Chitons and the Origin of Eyes

This is Episode 3 of the Mark & Mark Paleo Pod. Our topic this time is Chitons, the Proterozoic Clemente Biota of México, its significance for the Cambrian Explosion, and the Origin of Eyes. Discussed here is Clementechiton, a Precambrian stem chiton that preserves the oldest known eyes in the fossil record. Episode 3 features new PaleoArt of ancient chitons, some never before reconstructed! Thanks to Alyssa Calcagno for video production and editing! PaleoArt: Mark McMenamin.
