Palaeopascichnus is an Ediacaran fossil comprising a series of lobes, first originating before the Gaskiers glaciation;[1] it is plausibly a protozoan, but probably unrelated to the classical 'Ediacaran biota'.[2] Once thought to represent a trace fossil, it is now recognized as a body fossil[3] and corresponds to the skeleton of an agglutinating organism.[4]
