text: Finally, the only potential sponge character in Palaeophragmodictya and some other alleged Precambrian sponges, the presence of apparent skeletal nets, has been discredited by a new study by Luzhnaya & Ivantsov (2019), who documented such structures in the characteristic Ediacaran fronds, which were never considered as sponges and certainly are not because they have no openings for water circulation.
