Short summary

We use brachiopod fossil data to evaluate the Early Permian position of the South China Block (SCB) in three distinct global tectonic reconstructions. Faunal similarity indexes between the SCB and other tectonic plates indicate that the SCB was located centrally within the Paleo-Tethys Ocean during Early Permian times, rather than on its outskirts. We introduce an openly available framework that can be used to extend such analyses to other times, fossil assemblages, or tectonic reconstructions.
