ALT Figure 2 of the manuscript. Data availability in palaeoproteomics. A) Percentage of ZooMS and shotgun palaeoproteomics studies with available datasets. Preprints and papers that did not produce any data were excluded from this calculation. B) Number of palaeoproteomics datasets in online repositories (since 2010). ´Other´ repositories include Dryad, Figshare, Github, Mendeley Data, and the OSF Framework. The dataset was compiled by manually going through the list of publications compiled for Figure 1 and checking raw data availability. This figure was made in R v.4.4.2. with R Studio v.2024.12.0+ (R Core Team, 2023) using ggplot2 (Wickham, 2016).
