StratPal: An R package for creating stratigraphic paleobiology modeling pipelines

Abstract

O_LIThe fossil record is an important source of information to understand biological processes that take place over timescales not accessible to human observation or experiments. Fossil data is not a perfect reflection of past biological change, but a joint expression of stratigraphic, ecological, evolutionary, and taphonomic effects. Stratigraphic biology is a field dedicated to identifying these effects and accounting for them. C_LIO_LIWe present StratPal, a R package in which stratigraphic, ecological, evolutionary, and taphonomic modules can be combined into modeling pipelines for stratigraphic paleobiology. C_LIO_LIWe describe the types of data that can be modified and transformed using this approach, and briefly discuss potential extensions. C_LIO_LIAs working examples, we show how the pipeline can be used to model clustering of last occurrences at hiatuses and condensation surfaces, leading to artefactual "extinction events" caused by stratigraphic gaps.
