森诺曼期－土仑期灭绝事件（英语：Cenomanian-Turonian boundary event，简称OAE2），是发生于白垩纪的二个海洋含氧量降低物种灭绝事件之一。 K-T Tr-J P-T Late D O-S 单位：百万年 本图仅呈现地质年代各期的海洋生物灭绝比例，包含规模最大的五次灭绝事件。蓝色部份代表大致的灭绝属比例，以该时期与下一时期的化石纪录比较计算。 该次事件大约发生于9150±860万年前[1]，不过亦有研究指出其约发生于9300—9400万年前[2]。 参见 生物集群灭绝 海洋含氧量降低 白垩纪—古近纪灭绝事件 参考资料 [1]U-Pb and Re-Os geochronology of the Aptian/Albian and Cenomanian/Turonian stage boundaries : implications for timescale calibration, osmium seawater composition and Re-Os systematics in organic-rich sediments - NERC Open Research Archive.
