Vascular tissue ToF-SIMS spectra for "Nanoscopic imaging of ancient protein and vasculature offers new insight into soft tissue and biomolecule fossilization"

Raw, unprocessed ToF-SIMS spectra corresponding to Figure 6 and Figure 7 of the manuscript: "Nanoscopic imaging of ancient protein and vasculature offers new insight into soft tissue and biomolecule fossilization". These spectra represent raster scans of the surface of blood vessels (interpreted as basal endothelium) isolated from the following bone specimens: extant Bos taurus long-bone, extant Struthio camelus long-bone, extant Alligator mississippiensis long-bone, YG 610.2305 (Rangifer tarandus antler), YG 610.2363 (Bison priscus metatarsal), YG 610.2364 (Equus lambei metatarsal), YG 610.2365 (Bison priscus radius), YG 610.2397 (Mammuthus primigenius innominate), and YG 126.115 (Bison priscus tibia).
