In southern and south-eastern Arabia, the Neolithic developed between 6500 and 3100 BCE. In the Sultanate of Oman, occupation occurred along wadi banks, around paleolakes, and at large shellmiddens accumulated on the shores of the Arabian Sea. Nevertheless, the origins and development of human occupation on the Arabian Sea islands are poorly known, if not totally undocumented. After exploring the archaeological potential of the large island of Masirah, we focused our research on the small Al-Hallaniyat archipelago (formerly known as the Kuria Muria islands). A preliminary archaeological survey led us to test several sites belonging to different occupational phases on the island, and we explored the largest shell-midden at the HLY-4 site in 2014 and 2019. Radiocarbon dating results, along with lithic analysis, demonstrate that at around 4200-4000 BCE, a Neolithic community settled the largest island (Al-Hallaniyah). While goats and dogs had been introduced as livestock, fish and dolphins were regularly fished and captured as a main food resource together with marine turtles and nesting birds. At HLY-4, not only lithic and bone artifacts characterize the assemblage, as standardized discoid marine-shell beads were also manufactured. The Neolithic conquest of Masirah Island occurred early in the Neolithic (at the beginning of the sixth millennium BCE), while the settlements on the Farasan islands (in the Red Sea) are dated to around 4500 BCE, and thus the ones on the Al-Hallaniyat archipelago to the end of the fifth millennium BCE. In Arabia, their chronological assessment marks the final conquest of the insular areas. [ABSTRACT FROM AUTHOR]

We successfully measured four radiocarbon dates on two specimens of a black geometric rock painting with a fragment in jeopardy of naturally spalling off in the wall of a rock shelter in the Ẓufār region, in the south of the Sultanate of Oman. Extraction of carbon dioxide (CO2) for radiocarbon dating of the binder in the black pigment of the rock painting specimen was conducted in the plasma oxidation laboratory at the Office of Archeological Studies in Santa Fe, NM. The radiocarbon content was measured on the Swiss ETH-Zürich accelerator mass spectrometer MICADAS. The dates obtained agreed with one another within the statistical uncertainty and the average date of the four samples was 1500 ± 35 radiocarbon years BP. The calendric equivalents of the average date results in calendric calibration date ranges that span the mid-fifth through mid-seventh centuries (440–453 CE, 478–496 CE, and 534–646 CE). This research demonstrates that it is possible to date the black paintings of the Jebel al-Qara' area of Oman; this is the first pictogram that was dated using radiocarbon dating in the region.
