Periodic Reporting for period 1 - CroProLITE (Crop Production in the Levant and International Trade Exchange: investigating coprolites and crop plant remains from the 1st millennium CE Negev Highlands and Aravah Valley)
Période du rapport: 2022-09-01 au 2024-08-31
Results of this research indicate that the 1st c. BCE to the 4th c. CE marked a period of unprecedented crop diffusion in the Southern Levant – a phenomenon coined in project publications as “Roman Agricultural Diffusion” (RAD). In the Byzantine and Early Islamic periods, this new agricultural diversity becomes evident in Negev desert settlements, along with at least one crop species first introduced in the Early Islamic period: the aubergine. The latter represents a component of the “Islamic Green Revolution” (IGR). Considering the IGR and RAD together, the first millennium CE saw more new contributions to agricultural diversity than any previous millennium – and this appears to be the case throughout the Middle East and Mediterranean. However, in the Negev at least, none of the first millennium introductions are well-represented in archaeobotanical assemblages. This suggests that they did not quickly change local diets or landscapes, and supports a gradualist model for agricultural change over the last 10,000 years.
The CroProLITE project also made contributions to multi-proxy coprolite analysis—particularly of herbivore faecal pellets found at Negev desert sites. Project pilot studies demonstrated the value of micro-CT scanning as a screening technique for macroremain preservation, and of ancient DNA as an important source for dietary reconstruction. This complements previous and ongoing analyses of archaeobotanical proxies including seeds, pollen and phytoliths. An additional pilot study demonstrated the reliability of dung pellet exterior shavings for radiocarbon dating, making it possible to use an otherwise discarded source of contaminants. This will improve multi-proxy workflows to better unpack these rare time capsules of past economies and ecologies.

As time capsules of past economies and ecologies, ancient faeces, or coprolites, comprise a scarce but valuable archaeological resource. To make the most of the information encapsulated in them, developing multi-proxy workflows has been a focus of the CroProLITE project. During the project period this led me to participate in analyses of various types, including micro-CT scanning at the Paleolab, U. Cambridge McDonald Institute for Archaeological Research and at the Biotomography Centre, U. Cambridge Zoology Dept; proteomics and lipid extractions at the U. Copenhagen; ancient DNA extractions at the McDonald Institute’s Henry Wellcome Laboratory for Biomolecular Archaeology; radiocarbon pretreatments at the 14CHRONO Centre, Queen’s University Belfast; and stable isotope analyses at the Pitt Rivers Lab, McDonald Institute. Some results have been published (Fuks et al. 2023b), while more are forthcoming.

In September 2023, I had the honour of participating in the planting of a 1300-year-old variety of grapes on the outskirts of the UNESCO world heritage site, Avdat. Previous research demonstrated the significance of viticulture in this region during Late Antiquity (Fuks et al. 2020). Grape pips I retrieved from excavations led by Dr. Tali Erickson-Gini (Israel Antiquities Authority) and Prof. Scott Bucking (DePaul U.) at Early Islamic Avdat were DNA sequenced and identified to variety in a study led by Dr. Pnina Cohen, Dr. Meirav Meiri (Tel-Aviv U.) and Prof. Guy Bar-Oz (U. Haifa) (Cohen et al. 2022). With support of an ERC proof of concept grant awarded to Bar-Oz, those same varieties were then planted at the site for the first time in over 1,000 years! Lior Schwimer (Ben-Gurion U. and Nature and Parks Authority) oversaw the planting.
