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).本仓库为本文手稿的配套补充仓库，包含研究所用的数据集与代码。我们开发了一种名为DeepMorph的全新方法，用于解析二叠纪-三叠纪大灭绝事件期间六大海洋演化支（即菊石类、双壳类、腕足类、腹足类、介形类及牙形石）的形态演化历程。本次上传的分类学数据集涵盖599个属及656张图像，时间跨度从晚二叠世最晚期（长兴阶）至早三叠世最早期（印度阶）。
