Heterogeneous selectivity and morphological evolution of marine clades during the Permian-Triassic mass extinction

This is a supplementary repository, including the dataset and codes we used in this manuscript. we developed a new method, called DeepMorph to analyze the morphological evolution of six marine clades (i.e., ammonoids, bivalves, brachiopods, gastropods, ostracods, and conodonts  ) during the Permian-Triassic mass extinction events. The taxonomy dataset was uploaded and contains 599 genera and 656 images, spanning from the latest Permian (Changhsingian) to the earliest Triassic (Induan).
