Palaeopascichnus

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