- The Aptian extinction was an extinction event of the early Cretaceous Period. It is dated to c. 116 or 117 million years ago, in the middle of the Aptian stage of the geological time scale, and has sometimes been termed the mid-Aptian extinction event as a result. It is classified as a minor extinction event, rather than a major event like the famous Cretaceous–Paleogene extinction event that brought about the end of the "age of dinosaurs" and the Mesozoic Era. The Aptian event is most readily detected among marine rather than terrestrial fossil deposits. Nonetheless, "From a palaeobotanical perspective, the Aptian Extinction Event is an episode of importance, deserving a higher status among other minor events." The Aptian event may have been causally connected with the Rahjamal Traps volcanism episode in the Bengal region of India, associated with the Kerguelen hotspot of volcanic activity. (At the time in question, c. 116–117 Ma, India was located in the southern Indian Ocean; plate tectonics had not yet moved the Indian landmass into its present position.)Note that the stegosaur group of dinosaurs went extinct around this time. Wuerhosaurus, probably the last of the stegosaurs, lived during this time. The tritylodonts, the last surviving relatives (but not members) of the mammals went extinct around this time too. These extinctions may be associated with this event. (en)
- 阿普第階滅絕事件（Aptian extinction）是個發生於白堊紀早期的小規模滅絕事件，年代為約1億1700萬年前到1億1600萬年前，大約是阿普第階中期。根據地層中的證據，阿普第階滅絕事件對海洋生物造成較大的影響，對陸地生物則較小。 位於印度孟加拉地區的Rahjamal暗色岩火山爆發，可能是阿普第階滅絕事件的原因。Rahjamal暗色岩是由凱爾蓋朗熱柱的火山爆發形成的（在這個時期，印度位於現今的南印度洋地帶）。 (zh)
