A novel specimen-based mid-Paleozoic dataset of antiarch placoderms (the most basal jawed vertebrates)

[摘要] Antiarcha data are essential to quantitative studies ofbasal jawed vertebrates. The absence of structured data on key groups ofearly vertebrates, such as Antiarcha, has lagged in understanding theirdiversity and distribution patterns. Previous works of early vertebratesusually focused on anatomy and phylogeny, given their significant impacts onthe evolution of key characters, but lacked comprehensive structured data.Here, we contribute an unprecedented open-access Antiarcha dataset covering60 genera of 6025 specimens from the Ludfordian to the Famennian globally.We have organized an expert team to collect and curate 142 publicationsspanning from 1939 to 2021. Additionally, we have two-stage quality controlsin the process: domain experts examined the literature and senior expertsreviewed the results. In this paper, we give details of the data storagestructure and visualize these antiarch fossil sites on the paleogeographicmap. The novel Antiarcha dataset has tremendous research potential,including testing previous qualitative hypotheses in biodiversity changes,spatiotemporal distribution, evolution, and community composition. It is nowan essential part of the DeepBone database and will be updated with the latestpublication, also available on https://doi.org/10.5281/zenodo.6536446 (Pan andZhu, 2021).
