Due to its popularity, the animals from which ivory can be sourced are under threat of extinction. Identification of ivory species is not only important for CITES compliance, it can also provide information about the context in which a work was created. Here, we have developed a minimally invasive workflow to remove minimal amounts of material from precious objects and, using high-resolution mass spectrometry–based proteomics, identified the taxonomy of ivory and bone objects from The Metropolitan Museum of Art collection dating from as early as 4000 B.C. We built a proteomic database of underrepresented species based on exemplars from the American Museum of Natural History, and proposed alternative data analysis workflows for samples containing inconsistently preserved organic material. This application demonstrates extensive ivory species identification using proteomics to unlock sequence uncertainties, e.g., Leu/Ile discrimination. Explore

She has a Masters degree in Archaeology from the University of Cape Town (UCT), focusing on cultural identity of Khoe, San and Coloured women. She is a member of the A/Xarra Restorative Justice Forum in the Centre for Africa Studies (CAS), at UCT where she sits on the Language, Human Remains, and Women’s Commissions. Annelize currently holds the title of President of the Commonwealth Association of Museums (CAM) and is the Chairperson of the Western Cape division of South Africa Museums Association (SAMA). She is a huge advocate for decolonising museum spaces , the most important of which is the reburial and return of ancestral remains as well as objects from communities still in museums, and having previously marginalised and silenced communities, a voice in spaces where they were misrepresented. ABM CONFERENCES ABM MEMBER EVENTS ABM Roundtable Discussion - August 2024 Roundtable Speaker Perceptions of Human Remains - Continued Following the overwhelming response to our March 27th session. We are pleased to announce an upcoming online Roundtable discussion on the topic of human remains in museums, cultural centers, and religious spaces. This session will offer an opportunity to examine the ongoing ethical and practical challenges surrounding the display, handling, storage, treatment, and scientific analysis of human remains. It will also provide a space to share diverse institutional experiences and foster thoughtful dialogue across disciplines. 
Our goal is to generate actionable insights that can support professionals navigating these responsibilities, and to encourage a respectful, informed approach to working with human remains in varied contexts. We welcome participants from across the field to join us for what promises to be a meaningful and necessary conversation. Explore PUBLICATIONS + PROJECTS

Lackner [1], Solenn Ferron [2], Joël Boustie [2], Françoise Le Devehat [2], H. Thorsten Lumbsch [3], and Nobuko Shibayama [1] Unraveling a Historical Mystery: Identification of a Lichen Dye Source in a Fifteenth Century Medieval Tapestry As part of a long-term campaign to document, study, and conserve the Heroes tapestries from The Cloisters collection at The Metropolitan Museum of Art, organic colorant analysis of Julius Caesar (accession number 47.101.3) was performed. Analysis with liquid chromatography–quadrupole time-of-flight mass spectrometry (LC-qToF-MS) revealed the presence of several multiply chlorinated xanthones produced only by certain species of lichen. Various lichen dye sources have been documented in the literature for centuries and are classified as either ammonia fermentation method (AFM) or boiling water method (BWM) dyes based on their method of production. However, none of these known sources produce the distinctive metabolites present in the tapestry. LC-qToF-MS was also used to compare the chemical composition of the dyes in the tapestry with that of several species of crustose lichen. Lichen metabolites, including thiophanic acid and arthothelin, were definitively identified in the tapestry based on comparison with lichen xanthone standards and a reference of Lecanora sulphurata, confirming the presence of a lichen source. This finding marks the first time that lichen xanthones have been identified in a historic object and the first evidence that BWM lichen dyes may have been used prior to the eighteenth century.
