Abstract. Antiarcha data are essential to quantitative studies of
basal jawed vertebrates. The absence of structured data on key groups of
early vertebrates, such as Antiarcha, has lagged in understanding their
diversity and distribution patterns. Previous works of early vertebrates
usually focused on anatomy and phylogeny, given their significant impacts on
the evolution of key characters, but lacked comprehensive structured data.
Here, we contribute an unprecedented open-access Antiarcha dataset covering
60 genera of 6025 specimens from the Ludfordian to the Famennian globally.
We have organized an expert team to collect and curate 142 publications
spanning from 1939 to 2021. Additionally, we have two-stage quality controls
in the process: domain experts examined the literature and senior experts
reviewed the results. In this paper, we give details of the data storage
structure and visualize these antiarch fossil sites on the paleogeographic
map. The novel Antiarcha dataset has tremendous research potential,
including testing previous qualitative hypotheses in biodiversity changes,
spatiotemporal distribution, evolution, and community composition. It is now
an essential part of the DeepBone database and will be updated with the latest
publication, also available on https://doi.org/10.5281/zenodo.6536446 (Pan and
Zhu, 2021).
Abstract. Antiarch placoderms, the most basal jawed vertebrates, have the potential to enlighten the origin of the last common ancestor of jawed vertebrates. Quantitative study based on credible data is more convincing than qualitative study. To reveal the antiarch distribution in space and time, we created a comprehensive structured dataset of antiarchs comprising 64 genera and 6025 records. This dataset, which includes associated chronological and geographic information, has been digitalized from academic publications manually into the DeepBone database as a dateset. We implemented the paleogeographic map marker to visualize the biogeography of antiarchs. The comprehensive data of Antiarcha allow us to generate its biodiversity and variation rate changes throughout its duration. Structured data of antiarchs has tremendous research potential, including testing hypotheses in the fields of the biodiversity changes, distribution, differentiation,population and community composition. Also, it will be easily accessible by the other tools to generate new understanding on the evolution of early vertebrates. The data file described in this paper is available on https://doi.org/10.5281/zenodo.5639529 (Pan and Zhu, 2021).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
