Jul 6, 2021 · D. anima, as well as the newly reported Tuzoia. sp. from the Fandian biota, represent the oldest occurrence of Tuzoiidae, extending its stratigraphic range to Cambrian Stage 3 and expanding the palaeogeographical distribution of the group to the northern border of the Yangtze Platform. The head of Tuzoia is also specialized: it bears one pair of differentiated cephalic appendages (potential mandibular palps) and at least two pairs of differentiated cephalothoracic legs.The association of trace fossils and non-biomineralized carapaces has been reported from Cambrian Lagerstätten worldwide, but the abundance, ichnodiversity, taphonomy and ecological significance of such associations have yet to be fully investigated.
