The high potential of micro-magnetic resonance imaging for the identification of archaeological reeds. The case study of Tutankhamun

This study explores the potential of micro-magnetic resonance imaging ( -MRI) for identifying archaeological reeds found in the tomb of Tutankhamun. Reed plants had various historical uses in the past, with ancient Egyptians extensively employing them for crafting a wide range of items. The distinct cross-sectional characteristics of Arundo donax (giant reed) and Phragmites australis (common reed) are observed and described via optical microscopy and  -MRI in this study. While optical microscopy offers higher resolution,  -MRI provides advantages for studying archaeobotanical specimens, as it eliminates the need for mechanical sectioning and potentially damaging fragile samples. The application of  -MRI on a selected archaeological reed allowed us to identify it as Phragmites australis, showing that  -MRI can yield clear images, maintaining the integrity of the sample. In contrast, diagnostic features appeared greatly deformed on the thin section observed via optical microscopy. Despite the limitations related to the sample size and the need for sample soaking,  -MRI presents a valuable tool for analyzing archaeological remains in the field of cultural heritage, with the potential for broader applications. Overall, this study contributes to expanding the toolkit available to researchers studying plant remains, providing insights into reed identification and preservation in archaeological contexts.
