个人简介

代旭,中国地质大学(武汉)地球科学学院地球生物学系“地大百人”计划特任教授。


研究方向

地质历史时期生命与环境协同演化,重点关注古生代-中生代之交海洋生物演化。


研究兴趣与招生方向

1. 二叠纪-三叠纪之交生物大灭绝与海洋生态系统重建以及现代类型海洋生态系统的起源;

2. 头足类分类学、生物地层学、系统发生、生物多样性和生物古地理 

3. 计算古生物学(定量生物地层、多样性、生物古地理、形态测量、分支系统学等);

4. 深时极热事件背景下生物的演化规律;

5. 青藏高原三叠纪古生物学与地层学。

欢迎对古生物学与地层学感兴趣的本科生、硕士生、博士生及博士后邮件联系(xudai@cug.edu.cn)


主要学术成果

1. 发现贵阳生物群,揭示二叠纪-三叠纪之交生物大灭绝后海洋生态系统快速重建和现代类型海洋生态系统的雏形 (Dai et al., 2023, Science);

2. 建立了我国华南和藏南早三叠世格里斯巴赫亚期至史密斯亚期高精度菊石生物地层 (Dai et al., 2019, Journal of Paleontology; 2021, Global and Planetary Change; 2023, Earth-Science Reviews);

3. 发现早三叠世格里斯巴赫亚期一次快速生物复苏现象,并提出生物多幕式复苏模式 (Dai et al., 2018, GSA Bulletin);

4. 揭示二叠纪-三叠纪生物大灭绝事件中菊石形态演化过程,否定了前人在Science论文中认为的非选择性灭绝模式 (Dai et al., 2021, Geology);

5. 定量证实早三叠世菊石出现了两次全球化现象并阐明了其内在机制 (Dai et al., 2020, Paleobiology)。

研究成果三次入选中国古生物学年度十大进展。
