REMARKS: Though found most commonly in deep-sea settings, Paleodictyon evolved in shallow marine environments during the Late Precambrian and Early Cambrian and later migrated to deep marine environments by the Late Cambrian. Paleodictyon has been reported in Mesozoic and Cenozoic shallow marine deposits, and rarely in post-Cambrian Paleozoic shallow marine deposits.
