    #Chitonida (#Mollusca) exist since the #Cambrian. Bodies are covered with #calcareous #plates, flexibly connected. Most feed on vegetation cover. The #CambrianExplosion made based i.a. on #oxygen significant leaps in #animalevolution. Y. Zhang et al. (2025) assume a change in Earth's orbit altering #solarradiation, leading to land #weathering and #nutrients flow to the sea. Algae thrived and produced much oxygen.
