Do you want to know how the structure of the rock record affects your reconstructions of #biodiversity, #evolution rates or trait evolution? The groundwork for doing this has been laid down in the field of #StratigraphicPaleobiology but until now no software tools have been available to researchers in #paleobiology and #geoscience to evaluate distortion of their #FossilRecord.

Join the webinar on Building modeling pipelines for stratigraphic paleobiology in #RSoftware by my PhD student @Niklas_Hohmann in the Paleoverse lecture series hhttps://palaeoverse.org/lectures this Thursday at 4 PM UTC to learn how to use the new package StratPal developed in my European Research Council (ERC) project #MindTheGap

You can find the package with extensive documentation here: https://mindthegap-erc.github.io/StratPal/
More on the project: https://mindthegap-erc.github.io/

If you are interested in working with us on #StratigraphicPaleobiology, structure of the fossil record, and development of #OpenSource research software, please get in touch!

Stratigraphic Paleobiology Modeling Pipelines

The fossil record is a joint expression of ecological,…

Pereira et al. found that the turtle fossil record unveils two extinction surges: one during the end-Cretaceous mass extinction and another likely caused by our hominin ancestors. Read now ahead of print to find out more!
