Supplementary information is included in the dataset for plotting
functionality (e.g. GTS2020 colour scheme).

datasets

Provides functionality to support data preparation and exploration for
palaeobiological analyses, improving code reproducibility and accessibility. The
wider aim of 'palaeoverse' is to bring the palaeobiological community together
to establish agreed standards. The package currently includes functionality for
data cleaning, binning (time and space), exploration, summarisation and
visualisation. Reference datasets (i.e. Geological Time Scales <https://stratigraphy.org/chart>)
and auxiliary functions are also provided. Details can be found in:
Jones et al., (2023) <doi: 10.1111/2041-210X.14099>.
