampart. The rampart was built with the use of re-deposited earlier cultural layers and sand of the subsoil. It was then clad with sod bricks. Such a construction of a medieval rampart has been recorded for the first time in the territory of Poland. A new interpretation of archaeological structures and cultural layers offers a basis for new conclusions concerning the chronology and the development stages of the medieval settlement and ring-fort in Rozprza.
