Hollis post clean: ZooMS spectra for contaminated Hollis bone sample MUSE20026.40/41_ABA after consolidant removal using the standard ABA collagen extraction protocol. Labelled peaks show those used to identify the bone as elephant/mammoth. Shaded bands in the inset images indicate where rabbit markers would be expected if present (A—m/z 2129, B—m/z 2957, C—m/z 2973, D—m/z 2883).
