The gang attempts to discuss the Ringo Starr of mass extinctions, the End Triassic. And much like the actual extinction event, the discussion is long, broad, and not focused on any one thing in particular. Meanwhile, Amanda learns the joys of screen sharing, Curt makes some dubious shopping decisions, and James “wins” (play along at home and count how many times James “wins” the podcast).

In this episode the gang discusses mimicry in the fossil record, which James uses as an excuse to introduce everyone to one of his “favorite” papers. And as they stare into the gaping maw of mimicry in slack-jawed disbelief, grim smiling lips float back to them flashing pearly teeth in the dark and whispering one word.... mouths.
