摘要研究了西特提斯(匈牙利和希腊九头蛇)碳酸盐岩台地环境中的中二叠世碳酸盐岩灭绝和恢复事件。这些剖面的年龄模式分辨率较差，我们在牙形刺和有孔虫数据的支持下，建立了13C化学地层对比方案，试图与中国地区的测年事件进行对比。这揭示了所有特提斯地区事件的时间安排是相似的：首都中期的灭绝损失产生了匈牙利和九头蛇的晚期首都组合，具有明显的晚二叠世特征(例如，它们缺乏大型的丝虫)。没有证据表明瓜达卢皮亚末期(首都)发生了灭绝事件，这表明之前关于瓜达卢尼亚末期大灭绝的说法是基于对首都中期事件的不良记录。基准面在中晚二叠世过渡期的大部分时间里是稳定的，除了在首都阶段发生了一次重大的倒退。随后的海侵形成了广泛的浅水碳酸盐沉积，如九头蛇的Episkopi组和匈牙利的Nagyvisnyó石灰岩组。
Abstract The Capitanian (middle Permian) extinction and recovery event is examined in carbonate platform settings from western Tethys (Hungary and Hydra, Greece). The age model for these sections is poorly resolved and we have constructed a 13C chemostratigraphic correlation scheme, supported by conodont and foraminifer data, which attempts correlation with the well-dated events in China. This reveals the timing of events was similar in all Tethyan regions: extinction losses in the middle of the Capitanian produced late Capitanian assemblages in Hungary and Hydra with a distinctive late Permian character (for example, they lack large fusulinaceans). There is no evidence for an extinction event at the end of the Guadalupian (Capitanian) suggesting that previous claims for an end-Guadalupian mass extinction are based on poorly dated records of a mid-Capitanian event. Base level was stable through much of the middle–late Permian transition with the exception of a major regression within the Capitanian Stage. The subsequent transgression established widespread shallow-water carbonate deposition, such as the Episkopi Formation in Hydra and the Nagyvisnyó Limestone Formation in Hungary.
