Mass extinctions are critical turning points in the history of life and those that occurred during episodes of sudden climate warming record a similar suite of co-occurring, interlinked environmental changes (Jaraula et al., 2013). A key challenge is to determine which of these factors were most important in driving specific aspects of extinction, recovery and ecological change in marine ecosystems (Danise et al., 2015). One of the most important such crises occurred at the end of the Triassic Period (~201.5 Ma) and was driven by catastrophic release of greenhouse gases during emplacement of the Central Atlantic Magmatic Province (CAMP) (Kasprak et al., 2015). Although a number of studies have separately investigated global changes in the biosphere and geosphere during this event, a detailed understanding of how marine ecosystems responded to climate-related abiotic changes during the extinction, its aftermath and subsequent recovery is lacking.

大灭绝是生命史上的关键转折点，在气候突然变暖期间发生的大灭绝记录了一系列类似的共同发生的、相互关联的环境变化（Jaraula et al., 2013）。一个关键的挑战是确定哪些因素在推动海洋生态系统中灭绝、恢复和生态变化的具体方面最为重要（Danise et al., 2015）。最重要的危机之一发生在三叠纪末期（~201.5 Ma），是由中大西洋岩浆省（CAMP）就位期间温室气体的灾难性释放所驱动的（Kasprak et al., 2015）。尽管许多研究分别调查了这一事件期间生物圈和地圈的全球变化，但对海洋生态系统如何在灭绝期间、其后果和随后的恢复中对气候相关的非生物变化作出反应的详细了解尚缺乏。
