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.
