Since Tofugu members ate a mushroom called "panaeolus papilionaceus," there has been no end to the laughter in the Tofugu office.
Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means die out so the verb vocab version is to die out. You know that this one is "to die out" because you're up in the air (える), looking down at the dinosaurs, who are all dying out. Thank goodness you're up in the air, because the ground is all on fire.
The reading can come from 絶つ, so as long as you know that word you know this one as well.
