Definition
Ediacaran period: An interval in the history of earth after the Marinoan/Varanger glaciation of the Neoproterozoic Era (see Chapter Snowball Earth), but before the Cambrian radiations. This interval marks the introduction of complex macroscopic organisms, leading to a revolution in the structure and evolution of marine paleocommunities, including the establishment of multi-level trophic structures, coevolutionary predator–prey interactions and infaunal activity.
Ediacaran biota: A highly distinctive assemblage of Ediacaran-age macroscopic organisms preserved as casts and moulds in siliciclastic, volcaniclastic, and carbonate sediments.
Introduction
Ediacaran biota is a heterogeneous assemblage representing the earliest known communities of macroscopic organisms. Diverse Ediacaran fossil assemblages are coeval with the earliest phosphatized metazoan embryos (Xiao et al., 1998; but see Bailey et al., 2007; Xiao et al., 2007), the earliest undisputed traces of metazoan...
